Don't waste your time and money on this product. It does not even deserve one star.
I just received my shipment of the Hair Revitalizer, and it is a greasy sludgy mess. It is a leave-in product, however, has the consistency of hand lotion and it looks and feels like you put that in your hair. I had to wash my hair twice and still feel like I didn't get all of the gunk out of my hair. Seriously makes me wonder how legit this product is as no reputable hair product would be like this. I suppose if you were a bald-headed man it would not be as disgusting, but as a person who needs to go out in public, I don't want it to look like I dumped the grease bucket on my head. Impossible to style your hair with this gunk in it.
They did process a refund, but I have to pay return Priority Shipping. I have to wait to see if they actually credit my account. What a rip off. It costs me $12. As a person suffering from hair loss, I am disgusted in how many companies are out there just to rip you off. Add this one to the list.
Bottom Line: No, I would not recommend this to a friend
