I don't know what i expected however, the amount of hair loss has been reduced considerably. I do have to use a conditioner in addition to this as my hair is my drier with this product.This is an update after going through my first bottle of GKHair . A couple of months ago, my hair was thinning and and many strands a day were falling out. Today, I can't say my hair is thicker, but I can say I am not loosing hair at any rate I was a few months ago. Combine this with taking hair growth vitamins and reducing my stress level, I am quite happy with this product. Also, a note from my barber, I actually have new hair growing. ALL POSITIVE EVENTS. I HAVE AND WILL CONTINUE TO PURCHASE AND USE GKHair SHAMPOO.
