Worth it!!

I LOVE this stuff! I use it once a week and can really notice a difference in my hair. It leaves my hair feeling softer, silky, and more manageable. It makes it easier to comb out the tangles and hair appears less damaged.

The Keratherapy Conditioning Masque made my hair so soft and shiny! I have fine, thin hair and was afraid this would make my hair greasy, but it did just the opposite. I really enjoyed the sent of the conditioning masque as well, and loved how it worked with my hair.

Smells weird but made my hair shiny

This deep conditioner/ mask did make my hair healthier but it smells kinda weird like a musky smell even after I washed my hair with normal shampoo.

Nice mask, but it's nothing extraordinary. It was fun for one time use, as I'm a big fan of hair masks, but probably wouldn't buy it.

Sleek

Shiny, Soft, Smoothed, Sexy hair. These products are fantastic! This conditioner feels like such an indulgence-it is so thick and creamy...your hair just eats it up. Post rinsing, your hair is smooth, quenched and healthier feeling, with NO residue.
I'm sold...this is my forever conditioner!

I could use this product as a regular conditioner but wasn't my favorite mask. A little pricey for what it does. Not my favorite.
