GK HAIRGlobal Keratin The Best Consumer Box Kit (10.1 Fl Oz/300ml) Smoothing Keratin Treatment Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizzy Hair

Used this today. I followed the very clear, concise directions and I love it. Having had keratin many times before today one of my favorite things was washing my hair right away. No more feeling like my hair was weighed down with funky keratin.I will use it again when necessary.

Product is great. Keep in mind it's a smoothing treatment. If you sweat alot you will have to touch roots about a month earlier. I have combo hair 4a, 4b. Keratin usually gets my hair to a 3c. If hair gets wet a quick blow dryer puts it straight again.

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.

Love this product I did a diy with my daughters hair and it came out like professionals will buy again and still have left over

I have THICK, naturally wavy hair. In warm humid conditions it can become unruly. My routine when I wash it is to dry it, use my flat iron to smooth and straighten and then a big rod to add some curls to style. It is a process!There were mixed reviews in this product. To clear one thing up - follow the directions on the box. Leave the product in your hair and then rinse out. No one would want to blow dry their hair with this product on their hair! Rinse then blow dry and straighten.The end result has allowed me to eliminate my smoothing iron step as my air is less frizzy and much smoother and it dries more quickly. I’m looking forward to seeing how long this lasts, but will purchase and do again.For my hair, I had to use the entire bottle of product. The only reason for not giving maximum stars is due to the smell. It’s tolerable, but now I’ve washed three times post processing and the smell still lingers, but I will take that over the work of straightening each wash.

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 received my product but with no instructions to apply from home. I can update this review if I can find the full introduction on how to apply it step by step. Please Help!

We've used all types of keratin treatments for my daughter's thick, coarse, wavy hair and had high hopes for this one. We followed the instructions to the letter. We were disappointed.The Pros:Easy to use, less steps and smells much better than other keratin treatments.The Cons:Minimal results that don't last at all. After just one wash, the hair is right back to where it was prior to treatment. Not worth the time and money.
