  • Great affordable straightening option for men with curly short hair
I have had very frizzy/curly blonde hair since I was young. I now have short hair, slightly over an inch long on the top. I like to blow dry my hair to style it into shape. I have been using this treatment for 2+ years now, about every 4-6 weeks. Without this keratin treatment I can't really shape my hair at all. Blowdryers don't create shape that holds and flatirons make my hair awkwardly bone straight. Pros of this product: - Result is great for 3-4 weeks and makes my hair so much faster and easier to style with a round brush. This saves me so much time fighting with my hairspray and comb to get the front of my hair to look nice. - Very quick to apply on men's short hair (takes me like 5-7 mins to comb through). - Can wash out next day, don't need to wait 3 days like common salon products. I usually try to wash out after 12 hours, but have waited as little as 8 hours before too. Cons: - Once your roots grow out with short hair, it becomes much harder to style. So I do have to re-do this process about once monthly. That's not the product's fault, but worth calling out for men with short hair considering this. I think the net time savings though every morning is worth the 45-60 mins this takes me monthly. - To get the best results, you'll want to buy a skinny straightener specifically designed for men with short hair. That enables you to get down to the root of your hair when you straighten it during the treatment. There are plenty of affordable options on Amazon. - The smell is chemically, but honestly not that bad. - The fumes do irritate my eyes. But it's not unbearable. Having a fan is a game changer. Merely cracking the window doesn't really reduce the irritation. Overall I very much recommend this product to men with curly hair who want the ability to shape their hair more. Love the way my hair looks, especially the first couple weeks after I do the treatment. ... show more

  • Follow directions!
Size: 120ml (Pack of 1) Standard Formula
Years ago, I had use Ion's Smoothing system. It worked pretty good. The idea of blowing my hair dry and straightening it without product was scary so I decided against the manufacturer's directions to use my own products for the blow dry and flat iron processing. My results were still pretty good. A year ago I started to notice that my relaxed hair was showing really bad damage around the hairline kind of crunchy, kind of thin, and I was concerned, so I decided to begin taking supplements suchbas liquid collagen, biotin and sawgrass. About 6 months ago, I began applying batana oil. These seemed to be working, but yhe results weren't 100% yet. I decided to go back to keratin. I chose this system because I couldn't find the Ion Smoothing System. I followed the directions and my results were really good. I used an oblong hair dryer for the blow dry. Then I used a ceramic heat brush as I sectioned my hair. Before flat ironing each section in 1/8 increments, I combed it out with a hot comb. I also used a pencil flat iron for the areas around my hairline (this was the final step that really made everything stand out). I did not use any other products until I finished the processing. I wrap my hair and for the week after initial processing and make sure that it didn't get a drop of water in order to maintain the look. Now I don't even need to flat iron it ... blowing it is fine. Using hot curlers versus a curling iron also gives a more polished look. FYI, I dye my white Grey hair Tiger Brown using Herbb shampoo ... show more

  • Excellent At Home Keratin Treatment!
Size: 120ml (Pack of 1) Standard Formula
Oh I wish I could add a before and after picture! Went from frizzy to smooth in one treatment! I used this Original Formula Keratin tx after shampooing with the clarifying shampoo the night before-yup I'm that lazy I let it airdry overnight, I didn't want to blowdry my long hair twice...Anyway, the next day: took my time, applied the easy method (with my fingertips), combing out any excess with a fine tooth comb, followed directions: cover with plastic for 30 min, blowdry 100% and flat ironin small sections: and WOW-looks like I went to the salon! I am soooo impressed with this product. Does it smell like keratin, yep, so use in well ventilated room. I suggest using less is more (because you leave product in hair and have to dry it 100% before flat ironing), I used about 1.5 oz of product and my hair is long, med fine, with uneven wave/curl pattern at nape and back of head especially: so I sectioned and made sure I straightened those areas most since they are hard to reach and my problem areas. And with this Florida temps being both hot and humid, my hair was a frizzy, hot mess-not anymore!!! I now LOVE my hair after this treatment: Smooth, Straight, Sleek! Super product: 5 stars+ ... show more

  • Very toxic! DO NOT USE. HAVE ME CHEMICAL BURNS!
These pictures were taken on the 2nd day when the burns were already improving. This product is horrible. I knew something wasn't right when I saw that the shampoo in the box was MK (Morrocan Keratine) and they were both probably made by the same company. I used MK keratin a few years ago and it smelled horrible and destroyed my hair. This time, this product burned my ears and neck even though I applied it as directed in the box. My skin rarely gets irritated by something, so then I went to see the ingredients and discovered that it has so many carcinogens and substances that nobody should allow near them. I regret using this and I hope people stop putting these chemicals on their heads! ... show more
