Very good for dry hair
I have course, thick, dry Mediterranean hair. Putting this on my ends has really helped my hair feel a lot softer and healthier.

Worth it
Great for damaged hair, brings shine to hard water damage. It’s a very thick texture so only need to use minimal, the bottle has lasted me very long so great value for money

Tengo decoloración en todo mi cabello, y este aceite no mancha mi rubio como otros aceites tipo moroccanoil.

En combinaison avec le k18 crème restructuration sublime les cheveux abîmés ou ternes. Les rends soyeux et brillants.

This hair oil is pricey but it has really made a difference. I have colour-treated hair and live in an area with hard water that has lots of minerals in it. This means my hair has become dry and listless. What I really like about this hair oil is that it doesn't seem to build up. It smoothes my flyaways and make the ends look healthy. I have long hair (several inches below my shoulders) so I need to use a few more drops than most. I also use a couple of drops at night on my ends and put my hair in a top knot. There is a visible change in my hair and I'm quite pleased. Highly recommend.
