GK HAIR Global Keratin The Best Kit (33.8 Fl Oz/1000ml) Smoothing Keratin Hair Treatment Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizz Free Hair

Amazing product nanoplastia elevated from the keratin hair is smooth brighter and softer great for curly, wild or Afro hair this does the trick and this package has the sulfate free shampoo and conditioner too

In all honesty say this product doesn't work. My hair was soft but still very curly and frizzy, I contacted GK, but all I got back was do the procedure again, which I did 3 times but still the same. I have no product left, a waste of money. I used to be a hairdresser so I know how to do these procedures.

I remained very pleased.

After using another product for 4 years it was discontinued by my usual suppliers and became nigh on impossible to purchase here in the UK. I did some research on formaldehyde free keratin smoothing treatments and this one was number 6 from a list of the top 15. It's very easy to apply. The instructions were easy to understand and straightforward. Wonderful results, I shall definitely buy this product again. It's unbelievably better than the original product I used. My hair feels silky and smells great!

I almost retuned this as the No 2 the best cream seemed half empty but unfortunatley misse dthe return window. Hence I used it this week and result is great. You xan notbget salon quality at home doingbit yourself but almost simikar result. Would recommned . This is one of the best keratin treatments.

I haven't use the product yet, but I it didn't come with all the other items like it is shown in the advertising/ picture. That is gloves, bowl etc..

I used this on my hair. My hair condition is dry and damaged. It came out really nice and de-frizzed my natural frizzy curly hair. The instructions were straightforward and enough product for my medium length hair with some product left over. Excellent quality product and will use this again. A bit pricey but well worth it.

I feel like I’ve been scammed. This is a honest review .Doesn’t work at all. I’ve flat ironed my hair after first two washes and thought this will long last. But if you don’t flat iron after each wash, then your hair is just like wavy normal look. This is a waste of money. I want to report this. Don’t ever think of buying.

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 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!

Great

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 :)
