Also known as vitamin B7 (or vitamin H), biotin is a water-soluble vitamin which naturally supports hair growth by helping to create amino acids and promoting production of keratin (the main component of hair). Long story short, biotin is believed to strengthen existing strands as well as nourish growing hair follicles, improving thickness and durability in the long run.

Thinning hair and hair loss are common symptoms of biotin deficiency. While biotin has proven benefits for hair gross in people with biotin deficiencies, it is not proven to have any effect on healthy people.
However, segments of population such as pregnant women or elderly persons are particularly subject to biotin deficiencies.

Biotin exists in edible form, like gummies. If taken excessively, they are not always safe. Instead of eating biotin like candies, you’d better add it to your hair cleansing routine with a natural and vegan biotin shampoo.
