It doesn’t do anything. I tried it on 2 separate occasions. It does nothing except leave your hair smelling gross.

It straightened my curly hair without formaldehyde
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.

Great product
I AM SO EXCITED I FOUND THIS PRODUCT! I am from Middle east and my hair has always been curly, frizzy, and on the drier side. My hair is is also damaged from frequent heat styling and a few dye jobs. This keratin treatment made my hair feel a thousand times softer, less frizzy, and a lot straighter. That said, this product is amazing and I am so glad I gave it a shot! I also only used 1/4 of the bottle, and I have very long hair! I tried at least 4 other products before. Applying the product was really easy, Unlike other products it had no smell or smoking. The result was good too. The best part was: I didn't have to wait for 3 days to wash my hair. It worked. my hair is soft and straight. I recommend this product.

Bottle no 2, actual treatment, was only one without protective cap so seller probably opened and added water, it was pretty runny, not like on the video.

Okay, so far I am absolutely ENAMORED with this product!!!! So much less expensive than getting it professionally done. I’ve never done keratin before but I think I did a really good job! PLEASE WEAR GLOVES AND A HIGH LEVEL MASK WHILE USING THIS PRODUCT. Do NOT handle the treatment directly on your skin. Do not use this product after shaving, waxing or exfoliating your facial skin. All I wanted was to not have to worry about my hair for work, the hospital, and clinicals as a healthcare professional and student. As a model, this hopefully makes my life easier and I should still be able to have my hair curled for shoots. But I haven’t finished working with it yet… I did some of the steps out of order by accident. Here is your comprehensive guide of how I did this, and the honest truth about it so far. So I double-shampooed my hair with a clarifying shampoo, and then put the product through all of my wet hair for one hour. After doing this, I left it on for an hour. Then I ended up blowing my hair dry with a round brush (two different types of hair dryers) and then went over it with two different straightening irons. This is where I made a mistake - you are supposed to RINSE this product out after an hour and use a deep conditioner for 5 minutes (see step 5). I mistakenly left it on for about 24 hours. Do not leave it on for that long. The fumes aren’t good for you - you should be wearing a high level K/N95 or elastomeric mask while working with these chemicals. (Google Brad Mondo Keratin - you’ll see). The actual product doesn’t smell bad - it’s actually a cream and it can splatter a little. But it is easy to spread on your hair and cover each strand. One 3.4 oz bottle was more than enough for my hair, even though I have long, dense hair. As you can see in the photo, my hair has no frizz, and it’s so shiny after rinsing the product and re-drying with a blowdryer and then a straightening iron. CONS: Since I accidentally straightened my hair without rinsing the product, there was a lot of residual gunk on my hairbrushes and combs. There was a strong smell that remained in my hair after that. After rinsing out the product, 24 hours later, my hair smells AWFUL. I did not add a deep conditioner, and it is absolutely disgusting to smell it right now, even though it is very smooth. I expect that washing my hair and deep conditioning it tomorrow should get rid of the odor. PROS: The frizz is gone, especially the ones with my baby hair around my face. My hair is shiny and straight. It’s somewhat soft too. When I went to rinse out the product, my hair did not curl up like it usually does, so the product really did break the bonds for my waves. My only goal was to get rid of the frizz for my professional life in healthcare and studying. This product really worked! Also, here is how to use the product and do it yourself the right way. Good luck! The steps from the website are listed below: 1. Wash hair twice with the pH+ Shampoo, leave the shampoo on hair for at least 3 minutes during each application. Avoid massaging your scalp. 2. Section the hair starting at the nape of the neck and begin to apply ½-inches away from the scalp using the application brush to apply “The Best” on each ½-inch sections of hair while massaging into the hair with your fingers. The hair should be saturated with The Best. DO NOT APPLY ON THE SCALP. 4. Leave product in hair for 40-60 minutes. (60 minutes for maximum smoothing result) Cover the hair with a plastic cap. 5. Rinse product out of hair with warm water. For color-treated hair: apply GK Color Protection Moisturizing Shampoo and rinse. Apply Deep Conditioner for 5 minutes, rinse thoroughly. 6. Blow-dry the hair straight on high heat with a round brush using sufficient tension to smooth the hair until 100% dry. 7. Section the hair and flat iron with GK Hair Titanium Flat iron at 400 degrees. If the hair is overprocessed, flat-iron at 375 degrees, lower the temperature further if the hair is very weak and damaged; especially towards the ends of the hair. Pass the flat iron about 2-4 times in each section. 8. Clients are free to wash their hair at any time after the treatment, using GK Hair Shampoos and Conditioners fortified with Juvexin to maintain the results of the treatment.

Questo prodotto deve essere acquistato insieme al kit completo, ovvero acquistare altri 3 prodotti per un costo complessivo pari a circa 210 euro. Ciò andrebbe specificato perché magari alcuni utenti potrebbero usarlo saltando i passaggi fondamentali dati dall’uso dello shampoo pre-trattamento, dello shampoo specifico, del conditioner e della maschera protettiva. Quindi tengo a ribadire che l’uso di questo singolo prodotto è assolutamente sbagliato se non si acquista il kit completo. Una volta acquistato dunque il kit ho seguito bene le istruzioni e ottenuto, in circa 3 ore, capelli lucidi, lisci e leggeri. Spero solo che questo trattamento abbia una durata ragionevole, magari protratta per qualche mese. Ma visto il rapporto qualità prezzo posso ritenermi soddisfatta.
