TRI Design Ecollogen Shampoo - Hair Shampoo For Natural Hair - Moisturizing, Hydrating - Gentle Hair Products, Thickening, Volumizing Shampoo - Liter (33.8 oz.)

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

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

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 have been using this product for over 30 years. Beauticians tell me I have healthy hair and my friends comment on how it shines. I am thankful that Amazon carries it.

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.

Liked the way it cleaned my hair. Have been using this product over 20 years. Nothing is better!
