Big fan of Kerastese but this really disappointedI brought this about 3 weeks ago and I wash my hair on alternate days cuz I live in a really humid climate hence need to blowdry it pretty often. My natural hair texture is straight , fine, frizz free and here’s my experience so far-
a) smells terrible too too strong gives me a headache honestly like a cheap men’s perfume
b) feels heavy in the sense that it gives me really bad buildup
So in totality it really doesn’t do much for my hair if not make it a huge hassle to deal with instead.

Smells divine and feels nourishingThis thermique is nourishing and moisturising. I like it on non humid days ! Please ensure the product is sealed well when sending it to us. There was a minor spillage when it arrived! But it’s a great product !
