I have extremely straight fine hair and have never found a shampoo/conditioner that actually helped and thickness and volume before until I tried this. I can't believe the difference it has made to my hair.

It has made my hair grow long and strong my hair was not growing and would break off after using this for two years now my hair is longer, stronger, and fuller I really recomend this product.

[This review was collected as part of a promotion.] i don’t typically love drugstore hair products, so i’m not surprised that this did nothing for me. it smells fine, but it doesn’t add any volume or texture to the hair.

I HAVE USED THE ORIGINAL SHAMPOO THICK AND FULL FOR YEARS AND YEARS...I DO NOT LIKE THIS NEW UPDATED VERSION AND I THREW IT AWAY. YOU RUINED IT BY GIVING IT VOLUME AND TEXTURE. THE ORIGINAL IS A 10 STARS...PLEASE BRING IT BACK AGAIN...THANK YOU

My hair is flat and doesn't really have volume. When i used this it gave so much volume and shine to my hair. And the smell is great! Not harsh to the nose. It also helps with hair fall.
