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. There is only anecdotal evidence that oral or topical application garlic , onion juice, saw palmetto, coconut oil, evening primrose oil , apple cider vinegar, creatine, and pumpkin seed oil are of benefit for hair loss.
Normally, about 10% of scalp hairs are in the telogen phase. During this three-month period, the hair root shrivels up into a small white "club," then the hair falls out. It is normal to lose about 100 hairs every day, more of them on days when shampooing loosens the hairs that are ready to fall out. The body then replaces the hairs. Sometimes people worried about losing their hair start noticing hairs on their pillow or in the sink, not realizing that they've always been there. A close look at these will usually reveal the white club at the end, showing that these hairs were already dead!
