Bio Protein Botox Hair Treatment - Formaldehyde-Free Straightening, Anti-Frizz Keratin with Organic Keratin for Sleek Hair, 1kg

⭐️⭐️⭐️⭐️⭐️ Smooth, shiny, frizz-free hair after first use. Feels salon quality and very nourishing.

This is a product that I've been waiting for for years! It straightens the hair just enough to keep it soft and manageable, yet not stick straight to where it falls in your face. I have wavy hair naturally, but have always hated it. This product straightens out that mess with out you looking like a dough boy's helmet from WW1. It's kind of a pricey investment but when you see the huge amount that you get and how long it will last it's cheap. This is best hair product that I have ever purchased, hands down.

Muy buena queratina, resultados duraderos La queratina me gustó mucho. Respeta el cabello, no lo decolora, es suave y no irrita. He probado muchos productos de queratina y este ha sido de los mejores. Deja el cabello bonito y los resultados duran bastante. ¡La recomiendo! ⭐️⭐️⭐️⭐️⭐️ Very good keratin, long-lasting results I really liked this keratin. It respects the hair, doesn’t discolor it, is gentle, and doesn’t cause irritation. I’ve tried many keratin products, and this has been one of the best. It leaves the hair smooth and shiny, and the results last a long time. I totally recommend it!

I have battled with my coarse frizzy hair my entire life. I’ve had it professionally straightened and have battled with the flat iron daily. Humidity, sweat, a swim….. and it all goes down the drain I ended up cutting my hair super short for a few years because I just couldn’t deal with the constant blow drying and straightening Recently decided to let my hair grow again and was about to give up on it once the July heat and humidity set in then I found this product and read the reviews and said what the heck I’ll give it a try I am absolutely blown away I thought maybe it was just going to be that one day of nice hair but it’s been two weeks and I have even let it just air dry for the first time in my life, and it dried almost entirely straight and no frizz and it looked like normal hair for the first time ever ! It even moves when i shake my head lol if you know you know! Update: it is now 4 1/2 months after the first treatment and I did do it again about a month ago. I standby what I said previously and I am even more impressed with how long this lasts and for the first time in my life I feel like I have normal hair! Absolute game changer!

This treatment honestly worked just as well as the salon services I’ve paid for — but with a huge bonus: it’s organic, formaldehyde-free, and doesn’t come with that awful chemical smell. Instead, it has a much lighter scent that makes the whole process so much more pleasant. The application was straightforward. I washed my hair, towel-dried it, applied the product evenly, let it process, and then sealed it in with a flat iron as directed. The results were immediate — my hair came out sleek, soft, and shiny without the heavy coated feeling some treatments leave behind. The frizz was gone, and the smoothness has lasted through multiple washes. I love knowing I can get salon-quality results at home without worrying about harsh fumes or damage. For anyone dealing with frizz or wanting a straighter, healthier look, this is absolutely worth the investment. Only reason giving 4 stars is because after second wash it’s wavier and not as straight as it was after initial usage and wash. But it’s still frizz free and feels and looks great!

We are repeat customers. Excellent product with excellent results. Highly recommended has used this product many years

This keratin treatment does not work. I’ve done 3 treatments total and it just leaves my hair frizzy after every treatment.

Buen producto para alisar sin maltratar el cabello. Lo usé por primera vez y el resultado fue muy bueno: el pelo quedó más brillante, suave y muchísimo más manejable. Se nota que hidrata bastante por los aceites y proteínas que contiene. Lo que me gustó: ✔ No tiene olor fuerte ni químico ✔ Reduce el frizz desde el primer uso ✔ Deja el cabello suave y brillante ✔ La cantidad rinde bastante ✔ Se puede usar en casa sin complicación Lo que podría mejorar: – Tarda un poco en actuar, pero vale la pena – Es mejor sellarlo con plancha para maximizar el efecto En general, un tratamiento excelente si quieres resultados profesionales sin ir al salón. Lo volvería a comprar.”*

Amazing results. My daughter has really thick hair. It's thinned it out and isn't frizzy. Much more manageable. I will buy this again

Bottle came opened.

I received the product in good condition. The seller did his / her best to seal the container. This is because there is no internal seal, which I found it weird. At last I got the time to try it and I followed the instructions. Barely minimal change in the color of my hair happened (dark hair) which I am very happy. No rusty colors at all. It worked well and I am happy for the result. Thanks to the seller and Amazon staff who did their best to deliver it safe and sound.

The Bio Protein Hair Treatment from Expert Hair Store is one of the better formaldehyde-free keratin products available. It delivers noticeably smoother, softer, and shinier hair while controlling frizz even in humid conditions. The texture is creamy and spreads easily through the hair, making it simple to apply without feeling greasy or heavy. It also has a pleasant, light scent and does not produce the harsh fumes that come with many chemical straighteners. A major advantage of this treatment is that it’s safe and gentle on hair because it’s made with natural ingredients like coconut oil, shea butter, and rice protein. These add hydration and strength, helping repair damage while keeping the hair sleek and manageable. However, one thing to be careful about is that some users notice their hair can feel slightly dry or brittle after frequent use, especially if heat is applied too often. It’s best to follow up with a moisturizing mask or oil afterward to keep your hair balanced. Overall, the Bio Protein Hair Treatment gives salon-level results without the strong chemicals. It’s an effective, easy-to-use option for anyone looking to straighten and smooth their hair safely while keeping it shiny and healthy.

It came perfectly sealed! I was worried from the previous reviews but looks like they solved that problem!!!
