"Let me start by saying, I absolutely LOVE this brand! However, this product did not live up to my expectation. It smells great, but it didn’t do much for my hair as far as leaving it feeling any different. The shampoo, conditioner, and oil work fantastic for me, but this, not so much."
"This overnight mask is truly remarkable! At first, I was concerned that it might make my hair feel greasy or weigh it down with heavy product. However, I was pleasantly surprised. The formula is incredibly lightweight, and it absorbed into my hair while I slept. When I woke up, my hair felt incredibly soft, smooth, and revitalized. It’s a game changer for my nighttime routine!"
"I love MO, so I decided to try the new product. I didn't have high expectations because I thought it might feel/look too heavy/greasy, but I was wrong! I used it once and received so many compliments. It smells amazing, lasts for days, and helped with my hair frizz. I don't wear my hair down often in the summer since it will frizz, but now I can when I use this! It feels super healthy after, and I'm excited to wear my hair naturally more."
"Love this overnight mask! I have used it over night as instructed and also during the day with my styling process and can see the change and am left with shiny health hair. Would definitely make this part of my daily routine from now on and would highly recommend."
"I was worried this would be too heavy for my hair type, but I have loved it so far! Does not seem to weight my hair down and has that great Moroccan Oil scent!! Made my hair soft but not too soft that it's unmanageable."
"My hair felt silky and soft after only one use. I will be using this regularly to maintin my hair. I might see if I can get my husband to use it also."
"Very light weight. I have fine hair so I was concerned but it doesn’t weigh it down."
"This product made my hair softer and more manageable. I did feel however that it made my hair look slightly greasy."
"It smells AMAZING. Made my hair soft and not greasy feeling after using it"
"Another great item Moroccanoil has come out with. Easy to use, leaves hair looking full and shiny."
