Evaluation of the Efficacy of a Food Supplement in Reducing Hair Loss in Male Subjects

According to the American Hair Loss Association, by the age of 35, two-thirds of American men will have some degree of appreciable hair loss, and by the age of 50, approximately 50 to 85% of men will have significant hair thinning.

Hair is an essential aspect of human appearance and can have a significant impact on a person's self-esteem, mood and quality of life. Unfortunately, current treatment options can be costly, tedious or painful. They are also associated with numerous side effects.

Here, the investigators aimed at evaluating the effect of a new food supplement on hair condition in young men suffering from hair loss. A second goal was to determine tolerability.
