When I use Nutrasome alone, I dont see any thickening cosmetic result. But, I mix Nutrasome with Thicker Fuller Hair and a little Nizoral. The result is a very thick sampoo mix which I think that provide me with a good thickening cosmetic result. I use this sampoo mix on the Nizoral off days. I leave it on my hair for 3-5 minutes. I dont know if this compination of two different thickening formulas (of Nutrasome and Thicker Fuller Hair) is the thing that makes my hair thick-looking.
I will try TRevor sorbie too. cheers Sean
