Light and Airy Feel

This hair mask makes my low porosity hair feel super lightweight, like I just got a fresh haircut. After styling, my hair feels so soft, shiny, and voluminous. It’s so expensive but I really love it!!

Smells amazing! Made my hair feel so soft and shiney. My mom used it and it brought a few of her curls back to life just after one use! Yes its pricey but I would definitely buy it again.

It is helping my hair stay hydrated. But it didn't work when my hair was damaged. So, I would recommend it if your hair isn't damaged to begin with.

Helps you get healthy hair again

[I received this product in exchange for my honest review] I really love this Kerastase hair mask. It is a really thick formula that you work through wet hair, let sit, and then rinse out. A little bit goes a long way. I use just a small amount for my whole head of hair that is thick and above the shoulder. The first few weeks I was using about 3 times a week, but as the weeks have gone on I only use about once or twice now. It has left my hair shiny and I notice a lot less broken ends.

What my hair needed

[I received this product in exchange for my honest review] Best hair mask I’ve ever tried. Leaves my hair so soft and no more frizz for me! A little goes along way, literally only need a small amount to work wonders. Smells really nice and it makes it super easy to detangle my hair. Might be a bit pricey but I think it should last you about 6 months so i believe it’s worthy!

[I received this product in exchange for my honest review] This was exactly the product I’ve been looking for lately because my hair is dry and brittle after bleaching and heat styling. I needed something that was nourishing and reconstructive, and that is exactly what this mask does for me. It’s nice and thick, but easy to apply even to fine hair, and it smells great as well with a light scent. It leaves my hair feeling soft and silky.

[I received this product in exchange for my honest review] This product worked magic on my hair. Left it feeling soft and not to heavy on my thing hair. 5 mins or less in your hair and 1x per week. Packaging was very easy to use, excited to see how much it will reduce breakage over time!

Great hair mask! Repair your hair from the first a

In the first application the first thing I noticed was its incredible aroma and when I rinsed my hair I saw an immediate change. Everyone asks what shampoo or perfume I use on my hair and I recommend this product.
