Didn't do much for frizz
This product was gifted by moroccanoil in return for my honest feedback. I liked how soft and smooth my hair felt after using this mask, but unfortunately it didn't do much for my frizz. I was hoping for a little more smoothing and frizz control, so overall it was just okay for me.

Love it!!
I got this overnight mask gifted by moroccanoil and I love it! It goes on so well and really soaks into my hair. Then it leaves my hair so soft and manageable the next day! I have hard water so my hair really takes a beating and this has revived it so well.
Amazing mask
I used this mask after every hair wash, and I am so impressed with how it not only makes my hair look but feel. It's so smooth and amazing! I love it so much and would recommend it to everyone! Ten out of ten! Gifted by moroccanoil
I would buy this again!
I really enjoyed this Overnight Leave-In Hair Mask, As a wavy haired girl, moisture is essential for my curl pattern. It washed out well, and left my hair hydrated, bouncy, and so soft! (gifted by moroccanoil)
Good
gifted by moroccanoil I really liked this overnight hair mask; I have dry, damaged, and color-treated hair, and it really saves it. In the morning, my hair is very soft, silky, and easier to detangle. I highly recommend trying it to anyone with dry and unruly hair.

Love this
Love love love this! I leave it on overnight and the next day it makes my hair feel so nice and soft. Very easy to apply you just leave it in your hair damp or dry and you don't have to wash it. Will need more of this! Gifted by moroccanoil.
