Review: Best hair purchase I've ever made! - I have hair down past my bra clasp, a majority 3B curls with some 2A randomly mixed in and I hate it because my curls are really disorganized. I have straightened it basically every day since I was young, which is about an hour of blow drying followed up with a straightener. Huge pain in the butt time-waster. Due to a sharp increase in workload this semester, I decided I needed a more permanent solution because still I need to look professional at work. I can't look like I've just given up, people! Anyway, I researched keratin treatments (all summer ya'll, all summer) and purchased the 120 ml bottle after reading all the reviews. After doing the treatment, I shampooed with sulfate free shampoo and conditioner and decided to test it out by just letting it air dry (I've always dreamed of doing this). I AM AMAZED! My hair is silky smooth and completely straight! Zero effort required! I literally wanted to cry tears of joy. It's been a couple of weeks and it is still perfect so I have hopes that this will last for the 3 months. For anyone interested, I did not have the patience to follow all of the directions and instead did what was recommended by another reviewer (slightly modified for laziness/impatience): 1. Shampooed (X2) with my dish soap to get all the oil and product out. I didn't feel like ordering a clarifying shampoo, ain't nobody got time for that. No conditioner or products after clarifying. 2. Comb (carefully!) with wide-tooth comb. Let hair air dry. Yeah it looked crazy. 3. A few hours later I applied the treatment all over with a dye brush and combed out the excess. I've been dyeing my hair at home for years but if you don't have practice with that you may want a friend to help that you don't mind seeing you topless. Or wear a towel. Whatever. 4. Blow dry completely. Your hair is gonna feel really bad at this point. Power through. 5. Make sure it is COMPLETELY dry and then flat iron it like you've never flat-ironed before. Go to town, get the roots, make several passes, use a comb, be serious. Torture your hair because it is the LAST time you're going to have to for a very long time (yay!). 6. I think I sat around for like an hour before I finally said forget it, there's no reason to wait, I've heat sealed this stuff and my head has cooled off. Look, I have really nice sheets and I couldn't fathom sleeping with a towel on my head to protect them, ok? Stop judging me. 7. Shampooed and conditioned with sulfate free and Voila! You already read the amazing results. This product is a godsend and I will be ordering it for the rest of my life. One drawback (not the product's fault) that I hadn't thought about it that if I let it air dry, it's pretty flat. I'm not complaining because straight is what I wanted and I can still put any kind of curl in it with a curling iron. However, I have started hitting my roots with a blow dryer for some volume and it works perfectly and takes maybe 5 minutes. Then let the rest air dry. BOOM, this stuff is gold. I just threw out tons and tons of hair products and cleared off my bathroom sink. There's so much room for activities now! Glorious. **UPDATE: I did this treatment in late Aug 2017. It is now the middle of January 2018 and I am about to do another treatment because my roots have grown out quite a bit and are starting to get wavy. It lasted over 4.5 months perfectly. Highly recommend this product.
Review: Love the End Result - I am not much for writing reviews, but since I rely on reviews when I am trying to decide whether to buy something or not, I thought I would provide my experience with this product which I used for the first time today. Now, my hair is frizzy, kinky curly and definitely hard to management, especially in Florida's heat and humidity. I think in my life time (I'm 56) I have had more bad hair days than good. So, I am no stranger to methods of straightening my hair. I had my first keratin treatment several years ago and before that I had the Japanese Hair Straightening which has its own drawbacks, but shelling out $250 or more on any regular basis is just not in the budget. Previously, I was using Bio Ionic Agave Smoothing System. It is the same process, washing with clarifying shampoo, blow drying hair, putting on the treatment, leaving it on for 30 minutes, blow drying it in, and then flat ironing it. Then you need to let the hair cool for about 20 minutes, and then you need to shampoo hair again (with a sulfate free shampoo), condition and blow dry and flat iron hair again. Plus, if you had hair color in your hair, this product does lighten it quite a bit, and if you wanted to color your hair you have to do it right after the last step, otherwise you needed to wait a week. Needless to say I would spend a lot of time doing this, and the end result was just okay. The Agave product had a caramel scent to it, and you did not need a mask while applying it or anything, but the scent kind of stayed with you and that part I did not like. So, after using the Agave for over 3 years I wanted to try something else. So, I started to look for another product and of course I came to desertcart to start my search. After reading the other reviews, I decided to give this a try. I was a little nervous at first because I think this product is stronger than what I was using previously. I read where people wrote that it made their eyes water and to make sure to do this procedure in a well ventilated area. The problem is that I live in a really small apartment that does not have good air flow. I turned on all the ceiling fans and the bathroom fan along with a stand up fan that I had. When I needed to blow dry the product into my hair, I sat by the sliding glass door with the fan blowing on me so the fumes would go outside. This product did make my eyes water and I am not used to wearing a face mask, so I did have a little bit of a problem with that, but I was able to get through it rather quickly. When it was time to flat iron my hair, I did it by the door as well and overall there did not seem to be a lot of fumes. I am not sure if this was because I was mindful of the amount of the product I had put in my hair, or I just did not notice it. I bought the smaller bottle (4 ounces) just in case I did not like it, and only used 2 ounces for my shoulder length hair. The first thing I really loved about this product is that it did not strip my hair color so compared to the product I was using previously. Since the it had extra steps that needed to be done, I would easily spend 4 hours with the whole process. With this keratin treatment, it took me only about 2 hours. This product left my hair really smooth, and I have not noticed any type of scent. I liked the idea that I could wash it relatively quickly after the treatment, and I thought that I would be washing my tomorrow, but I did not feel that it will be necessary. The only thing I would suggest is that if you have never had a keratin treatment before and want to try doing one on your own, to have someone with you to help you with the process.

### ⭐⭐⭐⭐ Great Alternative for African American Hair...
*by M***A on December 27, 2012*

As I use this product I take caution and advise anyone who wishes to purchase this product to research what formaldehyde is. The only issue I have is the labeling of ingrediants and amount of Formaldehyde to which this product contains. This product works very well on african american hair, I would certainly advise anyone who is seeking an alternative to perms/ relaxers to give this product a try however I advise with caution. I have 4b- 4a curls (google it) and my curls have stretch to around a 3b- 3c (google it) pattern. My hair reponds very quickly to flat irons. The fumes are very concentrated and the product warns for the user to avoid inhalation of the product which is unavoidable if your doing it your self. I would suggest using this product outside if able to, and have someone do it for you just to be sure that the product is evenly distributed. I will see how long this product lasts me and give an update comment on my results. I am looking foward to it lasting 4-6 months because of my curl pattern, I will let you know. Also prevents my hair from frizzing up in humid wheather (live in florida) . My hair is very light and movable with a lot of body and a lot of shine. The only reason I purchased this product knowing that it contained formaldehyde is because I am using it on a small section of my hair (leave out section) and will only use this product every 6 months.
