Ordered a trial of both shampoos and tried it out for a few days. I definitely am hooked on them. Makes the hair thicker but without over drying it like Revita shampoo did. Its similar to Revita. Basically the treatment shampoo is identical to Revivogen shampoo which I love and also similar to Nioxin shampoo which I used many many years ago and seemed to like as well. So basically, its a mixture of of Revivogen shampoo and Nioxin mixed into one shampoo. I think I like it better than Revivogen now. I also tried out another product called Living Proof thickening cream too and that stuff helps thicken up the hair as well. So I would definitely recommend this shampoo. You can trial a sample for 6 dollars. When I saw the ingredients were similar to Revivogen shampoo plus some added bonus stuff like emu oil and caffeine, I figured it was worth a try. So in summary, Regenepure used with Living Proof thickening cream equals COSMETICALLY thicker, fuller hair. And if the shampoo helps to reduce hair loss, that would be a bonus too.
