I'm not sure if you were looking for a natural cure, however, I know of two products, which have grown back the edges of a 58 year old woman. I say her age because we all know the older you get, the harder it is to get your hair to grow. The first item she used was NX3 by Nioxin. Actually, the whole kit is pretty good for thinning hair period. The second is a little hard to come by unless you live in a hispanic area or go to a hispanic salon. Its called Canela oil and its base is cinammon oil. Now this is the one you apply to a specific area, usually if you have a bald spot somewhere. It stings a little, but its worked everytime I've seen it. You might be able to find it on the web, as I'm sure you can find Nioxin. Hope it goes well.
