Expert Hair Keratin Smooth Botox for Hair, Anti-Frizz, Natural Look, Queratina para Alisar el Cabello, Thermo-Active, Suitable for All Hair Types (1kg/35.3 oz.)

I have brittle, impossible to straighten hair. I have had Keratin treatments and other various kinds of straighteners. They don't work...a salon visit, following by hours of time and days without showering. I tried this at home yesterday. It's been in my closet for 3 months as I was afraid to use this at home. It worked! My hair is soft, so far no breakage. Not perfectly straight but MUCH easier to style and 75% straighter.-I washed with clarifying shampoo-I used gloves and applied a lot of product-I put on a shower cap and left the product on for 90 minutes-rinsed 70% off blow dried-Flat iron on 400-Washed with conditioner and dried. It was so easy.-A week later still straight I am a fanIN the end it was far cheaper and easier and worked better than salon. If you have unruly hair try it!

Amazing products. I have terrible frizzy hair. I am so glad I came actually this product. Easy to use. I washed my hair with shampoo then I let it air dry. Then I applied the keratin and left it on for an hour. I rinsed about 70% out of it and then I blew dry it and I used flat iron going over sections about five or six times. The first picture is my hair after I shampoo washed it. The second picture is right after the treatment and the third picture is what it looks like after washing my hair and blow drying it after the treatment. I waited 3 days between the treatment and washing my hair again.

I can’t begin to explain how much moisture this brought to my hair. I applied it at home a month an a half ago. First pic is my natural hair, second pic after application, blow dry and flat iron. Third pic, a month later, only blow dry. I would recommend to trim your ends before applying it. My hair is still curly when wet. Also I think it clarifies my hair a little. No issues with hair breaking or falling. Even the 2 or 3 gray hairs I have are shining. It is a very large bottle that can serve for multiple applications. Would definitely buy again.

Not worth to buy

I have been getting keratin treatment since it came out, that’s a long time. . When the stylist irons my hair there is always a little breakage. And then at home I notice breakage continue. I have thick, coarse, Persian hair. It’s so thick that I’ve heard stylists say they’ve never seen such thick hair. That being said, this product was easy to use, result was excellent and I have ZERO breakage. It’s much faster to straighten than ever before, I usually have to do multiple passes with my Dyson iron, but now one pass is sufficient. So that means faster and less damage. Pleasantly surprised that I’m getting a better result than the professionals. And I’m ecstatic to save the $.

This product has truly transformed my hair! It's an organic keratin treatment that's formaldehyde-free, and I’ve used it a couple of times now. Each time, it makes my hair so much more manageable, soft, and frizz-free.I used a clarifying shampoo twice, let my hair air-dry a bit, then applied the treatment and left it on for about an hour. Before blow drying, I wiped off some of the excess product, then flat ironed my hair in sections. My hair felt stiff while blow drying and the flat iron didn’t glide as easily with all the product in it—so next time, I plan to rinse out more of it before styling, like some reviewers recommend.I washed my hair three days later and it was noticeably smoother, straighter, and completely frizz-free. Not pin-straight—which I actually loved—since I prefer a bit of natural wave. The results lasted about four months before I noticed frizz coming back at the roots.I’ve had salon keratin treatments before, and while they worked, they left my hair feeling thinner and cost way more than this. This one is affordable, non-toxic, and gives me great results without making my hair limp. I’ll definitely keep using it every 4–6 months.The only reason I took off a star is because my teenage daughter didn’t love the results. Her hair is much curlier than mine, and it made her ends look straighter than the rest of her hair. I’m not sure why that happened—it could just be that the difference was more noticeable on her tighter curl pattern.Overall, I highly recommend this if you’re looking for a formaldehyde-free keratin treatment that actually works and leaves your hair soft, manageable, and healthy-looking.

The media could not be loaded. I recommend it, I loved it, it leaves my hair soft and fragrant.

…Do not follow the instructions on the back of the bottle. I did the first time and my hair looked so dry and brittle afterwards. I tried again after reading some reviews. I followed one in particular (thank you to that person!). Here is what worked….I washed my hair with clarifying shampoo—twice. I fully dried my hair. I sectioned my hair in parts and applied the keratin with a brush applicator that I typically use for hair dye. I left it on for 50 minutes. I washed off about 70 percent (which is just a guess because I really don’t know). I then dried my hair thoroughly and sectioned it again. I flat ironed on 410 degrees in small sections. I passed the flat iron through 6-8 times for each strand. This time it worked much better! I love it now! My hair is naturally curly, dry, thick and coarse. So even though it’s not the shiniest, for me it’s definitely a win. It makes drying easier/ faster and overall more manageable.
