Ok... Ce produit est miraculeux 🥹 J'ai hésité pendant longtemps avant de l'acheter. J'avais l'habitude de payer 500$ pour des lissages et donc je me suis dit que j'allais m'essayer. D'abord, le produit est très fort lorsqu'on lapplique, ça pique la gorge et ça brûle les yeux. Faites le dans un endroit super aéré. MAIS, une fois terminé (ça m'a pris 3h30 mais j'ai les cheveux ultra longs), mes cheveux étaient vraiment beaux. J'ai laissé le produit pendant 3 jours. Quand je suis sortie de la douche, je les ai laissé sécher à l'air (voir la dernière photo) . Mes cheveux sont magnifiques!! 💕💕💕 ils sont ultra doux et souples et presque plus de frisottis et le grichou est parti! Mes cheveux étaient morts et ce produit a fait de la magie. Merci mille fois 🩷🩷 n'hésitez pas, çest un life changing.

I followed the instructions-shampooed twice, blowed dry, put in the product. Combed through, removing excess, blowed dry, flat ironed. I waited 3 days to wash my hair. I did hit it with the flat iron in a few places where I tend to be frizzy. For an over the counter product without formaldehyde, I think this is a good price and reasonably effective. Not quite as good as a salon, but easy, convenient, and much less expensive. The photos are a few days after, no heat applied, just brushed it off my face.

I bought this product for a do it at home ordeal .I took me half a day to complete everything, while attending to the kids and the house. I watched tons of YouTube videos before deciding to do the at home treatment. I separated my hair in 4 sections , by the time I got to the front and was applying the product , my eyes started to burn and there was this one section on my scalp that felt like o was getting a relaxer… even though I didn’t saturate my hair or scalp in that area.There’s enough left in the bottle for 2-3 more treatment however I’m not so sure I’ll be using it again , just because of the burning sensation on the scalp.I left the product in as recommended but only until the next day .My hair came out great.It did what it was supposed to do. My hair is silky soft and more manageable.I’ve just started the Olaplex brand treatment just to try maintain this keratin goodness.

I bought the larger size to use in my hair and a friend. I still have enough for probably another use for the both of us, although we have short shoulder length hair. Our hair textures are thick, wirey hair (we are Asian and Native American). As some others have noted, the chemicals get VERY strong so you’re going to want to turn on the fan, vents and window. My eyes were burning when I was working on the hair closer to my face. For my hair, I’m pretty experienced working on it myself, and I’m very thoughrough so I was able to do it myself. I the. Proceeded to apply it to my friends hair. Followed the instructions to the T. We have our hair a bit over 24 hours before we washed it with sulfate free shampoo and straightened it again. Our hair was very soft and shiny. Loved it. We continued to straighten our hair every night for the next 3 days. After that we only straighter our hair every other day. It remained great for a month, and probably would have lasted longer if we continued with the ritual of straightening our hair every other night. It does take a long time and it’s messy and smelly, but it’s worth it.
