Kerazon ProfessionalBrazilian Keratin Treatment 34fl.oz/1L Tratamiento de Keratina Brasilera Importada KIT w/ pumps Buriti Liss by KERAZON

TLDR Version: My hair is long, thick, and 'crinkly'. This is my second time using this product and the results are awesome and long-lasting. Use in a WELL ventilated room. You won't think the product smells bad at first, and it doesn't. But then it hits you and there is no excape. If it gets really bad, so outside for a few minutes and let your space air out. I used about 3/4 of the shampoo (washed twice), the entire 4 oz bottle of treatment, and the entire bottle of hair mask. If your hair is longer than mine you may want to get two sets. Tip: Do NOT wash your hair for 3 days after the treatment and use a quality Keratin-treatment specialized shampoo when you do. Using regular shampoo immediately after the treatment will cancel all your hard work and you won't get great results.Long version: If you have hair like mine, you know it's a struggle to manage. From fly-aways to frizz to always looking like a hot mess, I understand the pain. Flat ironing helps but who has time for all that? I dreamed of being able to "wash and go". Salon options were out of reach because of cost and time, so I tried this home option without expecting much.I first used this product in March of 2022 and OMG, I had incredible results. The process took FOREVER - from blow drying my freshly washed mop to brushing on the treatment to blow drying it again using the cold setting to flat ironing every strand. My arms were jelly, my nose was runny, my eyes were tearing - but I had beautiful, straight, and flowing hair. The treatment lasted well over 9 months; after that I started to notice more and more frizz returning and my hair started to tangle more. Time to set aside a day to do it again but I did it a little smarter this time around.After washing my hair with the shampoo, which basically strips it down to a rats nest of straw, I let it air dry until it was damp but not completely dry. The first photo is what my hair looked like after the wash. I then parted my hair into 8 sections (which was difficult to do being that my hair was extremely tangled) and using gloves, dumped the treatment into a bowl and used my fingers to spread it through each section, followed by the comb to make sure each strand was covered. So much quicker!The instructions say to use a blow dryer on a cold setting to dry the hair. Um, hello? It took me a good 2 hours to get my hair dry last time. Cold air + long, thick hair = HAHAHAHA, nope. This time around I planned in advance - I let it air dry as I worked (desk job, work from home). This might not be an option for you so plan on spending half the day watching TV or whatever takes up 5-6 hours.For the flat ironing, I did it per usual. I don't have expensive flat irons; mine are 1" and 2" Remmington brands from Walmart that I've had forever. They only go up to 430 degrees so that's what I used, going over each little section multiple times. Your hair will get VERY hot and smoke a little as you flatten your hair into submission. Although the instructions say that there is no wait time before rinsing, I did wait about 15 minutes.I rinsed the treatment out of my hair and applied half the bottle of the hair mask, brushing it through with a comb. Then I applied the rest of the bottle by working it through with my fingers; wrapped my hair in a towel, and rinsed again an hour later. You can rinse it out after 5 minutes but I had a conference call and decided to wait. After rinsing, I towel dried my hair, combed it, and let it air dry again. The second photo is it fully dry - no product, no flat iron, nothing. Exactly how it looked and felt last time I used this product.Now the 3-day timer begins - the instructions don't say this but it's best to wait at least 72 hours before getting your hair wet (even sweat) or washing. Don't use any product or accessories in your hair during this time. If you are a violent sleeper like I am (tossing and turning), it's OK to flat iron your hair straight again as needed. After 3 days, wash with a shampoo specifically designed for keratin treated hair. It MUST be sulfate and salt-free (more below).Maintenance: There isn't much to maintaining the treatment other than to use quality products. I use Keratin Complex Color Care Shampoo and Conditioner that I only buy from Ulta (3rd party sellers on Amazon are known to be knockoffs). Yes, it's expensive at $48 for a 32oz bottle...each. It hurts a little when I buy them. Actually, it hurts A LOT but it's worth it. I've been using them since my last treatment and without a doubt is the reason why it lasted so long. BUT, I picked up a set of Loreal Ever Pure Moisture Shampoo/Conditioner for camping and it's every bit as good and much more affordable ($17/23oz bottle). I don't get any kind of kick back from mentioning these two brands, just personal experience.Also, be kind to your treated hair. Keep it natural as much as possible, use sulfate/salt-free products (even dry shampoos, hair spray, etc.). Nothing will strip your hair faster than salt. Limit use of heat stylers. Other than doing this treatment I haven't used my flat irons in a year. When I have needed to blow dry my hair it takes much less time and I can use the low heat setting.Hopefully this review helps if you are looking for something to try at home.

This product is worth every penny. My life has seriously changed after using this in my hair. I’m tempted to buy several more orders just in case it gets discontinued or sells out or Amazon crashes, because I don’t think I could go without it. I’ve hated my hair for YEARS. I’ve tried so many different products. My hair is part curly, wavy, and straight. It is also very thick in texture and volume. I also live in a very humid climate, so there are so many things going against me. Honestly, my hair would prevent me from doing normal things (exercise, swimming, etc) because I hated the idea of needing to spend more time drying and styling it. Now, I do all of those things and don’t spent more than a minute on my hair after.I wanted to go all out and make sure I didn’t run out of product when I tried this (see other reviews that ran out and mixed with water). So I bought two of the 4oz products. Anytime I go to the salon, they need “extra product” because of my hair thickness. With this product I only needed the 4oz and it was plenty!! So I’m saving the extra one for later.Now it does give off strong smells when you’re heating it with the flat iron, so a well ventilated area is a must. I showered with the step 1 shampoo. Then I air dried my hair. I applied the second step on my back patio with a fan pointed at me to keep fumes away - this was a GAME CHANGER and it helped dry my hair quicker too. I had a show on the TV since I read it could be a long process. Honestly it took me about 3 hours from the shower to being completely done, but I wasn’t rushing through it and casually watched TV and paused to eat lunch and it seemed to go by quick. I didn’t wash my hair for 24 hours after despite it saying you can wash right away.Now my hair is so soft!! I have a little bit of a wave, but it is so pretty and I don’t feel that I need to style it at all out of the shower or pool. 10/10 recommend this. It will change your life.
