GK HAIR Global Keratin ACAI Smoothing Keratin Treatment (33.8 Fl Oz/1000ml) - Professional Brazilian Blowout for Frizz-Free, Silky Smooth Hair | Salon-Quality At-Home Straightening Solution for Damaged & Curly Hair

I am Black with a mixture of 3C/4A hair. Some of you are trying to see how this works on black hair so here is a review for my people. IYKYK... For the record, I don't really believe in curly hair types because my hair pattern becomes more kinky when dry and is curly/coily when properly moisturized. I'm mentioning it here as a reference point for the girlies. Again, IYKYK.I like this product. I've tried plenty of things to help my super dry natural hair and NOTHING really helped. My hair continued to remain dry. I know natural hair needs moisture to cooperate & I KNOW how manageable my hair is when it's properly moistured (my first henna treatment showed me that years ago). Well the instructions were simple and straightforward. I didn't notice any bad smell like some other reviewers and I couldn't have cared less what it smelled like if it worked. It was VERY easy to use so the girlies who struggled, must be struggling in life because a relaxer at home coloring is way more complicated than this. I purchased the revlon blower dryer (Dr. Curly or tangle something) brush to assist with blow drying process which made everything SUPER easy. I also combined it with an olaplex treatment but I don't feel if affected my results at all.Truthfully, what really helped, was when I washed my hair a week later. I used the Aphoghee shampoo & moisture balancing conditioner. I didn't do another olaplex treatment, just the Aphoghee and my curls were Chris Brown Poppin! My natural hair was super manageable and my entire head was 4C for reference. I know my hair is thoroughly moisturized and behaving when I don't have to drown it in product. I can spray it with some water, a little leave in (my hair is fine so I do mean a little) and a bit of Aussie curl gel (the only gel I use because it's mositurizing and mixes well with ALL my hair products. You ladies know ecostyler doesn't mesh with everything, but the Aussie Moist gel does!The product does appear to loosen your curls a bit, but I believe it just really moisturizes the hair more than a looser curl pattern. Again, I think really moisturized hair makes a difference in your curl pattern. I only noticed my new growth because it was super frizzy and very tightly curled compared to the the keratin treated hair. I did my treatment early February and it is mid-April. I noticed about 2-2.5" of new growth and the treatment is still going strong.I'm unsure if it permanently straightens hair after repeated treatments but my next application will probably be over the untreated hair first. This is not like a relaxer/texturizer. My hair is still very curly; it truly is more just manageable than before. However, eventually, I will try to see if it straightens hair with repeated applications or it only lasts so many treatments before it reverts back to my natural hair. As long as the treated hair cooperates, I don't see an immediate needs to reapply the treatment of the pre-treated section.I apologize that this review is long, but I wanted to give as much details from my perspective because I know I didn't have much to work with from a Black woman's perspective when I was unsure about ordering this.
