Awesome! Excellent product and prompt shipping! Ecollagen shampoo by Tri removes the build up.

It’s a great balanced shampoo and I’ve used it for years.

This doesn't strip color at all, and leaves hair easy to manage. I have straight, fine, stringy hair; but this makes it manageable, with a little boost.

I’ve been using this for years and will continue to use it

an excellent mild shampoo. It can also be used as a face and body soap.

I have fine thin color-treated hair and it has been difficult to find products that clean/condition without weighing down my hair -- and I've tried many priced high to low. This is the best by far! I noticed incredible shine after first use. It seems to coat each hair giving more volume. Love the light scent too. I'm a new customer who is totally impressed. After the first use, a friend said that I was having the Best Hair Day ever!

I use this shampoo every time I wash my hair. I like that my hair doesn’t look greasy for a few days. This shampoo was first used on me by my hairdresser. The scent is clean and fresh.

I have allergies and have been looking for a shampoo thatd oesn't irritate my scalp but still leaves hair feeling soft while clean. At my stylist's suggestion I already use the Tri unific energy moisturizer/conditioner with good results (love the minty smell) and decided to give this a try. It's just what I was looking for- hair feels clean, soft and manageable and no itchy scalp! Good value and a very nice product.
