But it smells so horrible after the heat styling *by on Reviewed in the United States August 9, 2025* 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. ### ⭐⭐⭐⭐⭐ Very efficient *by on Reviewed in Saudi Arabia May 20, 2025* Excellent product ### ⭐⭐⭐⭐⭐ Le meilleur!! *by on Reviewed in Canada December 20, 2022* Une valeur sûre.
