Concerned
Stage 1 is the preventative stage of hair loss and typically occurs in the late teens to mid-late 20s, a period when most individuals are still experiencing their full hair density. During this stage, hair thinning may not yet be noticeable, but it's an ideal time to take proactive steps to preserve hair health and prevent future loss. Genetics, lifestyle, and environmental factors can begin to influence the hair's overall health, even if the thinning is not yet visible.
