Birchbox Breakdown

If we had to describe our ideal skin and hair, we’d use some of the same adjectives: smooth and glowing. So it makes sense that Kérastase would take inspiration from skincare to create this versatile sculpting serum. It’s infused with two tried-and-true skincare ingredients—alpha hydroxy acid and ceramides—to help you achieve sleek, ultrashiny locks, whether you’re blow-drying or going heat-free. Not only that, but the weightless formula keeps strands soft and bouncy

How to Use

Dispense 2-3 pumps of product into palms, making sure to press evenly to release equal amounts of both formulas. Work through towel-dried hair, concentrating on lengths and ends. Style as usual. Can also be applied to dry hair from mid-lengths to ends to add shine.

Love the smell and straightening

I love kerastase products. My hair is blonde, long, fine but I have a lot of it and it's dry and frizzy. I love the smell of this. Light, fruity and fresh. Not musky. Phew! I used 3 squirts before blow drying and a squirt after. The squirt after is essential.

I really like the smell of both sample products although I would've preferred a small bottle sample versus packets. I feel like I would consider the product more if I got more than one use out of it.

excellent shampoo

The May box had a sample of this shampoo. My hair is thick and usually has an unmanageable frizz. With this product I could instantly feel the difference. Even while washing my hair, it felt soft. I finished off with the conditioner whichave was not as great as the shampoo. In just one wash my hair felt soft and shiny. Am definitely getting this shampoo.
