GK HAIR Global Keratin The Best Smoothing Keratin Treatment Kit (3.4 Fl Oz/100ml) Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizzy Hair

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.

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’ve used this GK Hair Keratin Treatment kit on my fine, slightly wavy hair, and I’m really satisfied with the results. The formula is truly gentle — no strong smell, no burning, and most importantly, it didn’t cause any irritation to my scalp or hands during application.It’s a great fit for hair that’s not too thick or too curly, and the 100ml size was just enough for my shoulder-length hair. I noticed a visible improvement in smoothness and manageability after use.Also, it’s free of formaldehyde and sulfates, which makes it a safer choice compared to many other treatments. Highly recommend if you’re looking for something effective but not too

The keratin treatment works fabulous. I'm someone that has had numerous Brazilian blowouts but they changed the formula and it dried my hair so decided to give this a try. The clarifying shampoo works great and leaves hair squeaky clean without over drying hair. The keratin treatment leaves hair soft, shiny and frizz free. Saving so much by doing this myself. Beware the regular shampoo and conditioner smell super awful that's why i gave it a 4 star I wish i could return them but bought the set. I would recommend the ph shampoo and treatment only. The treatment itself smells fine to me. I was not bothered by the smell out all. Loved results. Will continue to purchase if the treatment lasts.

GK hair treatmentDespises de leer los reviews, compré el producto. Las instrucciones están claras, pero el resultado no fue el mejor. Mi pelo quedó muy reseco.

I love this and i will be using this keratin now and then.!

This GK Keratin treatment did NOT deliver and cost extra money for emergency color correction (which will require multiple sessions to fully repair). My base color and highlights changed from ashy blonde to Brassy/orange. I followed all directions and want to emphasize that I have years of experience with multi-step keratin processes, including a Global Keratin product for in-salon application. But, In a side by side comparison we found the 'Best solution' is NOT the same name or formula used by my stylist. I also saw little difference in hair texture or humidity resistance making this a complete waste of money and time. Instead, try Color WOW extra strength for easy application, better results per wash and style, and no risk.
