The product is preferably applied to wet hair, on the tips and longueurs.Il has no parfum.Mes hair being long, I used several doses applicateur.Après use of hair dryer, my hair was found more volumisée.Le smoothing iron was more efficient, with a record much more stiff, but may be at the expense of a little brillance.Le conditioning mask a rather small volume of product, so its cost is quite high!
