Scalp Reduction: This is a process where the area of the bald skin is decreased on the head. With time, the skin on the head becomes stretchable and flexible enough so that small sections of this skin can be removed surgically. After the hairless portion of the scalp is removed, the space is closed with hair-covered scalp. This procedure takes time to show results. The scalp reduction method is usually used in combination with hair transplantation. This ensures a natural looking hairline. It is best for those with extensive hair loss.
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.
