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.

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.

Hair will feel great!
SampledPurchased

I got a sample of this and knew I had to buy it! Leaves your hair feeling like silk. Not greasy. Nice, thick formula. Smells fresh when using but doesnt seem to leave a smell in your hair (I like that because I was you to smell my perfume not a mix of every product Ive used). I think its the best deep conditioner ever. I use it like once a week and see such a difference afterwards.

Phenomenal for Long, Tangled, Dry Hair
Sampled

This masque was a savior to my hair. My hair is waist length and thick so it is very dry and has horrible damage but with only one use of this masque, my hair feels AMAZING. I highly recommend this to anyone with brittle hair and a dry scalp. I also color my hair which causes awful tangles that with one simple application of this product, completely vanished. You will thank yourself when you feel your soft, untangled hair and smell how great the scent of the masque is.

Super Nourishing

I bought this in conjunction with the shampoo and conditioner. Using it once a week leaves my hair feeling moisturized, soft and manageable.
