PRP is one other procedure that medics believe helps in regrowing the lost hair. Though there is very limited evidence that PRP can grow the hair back, most medics believe that it can surely help stop hair fall and regrow lost hair.
Alopecia areata refers to an auto-immune condition that results in unexpected hair fall (or hair loss). Though this is not a common problem but it affects a large population. In people suffering from alopecia areata, hair fall in chunks can be noticed, often the size of a small coin. In extreme cases, hair fall can be very severe resulting in no hair on scalp or anywhere (scalp, body, eye brows, nostrils etc) on the body.
