2 types of Kérastase essences

I've been using these two combinations lately.

My hair, which used to be like a green onion root, has definitely improved.

I heard everyone raving about how good it was, so I decided to give it a try. Even though it's a bit pricey, I think I made a good purchase. For the green one, apply it to wet hair and blow-dry.

And use the yellow one on dry hair~
