  • 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

  • Works so well
Size: 120ml (Pack of 1) Standard Formula
Even though I color my hair myself, I was initially nervous to try to straighten my hair. It was much easier than I thought, and it definitely does take 2 - 3 hours from beginning to end. Not only does my hair look great and it's so easy to take care of now, but it's so soft too. I've become one of those females who's always playing with her hair... but I can't help it! ... show more

  • Dangerous
I don’t know ? does seller try product before launch in the market or not but . I must suggest before selling any such product tried on your own . I bought this product . no doubt I check review before . I thought every hair product has some chemical specially in hair straightening . But this product attract by mention that it has some oils in it. I thought that must be good and not harmful at all . When it came I opened and smelled . First doesn’t smell strong . I thought it’s good to apply and leave for 3 days as per directions but when I applied . It hurt my eyes and nose really bad couldn’t breath . I must say this is completely harmful for eyes and health . If someone face any serous eye problem then would no doubt because this product . I would strictly not recommend to anyone to buy this product and put your health and eyes in risk . I regret to use that . I want my money back . My eyes still burning . I also want to mention here . I had to do just touch up for new growth . Not from the roots obviously . I done my hair straighten last year . I used their shampoo as it was recommended and just one wash it turned my whole hair into curl . I had no choice left to use their product and this shampoo also made dandruff just in one wash like I flour in my hair. Really bad experience surprising thing you can give ur review without rating star . This product doesn’t deserve even one star. ... show more

  • Worked Well on My Tight Curls
Size: 120ml (Pack of 4) Standard Formula
I used this keratin product last year, and overall it worked pretty well for me. I have really tight curls, and it definitely made my hair straighter and easier to manage, especially when I did a sew-in. It didn’t get my hair bone-straight (which makes sense given my curl pattern), but it still did its job and made a big difference. One thing to note: the smell is very strong. I highly recommend applying it in a well-ventilated area or somewhere with windows open, because the scent lingers for a day or two. Also, you have to leave it in overnight for the best results. I’ll admit I was a little impatient, which might be why I didn’t get the maximum outcome. That said, for the price and purpose, it’s a good product if you’re looking for something to help loosen curls and make straight styles last longer. ... show more
