Cosmetic Hair Thickeners These can give excellent effects on thinning hair. They are not suitable for bald areas as they need some hair to attach to. Some contain minute fibres which cling electrostatically to hair giving it more body as well as colour. Those which are just colours do not work so well. Remember too that these are cosmetics, they have no effect on the hair loss itself. Still, they can be extremely useful in concealing hair loss or for use whilst waiting for treatments/surgery to work. 

Dutasteride Dutasteride, like finasteride, inhibits the action of the enzyme 5 alpha-reductase and hence blocks the production of DHT. However, there are in fact two forms of 5-alpha reductase and whereas finasteride only inhibits one type, dutasteride inhibits both types. At the time of writing Dutasteride is to be used for the treatment of Benign Prostatic Hyperplasia (BPH). However, there is much speculation that this substance would be a very effective treatment for hair loss and it is hoped by many that clinical trials specifically related to hair loss will be concluded. Like finasteride, it would be a male only treatment and, because of the nature of its action, could give rise to side effects such as loss of sexual appetite in certain individuals.
