Biotine

Biotin is a B vitamin recommended for hair health. Deficiency of biotin can lead to thinning of the hair. Using biotin enriched shampoos or using biotin as supplements can be beneficial to someone suffering from hairloss or hair thinng or brittle nails.
I don't use this supplement on daily basis but take it weekly or biweekly.
