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.

Great lightweight leave in treatment!
gifted by Moroccanoil. I apply this leave-in treatment and let it stay in-there's no need to rinse it out. The consistency isn't thick, which makes it perfect for a leave-in treatment. After I use it, my hair feels soft, smooth, moisturized, and easier to manage. It's lightweight, doesn't feel greasy, and doesn't weigh my hair down. It works well whether I leave my hair naturally curly or do a blowout.


Love it
I received the Overnight Treatment Mask complimentary from moroccanoil for my honest review and opinion. It has really improved the hydration in my hair, leaving it so soft and shiny. I will definitely be keeping this one in my routine.

So in love with my hair after using this…
