What are the Best Nutrients for Hair Growth?

A few aspects of hair growth are out of your hands. Your genetics and age, for example, are set in stone and can’t be changed. Fortunately, there is one factor that is well within your control – the nutrients you consume. Nutrients have a significant impact on hair growth. And fortunately, you can choose which nutrients you take in. 

How do vitamins and minerals help with hair loss? 

Your hair is important for your self-image, but it’s not ultimately necessary for keeping you alive. Hair thrives in a well-nourished environment. But when your health is compromised, your body diverts nutrients from areas like your scalp to more life-sustaining vital organs. Therefore, good health keeps more hair on your head. 

Although the hair you see on your head is made up of cells that are not “living,” those precious strands grow from tissues that are very much alive. Each strand grows from a follicle on the scalp, which is part of the body’s largest organ – your skin. Small blood vessels at the base of each follicle nourish the hair root to keep it growing.

The average person has about 100,000 hairs, all at various stages of growth. Hair grows, rests,  falls out, and is replaced through a naturally occurring cycle. Some stages of development require specific vitamins and minerals to keep the process going smoothly. 

As a result, your diet and health play a significant role in how quickly your hair grows. Good nutrition creates the framework for healthy hair and can help slow hair loss. So, while there’s no magic bullet that will regrow your hair instantly, there are nutrients that help keep more strands on your head. 

Hair Growth and Nutrients

Some vitamins and minerals are more effective at keeping hair healthy than others. So, if you’re attempting to prevent hair loss or regrow your hair, a targeted approach is the way to go. Boosting your intake of specific hair-friendly nutrients offers you the best prevention for hair loss — and keeps you healthy overall. The following is a list of the best nutrients for hair loss.

Keratin

Hair and nails are primarily made of a protein called keratin, so it’s no surprise that keratin is a vital nutrient for strong hair. This structural protein provides the structure and strength required for hair health, making strands less likely to break off or become damaged. Without enough keratin, cells within each strand of hair overlap unevenly, making their bonds weak and vulnerable to breakage. Keratin — as well as nutrients that encourage keratin formation— allows more hair to remain on your head and keeps every hair shaft strong. (01)

Biotin

Vitamin B7 or vitamin H, otherwise known as biotin, aids in keratin production. Without enough biotin, the hair shaft becomes weak, brittle, and slow to grow. Keratin cells, also known as keratinocytes, are like the bricks that make up each strand of hair. Without enough materials to make the bricks, hair can’t grow or form well enough to maintain its strength. Although biotin deficiency is rare, excessive alcohol consumption and some medical conditions can result in a lack of biotin. Biotin supplementation, whether administered through topicals, shampoos, or orally, can boost hair growth and thickness. (02)

Collagen

Most people are familiar with collagen in regard to skincare, but collagen is also essential for healthy hair. In a recent study published in the International Journal of Trichology, targeted nutritional supplementation primarily consisting of collagen was found to increase hair density in participants with a hair loss condition called telogen effluvium. Collagen improves hair growth during crucial growth cycles and limits hair loss during hair’s telogen phase – when hair typically falls out naturally.  (03)

Saw Palmetto

Individuals who experience male or female pattern baldness typically have an overabundance of a hormone called dihydrotestosterone (DHT). Excessive levels of DHT impact hair follicles by shrinking the follicle, increasing the chances of premature hair loss and preventing new growth. Saw palmetto, a plant extract, has been found to have DHT-blocking solid effects and can slow hair loss caused by DHT.  For people experiencing problems with baldness, saw palmetto supplements may offer relief when used with other boosts. (04)

Vitamin A

Vitamin A is a powerful micronutrient that significantly impacts hair growth. The body breaks vitamin A down into retinoic acid and retinol, which both regulate hair follicle stem cells and hair growth cycles. Therefore, a deficiency in vitamin A may lead to poor hair growth and hair loss. Furthermore, oxidative stress may hasten hair loss – especially in the case of alopecia areata. Antioxidants like vitamin A can help counter oxidative effects on hair. 

(05, 06)

Vitamin D

Despite the fact that the human body generates vitamin D from sun exposure, most people don’t get enough vitamin D.  Vitamin D deficiency can occur due to: 

  • A lack of vitamin D in the diet. 
  • Too little time spent in the sun. 
  • Difficulty absorbing vitamin D from food. 
  • Medical problems prevent the body from converting vitamin D. 
  • Medications that interfere with vitamin D levels. 

Fortunately, vitamin D is also found in foods like eggs or fatty fish and in vitamin-fortified foods. Even then, however, some people still don’t obtain enough vitamin D to grow healthy hair. Vitamin D keeps hair follicles in good shape and maintains robust hair growth. A deficiency in vitamin D may result in hair loss and bald patches. (06)

Probiotics

Recent studies indicate intestinal (gut) health plays a more prominent role in overall physical health than previously thought. Within the intestinal tract are bacteria, called the “intestinal microbiome,”  that depends on a specific environment to help break down food and keep the body functioning. An unbalanced microbiome can lead to inflammation, digestive problems, and skin conditions affecting the hair. 

Probiotics are bacteria and yeasts ingested to keep the intestinal microbiome healthy and stable. Current research shows that regulation of the intestinal microbiome using probiotics can boost immunity, help treat a myriad of metabolic conditions, and may even help alleviate the symptoms of some mental health conditions. Healthy intestinal health through probiotics can also give you thicker, more lustrous hair! (07, 08)

Ashwagandha 

According to a recent study published in the Journal of Clinical and Aesthetic Dermatology, ashwagandha supplementation was shown to reduce hair thinning in a cohort of both men and women. Data from the study indicate that supplements with ashwagandha can reduce hair loss on all types of hair, encompassing many ethnicities. At the end of the 24-week study, 83% of men and 79% of women showed improvement in hair quality, scalp coverage, volume, and thickness. (09)

Healthy Hair Through Nutrient Supplementation 

The process of growing hair calls for specific nutrients. Without enough nutrients to feed the follicles, hair becomes brittle grows slowly. So, if you’re looking to keep your scalp and hair healthy, you’ll need to start from the inside.

The Best Superfoods for Healthy Hair

Hair loss can often leave a person feeling helpless about their appearance. Fortunately, there are lifestyle changes a person can make to encourage healthy hair growth.  For example, replacing processed foods with nutrient-dense superfoods may help manage hair loss. 

Nutrients for Hair Growth

Like the rest of the body, the scalp depends on vitamins and minerals from the food you eat to grow healthy hair. Hair grows out through hair follicles, and these follicles need nutrients to work well. The following are a few of the most vital nutrients necessary for hair growth. 

Vitamin A

Healthy follicles are important for robust hair growth. Vitamin A ensures well-functioning follicles by promoting better blood circulation and mitigating follicle damage from free radicals. Additionally, vitamin A improves overall scalp condition, eliminating dry and scaly skin. 

B Vitamins

Deficiencies in B vitamins have been linked to hair loss. B vitamins support the growth of skin, hair, and nails in two ways: 

  • Enhancing the body’s ability to remove nutrients from foods. 
  • Boost red blood cell formation. 

A variety of nutrients fall under the umbrella of a B vitamin: (01)

  • B1 (also known as Thiamine)
  • B2 (also known as Riboflavin)
  • B3 (also known as Niacin)
  • B5 (also known as Pantothenic acid)
  • B6
  • B7 (also known as Biotin)
  • B9 (also known as Folate)
  • B12

Hair-friendly B vitamins help with red blood cell formation, which are vital for carrying oxygen and nutrients throughout the body— including the scalp. 

Vitamin C

A healthy head of hair is nearly impossible without Vitamin C. It’s a powerful antioxidant that impacts hair growth by: (02)

  • Playing a significant role in developing collagen, which is necessary for hair building and structure. 
  • Encouraging the absorption of iron, which prevents hair loss and oxidative stress. 

Like the rest of the body, the scalp and hair is susceptible to damage from free radicals. Vitamin C helps to reduce the injury from free radicals and maintains scalp health. Furthermore, collagen is a key compound that produces keratin, which gives skin and hair cells their structure. Vitamin C amps up collagen production and helps to strengthen and grow healthy hair. 

Vitamin D

Due to our modern lifestyle and diet, most people do not get enough vitamin D. Which is unfortunate, because vitamin D deficiency is linked to hair loss and slow hair growth. Participants in a study of women experiencing hair loss had lower levels of vitamin D. In another study of individuals with alopecia areata (an autoimmune condition that causes hair loss) found that vitamin D levels were also lower in individuals with the disease. (03, 04)

Iron

While many people don’t get enough vitamin D, the most common nutrient deficiency in the world is iron deficiency. Iron plays a significant role in a variety of body systems, but perhaps it’s most well-known for carrying oxygen throughout the body via red blood cells. Without iron, hair follicles can’t get the oxygen they need to grow hair. Therefore, iron deficiency results in anemia and hair loss. (02)

Zinc

Bones, muscles, the immune system, and even reproductive organs all require zinc to function appropriately. Zinc is also essential for healthy hair and skin. This mineral plays a significant role in manufacturing collagen, essential for growing hair. (02)

In addition, zinc affects the hormone dihydrotestosterone (DHT). DHT is responsible for the loss of hair in situations like male pattern.  Zinc regulates the activity of the enzyme that keeps DHT in check, 5-alpha reductase.

Seven Superfoods for Hair Loss

The good news is that you can easily obtain these vital hair nutrients by incorporating the following superfoods in your diet. You’ll find some predictable foods on this list, as well as some you may not have expected to be hair-growing superfoods! 

1 Nuts and Seeds

In general, nuts and seeds are high-protein and nutrient-dense superfoods. When it comes to hair, however, they’re chock full of the nutrients necessary for long, shiny hair. Nuts and seeds are high in B vitamins, iron, zinc, selenium, and omega-3 fatty acids. Just keep your intake to a handful a day, because nuts and seeds are also high in calories. 

2 Healthy Cuts of Meat

Meat gets a bad rap. Although it’s true that fatty or heavily processed meats adversely affect a person’s health, this is not the case for all types of meat. Moderate amounts of healthy cuts of meat are rich in nutrients and can help maintain a healthy head of hair. Red meat is full of an easily absorbable type of iron that works especially well in the blood’s oxygen delivery system, which helps bring oxygen to hair follicles. 

3 Oysters

Oysters are more than purported aphrodisiacs, they’re also great for growing hair. These delectable mollusks are low-calorie and high in nutrients, with the minerals it takes to make hair healthy. A 3.5-ounce of oysters provides the following percentage of a person’s daily required nutrients: (05)

  • Selenium: 56% 
  • Iron: 40% 
  • Vitamin B12: 538%
  • Zinc: 555%

These whopping percentages indicate how high oysters are in many of the nutrients needed to grow hair. 

4 Spinach 

In addition to muscles, perhaps spinach should have blessed Popeye with a full head of hair. Spinach is filled with nutrients that benefit both muscles and hair. Loaded with plant-based iron, vitamin C, and vitamin A, spinach can help keep hair follicles and strands healthy. 

5 Eggs 

One superfood that contains what you need for healthy hair are eggs. Hair is mostly protein (collagen and keratin) and eggs are a rich non-red meat source of protein. High in vitamin A, vitamin E, and B vitamins like folate and biotin, eggs help keep strands strong and healthy. Eggs also do wonders for the scalp by infusing the area with nutrients, allowing healthier  follicles to hang on to hair. 

6 Oats 

You’re probably aware that oats are high in fiber, which is beneficial for the digestive system. But did you know oats improve the health of your hair? Oats contain fatty acids and omega-3 fatty acids that reduce excess scalp oils and soothe inflammation, helping prevent hair loss in stress-related cases like telogen effluvium. Furthermore, oat is high in zinc, which keeps strands sturdy and less prone to breakage. (06)

7 Peas

Just like oats, green peas are a surprising superfood that’s good for your hair. Because green peas are full of iron and zinc, they strengthen hair and stimulate growth. Additionally, peas are also high in protein, which helps prevent or slow down hair loss. Interestingly enough, research regarding pea sprouts has shown promising results in slowing hair loss. (07)

You’re More than What You Eat

The saying goes that you are what you eat. While this may be true, you’re also more than what you consume. The environment, your genes, and your lifestyle all play some role in your health. And although a healthy well-balanced diet goes a long way to keeping a healthy head of hair, sometimes it takes more than superfoods to grow your locks back. For those cases, Happy Head is here to help. Our board-certified dermatologists will review your case and make recommendations that are unique to your needs.

Diet and Hair Loss: Is There a Relationship?

 

When you’re losing your hair, you’ll try just about anything to make it stop.  Shampoos, conditioners, essential oils, vitamins… they’re all fair game.  The easier and less invasive, the better.  So, it’s only natural that diet is a hot topic.  Diet is a manageable lifestyle change that could make a difference.  

But, if you’re like most people, you probably have more questions than answers when it comes to how diet and nutrition affect your hair.  According to a 2017 study conducted by the International Food Information Council (IFIC), there’s a lot of conflicting information, causing confusion about what to eat.  Determining whether specific foods will help or hurt your hair loss condition is even more challenging.  We hear it all the time from patients.  “Can alopecia be reversed by changing my diet?”  “Which diet will best reduce the inflammation on my scalp?”  “Do I have to go gluten, dairy, and sugar-free?”  

Before you resort to radical measures, keep reading.  We’ll help you separate truth from fiction and share firsthand information from our own Dr. Ben Behnam, board-certified dermatologist and co-owner of Happy Head hair loss solutions.  

Can Improving Your Diet Prevent Further Hair Loss and Stimulate Growth?

Does what you eat affect your hair?  That’s the question that most people want to be answered.  After all, why bother changing your diet if it won’t make a difference?  The answer is yes; nutrition may indeed affect your hair.  One study found that nutritional deficiencies can cause telogen effluvium, androgenetic alopecia, or alopecia areata. It also found that over-supplementation can lead to hair loss as well.  

The Wrong Diet Really Can Cause Scalp Inflammation

Nutritional deficiencies aren’t the only problem.  Scalp inflammation caused by an unhealthy diet is another issue.  A high fat, high-cholesterol diet has been found to stimulate the inflammatory process on the scalp.  A study conducted in 2018 found that mice who were fed a traditional western diet experienced skin discoloration, inflammation, and hair loss.  The mice’s hair turned black, gray, then white before falling out.  The diet, which induced inflammation, mimicked the aging process in humans and aged the mice’s hair by 36 weeks.  The hypothesis is that when what you eat generates an inflammatory response, it causes your hair to age prematurely.  

Which Diet Should You Choose to Prevent Hair Loss?

Now that we’ve established that the wrong diet is a recipe for disaster when it comes to your hair, which diet should you consider?  Keto, Autoimmune Protocol (AIP), Mediterranean… the list of possibilities seems endless.   The truth is that further research is needed on the use of diet in alopecia treatment.  One study indicates that the Mediterranean diet, which contains foods with anti-inflammatory properties, may stimulate hair growth and health among people with androgenetic alopecia.  Figuring out the differences between each diet gets tricky, though. In many cases, overlap exists in the philosophies behind the diets.  

A Protein-rich Diet Helps Build Keratin

Regardless of which diet you choose, it’s important to select a protein-rich diet filled with fresh, unprocessed foods.  Hair is primarily composed of keratin, a mixture of filament-forming proteins.  To make keratin, your body needs protein.  All protein is not created equal, though, according to Dr. Behnam.  “Select pasture-raised chickens, raised on a farm and not in a cage,” says Behnam.  “When chickens are trapped in a cage, their testosterone levels increase from the stress of being in the cage.  When you eat caged chicken, you get extra testosterone that can potentially convert to DHT leading to more hair loss.”

Vegetarians Often Lack Enough Protein in Their Diets

Dr. Behnam finds that his patients who are vegetarians tend to lack the protein and vitamins necessary for adequate hair growth.  We’ll talk a little more about vitamins later, so let’s focus on protein for now.  Some excellent sources of plant protein can compensate for animal protein.  Those sources include nuts and nut butter, lentils, beans, peas, leafy green vegetables such as broccoli, spinach, and brussel sprouts.  

Dr. Behnam is a big advocate of protein powder, not only for vegetarians, but for all of his patients.  It’s important to use the right type, though.  According to Behnam, “Two types of protein powder are on the market.  One is whey protein isolate. Whey protein isolate powder is easily found in retail stores in muscle milk, and other types of sports shakes.  It’s less expensive.  The only problem is that whey protein isolate increases the concentration of amino acids such as valine and isoleucine, which lead to higher testosterone production.  That extra testosterone has the potential to convert to DHT and cause hair loss.  The solution is to use whey protein concentrate.  Whey protein concentrate is harder to find, but it will boost your protein without increasing your testosterone or DHT levels.”  

Do You Have to Give Up Caffeine?

If you can’t seem to get moving in the morning without a cup of coffee, don’t despair.  “Caffeine doesn’t affect testosterone levels,” says Dr. Behnam.  “You can enjoy it without worrying.  I recommend that you stay away from energy drinks, soy milk, and anything high in MSG, though.”  

Nutritional Supplements

Vitamins and supplements aren’t a big deal to most people.  You don’t need a prescription to get them, so they’re safe, right?  Not so fast.  Vitamins and supplements aren’t always as innocuous as they seem.  There are a couple of things you need to know:

  1. The FDA does not regulate dietary supplements
  2. Over-supplementation of selenium, Vitamin A, Vitamin E, and other vitamins have been associated with hair loss

That said, Dr. Behnam usually tests his patients’ Vitamin D and iron levels because deficiencies are prevalent and are well-documented reasons for hair loss.  Vitamin D plays a crucial role in the hair growth cycle.   While the exact reason why iron deficiency causes hair loss is unknown, reversal of iron deficiency in mice led to a reversal of hair  loss.  

Here’s the inside scoop on other essential vitamins:

Biotin

There has been a lot of hype about biotin supplements, shampoos, conditioners, and more.  Truth be told, biotin deficiency is rare.  Clinical trials have not shown biotin to be effective in stimulating hair growth without a true deficiency.  

Zinc

Zinc deficiency can be either acquired or inherited.  It is common among vegetarians since vegetables contain less zinc than meat.   Zinc deficiency causes telogen effluvium and brittle hair.

Vitamin A

Vitamin A is the main ingredient in retinoids and retinoic acid.  It has been proven to work in conjunction with Minoxidil and Finasteride to increase absorption of the medications.  Vitamin A deficiency does not cause hair loss, although a connection between over-supplementation and hair loss has been found.  

Vitamin E

It’s not common for people to have vitamin E deficiencies.  More research needs to be conducted, but in one small study with 21 participants, people who received vitamin E supplements had an increase in hair count compared to people in the placebo group.  Too much vitamin E is too much of a good thing.  It can increase the risk of bleeding and decrease thyroid hormone production, resulting in hair loss.   

Balancing Your Diet Is A Process

Learning how to eat for healthy hair takes time.  Sometimes you don’t know if changing your eating habits or adding a particular vitamin will help until you try it.  If you’ve already been diagnosed with male or female pattern hair loss or some other type of alopecia, supplementing your diet with topical medications such as Minoxidil, Finasteride, Spironolactone, or Duasteride may be a good option for you.  Topical medications have been found to be as effective as oral medications without the bothersome side effects.  Even better, like your diet, our formulas can be customized to meet your specific needs.  For more information, contact us to determine whether you are a good candidate for Happy Head or one of our other prescription-grade hair loss solutions.
