The key to making your hair thicker is feeding it and even more importantly, making sure nutrients are able to access the hairs via the bloodstream. There are three key methods to achieving this:
1. Increase the supply of key amino acids that grow hair keratin
2. Increase the direct supply of blood to the hair follicles
3. Remove barriers to the hair follicles blood supply
The first two are relatively easy and by using the first two methods just about anyone can make their hair grow thicker. However results will be limited if you don’t also complete the third method.
