Biotin and pantothenic acid (vitamin B5) have been used as alternative treatments for hair loss. Biotin benefits your hair by rebuilding hair shingles that have been damaged from over-shampooing, exposure to the sun, blow-drying and ironing. Vitamin B5 supports the adrenal glands, which helps stimulate hair growth.
Specific vitamin and mineral deficiencies like iron or vitamin B12 may be diagnosed by blood tests and treated. Multiple vitamins, including biotin, have been promoted for hair growth, but solid scientific studies for many of these claims are lacking. While taking biotin and other supplements marketed for hair, skin, and nails probably won't worsen anything, it may also not necessarily help the situation. Therefore, advertised hair-regrowth supplements should be approached with mild caution.
