I just bought this product and have started using daily with the complimenting conditioner. I LOVE both the shampoo and conditioner. I have really noticed a difference in the health/appearance of my hair and others have too. Strongly recommend!

I remember using Terax products when they were an exclusive European product (I think!). When I saw the new packaging I worried that the product inside had been 're-worked'. I found this particular 'Collagene' and have been pleased with it's healing results. The smell is not for everyone but is typical of the brand. If the improvement to my frizzy, overprocessed hair continues so too will my using this shampoo.

My hair hasn't felt this silky in a million years! I have crazy "Manon des sources" hair (to the small of my back, fine but abundant, dark blond with who-knows-how-many years' worth of foils, hasn't been cut in a year, hopelessly tangled). I've been trying to eliminate luxury products from my lifestyle, but after fours months of hard water and products from Fantastic Sam's, I just couldn't take it anymore. I hated my hair so very much. I hadn't used Terax products for several years because of a painful association (I used to use the Latte shampoo on my dog but after he died seeing reminders like the word "Terax" would send me wailing with grief). But my hair felt like glass and I was desperate. My hair is actually naturally oily because I have an oily scalp. But my hair is so very, very long and so very damaged that when I saw the word "brittle" I thought, "I'll try that one." I bought the Collagene shampoo and the Crema conditioner. My hair is soft and shiny and youthful again. My hair thanks me. And I've decided to keep it long. I love this shampoo. It's Maxwell House coffee for me now instead of Starbucks because I ain't scrimpin' no mo' on my hair and skin products. I was slightly disappointed to see that Terax is now an American brand. Back when I used it, it was Italian. The Crema is a bit different, a bit less concentrated than it used to be, but that's OK. It's this shampoo, though, that has me deliriously happy,. And it's not really quite as expensive as it seems, when you look at the weights and measures and not just the price tags, And despite being sulfate-free, it lathers better than I expected and I used less than expected. Sorry this was so long. My hair insisted that I praise Terax -- and in particular the Collagene shampoo -- to the heavens.

delightful shampoo. love the smell and it treats my dry, color-processed hair well. i use it daily and this has become my favorite shampoo, although i have tried many others, in all price ranges. i use it with terax conditioner and my hair looks beautiful.

Best shampoo I have ever used, and I am really picky. My hair feels soft and shiny.

This is fantastic.

I did not think that this shampoo offered enough "slip" factor and eventhough it is supposed to be reparative, I could not get my fingers through my hair. It has a slight vanilla- coconut smell. I prefer a clean scent.
