Bio Protein Organic Brazilian Keratin Treatment - Formaldehyde-Free Hair Straightening, Keratina Brasileña, 100ml/3.38oz

After using this protein hair straightening kit, my hair looks noticeably smoother and shinier. It helped reduce frizz and left my hair straight with a very natural finish. My hair feels soft, healthy, and much more manageable. The results lasted well, and I’m very happy with how professional my hair looks after using this kit.

Love it ! It works, hair is soft and looks good, easy to apply. Not completely straightened the hair as you which you will always want to do blower after washing for a very straight effect

Didn’t do anything to my hair so please save your money

I've been color-treating my hair my entire adult life and was told keratin treatments like this were out of the question. I stopped getting highlights about a year ago (still get base color) and decided it might be time to try straightening the bangs. This product worked well. By the time I was ready for another treatment (5 mos later), the product was close to expiring, so I decided to risk it and do my entire head. It worked great! It was easy to apply and there was no damage to the non-bleached areas. I don't blow-dry my hair often, so this treatment leaves my air-dried curls more controlled without a lot of styling product.

Excelente producto capilar

I bought this treatment to try something more natural and I was delighted. I used it on my mom, who has short hair, and her hair was much softer, more manageable, and had a beautiful shine from the first use. I love that it's formaldehyde-free and has natural ingredients like coconut oil. It's ideal for fine or delicate hair. An excellent option if you're looking to straighten without damaging it! Plus, it arrived in perfect condition and on time.

The product was okay.

I've had my Keratin treatments done professionally for 5 years. I then tried the "Answr" which was great, and I as very pleased with the at home results. A friend suggested I try this brand. Not a good idea! It left my hair unmanageable. I couldn't put a comb through it.

Is very bad for pregnant women, i buy it it was last month of expiration and have formalin

It was a good experience, no bad odor no toxic fumes worked well but it's a small amount so if you have long hair you need at least 2 to 3 bottles other than that it's great straightened my hair and it feels soft and manageable even bounces lol.

Riktigt dåligt kvalitet

Je pensais que 1 bouteille ç'était suffisant parce que j'avais les cheuveux court, mais je me suis trompée. Mes cheveux sont resté pareil sans aucun changement , j'ai fais tout ça pour rien, j'ai suivi les étapes et les recommandations à la lettre, je suis déçue, je pense à aller voir un professionnel. 🥲

This is simply the best straightening product I’ve ever used in my life!! Will only buy this pruduct from now on!
