Global Keratin The Best Kit 300 ml Smoothing Keratin Hair Treatment Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizz Free Hair

I like this product because zero formaldehyde which is carcinogens. I was doubting it will straight my curly hair. My hair is too much curly. It straightened my hair by almost 80 percent which is good. Recommend for curly hair . A salon put for me which is v important because they can apply on each section blow iron is also important.

I am waiting to return the product as the best bottle(2) is unsealed and used before or changed with fake one. Also the sealed color is different than the other items color.

I cant express how happy i am to have found this product finally something that works and is not as toxic as the other brands. Dont waste ur money on other stuff if u follow the instructions it works 100% only thing is it doest come with kit items as on the pic no gloves or cap or plate just the product tubes and a brochure.

سهل الاستخدام

Good

Bottle no 2, actual treatment, was only one without protective cap so seller probably opened and added water, it was pretty runny, not like on the video.

I didn’t receive the deep conditioner

Very good

Jättebra tack så mycket

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.

There are some mixed reviews on here which caused me to hesitate prior to purchasing this product, but I'm soo glad I did. This is the same treatment my hair stylist uses and the results were actually better than when I go to the salon because... I follwed the instructions! For reference, I have type 4a/b hair, fine strands and eczema on the scalp. A couple things to note: First, avoid getting the Best product on your scalp. At the salon, I got scalp burns because my stylist applied it like a conditioner. Doing it at home, I had a friend help me and applied it like a perm--section by section, focusing on the hair (like they show in the instructions) and I was completely fine, not even a tingle! Second, this is a smoothing treatment. On my hair, it primarily reduced the amount of "kink" in my texture, and left me with more elongated curls. It did not straighten my hair but, it does make my hair super easy to blow out and straighten (I mostly wear my hair straight). Also, I know from previous experience that my hair will revert to its normal kinky curly texture after around 5 months. Third, the Best bottle that comes in the pack is 100ml. I was worried this wouldn't be enough as I have alot of hair, but it was. I needed to use the entire bottle though (and brushed through each section with a denman brush) to ensure my hair was completely saturated. Overall key take away here: I loved the product, my hair looks and feels absolutely amazing. Already bought another bottle of the Best to have on hand for when I need it again in 5 months! Totally worth it!

I loved this set I used to use the old gk the one with the strawberry and chocolate ( for curly hair) This one is a bit lighter and doesn't last like the old one but still better then every other option here ! One product came wrong and they kept the product to me and sent me the correct one ! So amazing customer service as well :)

I am a hairstylist in Japan, and when I followed the procedure described on the official website, this product worked perfectly. If it does not work, it is possible that the amount of the Best applied is too little or that the temperature during the 40–60 minute processing time is too low. Review the application amount and either increase the room temperature during processing or use a warmer cap.
