    • Worked on my 4b/c hair
Style: 400ml
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. ... show more

    • NOT worth the money AND Terrible customer service!!
Style: Consumer Box 100ml
I followed the exact directions, step by step and even though my hair felt great right after the treatment, after the 1st wash (using the included shampoo+conditioner), my hair went back to almost the same texture as before. It was still frizzy and curly-ish. It had a slighter smoother texture, that’s all- DEFINITELY Not worth the money. Also the after-smell of the treatment is just awful! It’s so bad I have tried to get rid off it during the last few washes by using different shampoos/conditioners that smell good, but I can still smell it, especially when is wet. I would not recommend this - I would just go to a professional salon next time and pay the extra$ for a good product, labor, and the long time it takes to apply a keratin treatment. UPDATE: the company contacted me to ask me which steps I followed. I explained to them that I followed the exact steps listed in the instructions, EVERY SINGLE ONE. They messaged me another 2 times inquiring about the iron temperature I used, and other specific questions, to which I answered. then they emailed me again to tell me They don’t believe I followed the proper steps!! This is THE WORST CUSTOMER SERVICE I’ve ever had! If you are going to email your customers to ask if you followed their instructions (which I very carefully did) and then tell them you don’t believe them you shouldn’t even be in business! I 100% WASTED 100$ and also the ton time I spent applying the product AND answering their pointless messages. IF I COULD GIVE THEM NEGATIVE STARTS I WOULD!!! ... show more

    • Great treatment, bad clarifying shampoo
Style: Consumer Box 300ml
I love the hair treatment, but I follow the alternative instructions so my hair actually stays frizz free and straight for 5 months, BUT if you dye your hair 100% stay away from the best ph+ clarifying shampoo. It will oxidize colored hair instantly. Use a different one. You're welcome.

It didn’t do anything to my hair. I have 4B to 4C hair. It smells nice though but I won’t purchase again.

    • Love
Style: Consumer Box 300ml
I have my hair done twice a year at the salon for $500 each visit and this is the same product. Tried it by myself and loved. Worked for about 3 to 4 months. Saved $400 plus I only need to buy the straightener for $25 each time now because I have plenty of this product left for many more treatments.
