I have 4b/c hair. I was hesitant to purchase, but read the review from another 4 tenured lady here and saw a review on YouTube from another. I have also had salon keratin treatments in the past. People need to understand that this is NOT A STRAIGHTENER. It’s a smoothing treatment that helps with frizz and manageability. And to that point, I am VERY happy with my results. There is no horrible smell or fumes like the salon version. It didn’t burn at all and I found it easy to use overall. My kit had all the advertised pieces. The shower cap is a little small and the gloves aren’t the best, but fortunately, I had extras of those items on hand. I had great results immediately and my hair stayed straight for 2 weeks in Texas heat and humidity until I washed it. My hair reverted after the shampooing but was much easier to handle and manipulate than before the treatment. After the first wash, I conditioned, dried, and flat ironed (only 1-2 passes this time) and it stayed straight again. I’ll see how long it lasts. So far my hair seems like it’s still healthy and non-damaged. I’ll try to update this review if there are any significant changes.

The results are amazing. I normally have frizzy wavy hair and for 6 weeks I got really straight shiny hair and now I'm at 10 weeks, and although it's not pin straight, it still looks very good and tamed . I would definitely recommend this product. I applied this on 80% dry hair, and then I left it on for about 40 minutes, then dried it, then straightened it piece by piece, though I straightened it in relatively bigger pieces, I would say the straightening part took me about 50 minutes, and I have quite long hair. I didn't wash it immediately, just in case. I kept it on for a bit longer than 24 hours then I washed it. It felt really heavy during those 24 hours though .

I purchased the GK HAIR Global Keratin "The Best" Smoothing Keratin Treatment Kit with high hopes, expecting a significant reduction in frizz and smoother, straighter hair. While the product was easy to apply and came with clear instructions, the final results did not meet expectations. Despite meticulously following the recommended steps, including processing time and aftercare, the treatment did not produce a noticeable difference in texture or manageability. My hair remained prone to frizz, and the promised smoothness was minimal. Given the brand’s reputation and the investment in this kit, I anticipated more effective results. To improve the experience, GK HAIR could provide more detailed guidance on how to maximize results for different hair types. Additionally, adjusting the formula to better deliver on its claims of lasting smoothness would make it more reliable. For those considering a keratin treatment, I would recommend researching alternatives with consistently positive reviews. Overall, while the packaging and instructions were well-done, the effectiveness of the treatment did not justify the price. A more reliable formula would make this a worthwhile investment.

This is a fantastic product. My hair has never felt so good. I used to relax my hair and also used japanese hair straightener for while, all of which were very damaging. This product does not have a smell like other relaxers and keratin treatments. It's so gentle and smells good. I was shocked how well it worked. My hair is soft and manageable now. Although I was not intending to take all the curl out, it did straighten my hair. It looks fantastic.

I did this keratin treatment myself at home, very carefully and step by step, and the results came out exactly the same as when I used to get it done at the salon with the same brand. The hair becomes smooth, shiny, and straight — just like a professional treatment. However, you should know that this keratin does pull color, especially if your hair is freshly dyed. My hair was dyed black, and after the treatment it turned into a light brown. So if your hair is dark, keep this in mind. Also, after the first wash, the hair can feel a bit dry, so I recommend using a light serum — preferably from the same brand or any serum that is free of ammonia and sulfates. This really helps bring the moisture and shine back, especially in the first few days. Overall, amazing results, just follow the steps carefully and be aware of the color fading.

The keratin product is decent - I followed the instructions but then didn’t shampoo it right after (waited 48 hours like I’ve always been told at salons). It seems to initially work almost as well as some salon treatments I’ve had (which cost between $180 and $250). I also only did one treatment so far and didn’t even use half the product (and I have hair that goes down to my shoulder blades and is moderately thick). My main complaint is the smell when you wash it! I’ve washed my hair a few times since then and the smell still lingers. Another review said it smelled like fishy hot dog water - I’d say that or a wet dog. I had good results for about 3-4 weeks, and then my hair was almost back to its original state. Bottom line - results were good but only lasted a few weeks as opposed to a professional treatment that can last a few months.
