excellent result [SEP] updatestarstarstarstarstarvery happy with the outcome it s not artificial flat but very natural feel as if i just got my hair done at a solonfragrance is very niceok i did not apply the way they they suggested i applied it all by myself no extra hands i tried to follow their steps but i go frustrated doing it and practically it s impossible to follow those steps if you are doing it aloneso eventually i ended up almost massaging it on my hair and let it sit for minutes blow drying the hair after that is the hardest part trust me it took me minutes or more to do that and eventually i used an old towel to remove the excess of this serum to dry my hair and then ran the blow dryer again still it wasn t dry after that i ironed my hair hard but not as hard as blow drying eventually i washed my hair and blow dried them again and the outcome was stunning better than what i got from a salon i had paid for that but it was less hassle as i didn t have to do anythingoh btw their video link on the brochure doesn t work i tried times different days so they need to correct itif you want an outcome it will deliver i will update how long does this last because my last salon keratin last me around months which was great
