Review This Product

This product actually delivers what it promises! With it the smooth effect lasts much longer, especially when my root is growing and is more difficult to hold the brush! Recommend!

I straightened my hair almost daily and this serum not only protects it from both blowdryer and straightener but also leaves the hair silky and shiny. I can't live without it.

Andrea, Spain

I have straightened hair, it's great to use before dying, when it's still wet. I recommend using it even if you don't want to iron because it leaves the hair in the place where it should be!

I like this product because it protects my hair from the heat of the plate, the hair is more shiny, smooth the last long and protects hair from humidity and I would not change ever.

comprei para proteger do secador e baby liss. fiquei com receio de que ele ficasse pesado, mas ao contrário, ele deixa o cabelo muito bom, e o efeito do baby liss dura mais ainda, pq esse produto já tem fixação também :) . e depois ainda coloquei o Osis dust it, adorei

J'aime ce produit, car il permet un lissage parfait, qui résiste à l'humidité et mes cheveux sont impeccables, jusqu'au shampooing suivant , un gain de temps, et d'économie , car je l’utilise seulement le jour du coiffage, et résultat garanti pour plusieurs jours


I bought this product without many expectations, but wow... It's amazing to use before straightening irons. Leaves hair shiny.
