KERAGEN Formaldehyde-Free Hair Smoothing Treatment Kit | At-Home Health-First Transformation for Salon-Quality, 16 Weeks Frizz-Free Smoothness 16 Oz

⭐️⭐️⭐️⭐️⭐️ Truly the Perfect Product: Restored My Damaged Hair Without Any Harsh Smell I’ve been searching for a gentle, effective smoothing product for a very long time, especially after my hair was badly damaged and even burnt during a professional salon smoothing treatment. Since then, my hair doctor advised me not to use any chemical products for a year. I tried serums, homemade deep‑conditioning masks, and every “gentle” option I could find, but nothing improved my hair quality the way I hoped. Then I came across this product on Amazon and decided to try it after reading the reviews and I’m so glad I did. There is no harsh or strong smell, the formula feels clean, and it worked far better than I expected. My hair became smooth, straight, soft, and healthy‑looking, almost like a salon finish but without any damage. The best part is that I didn’t even use a straightening machine or flat iron. I actual hair is wavy and not straight or smooth at all. I simply followed the instructions, applied the serum at the end, and used only a hair dryer to finish. That was the only heat I used. This product has genuinely transformed my hair and restored my confidence. After everything my hair has been through, finding something this effective and gentle feels like a blessing. Highly recommended for anyone with damaged, frizzy, or previously over‑processed hair.

I’ve used this set three times. The first two times I used the Forte treatment and that’s when I saw the biggest change, because my hair is thick and was very damaged. It helped a lot with frizz, smoothed the texture, and made it much more manageable. That said, it does have a strong smell, so I recommend using it in a well-ventilated area and avoiding inhaling it directly. The third time I used the green one (the milder version) together with the mask for maintenance, and I loved the results too. Since I started using them, I don’t need to flat iron anymore — I just blow-dry and that’s it. The oil is also great because you can use it before and after heat, and it leaves shine, softness, and an amazing scent. Overall, it worked really well for controlling frizz and improving my hair from home.

Omg the way I love this for my 4c hair . It helps with humidity and frizz . Easy to use and no fumes . The clarifying shampoo is soooo good at deep cleansing and the treatment itself made my hair so much softer and manageable

Works great! Not smelly

I am not happy at all with this product. The first application was applied professionally, but it was really hard to hear, even with really clean hair. After the first week of hair washing, the hair went back to its normal stage. Keep in mind that this hair was supplied with a keratin process from another brand, so it was applied on the new growth. It did not work at all, as you can see from the second picture, which was taken a few days after the first hair wash. I will also add a third picture, showing the hair previously treated with keratin and other hair products from a different brand.

Worked perfectly but read instructions on the bottle. The cardboard insert said to leave treatment on way longer than the bottle did. I went by the bottle and it turned out great so far. I’m over 60 and have shoulder issues so I enlisted help from my mil. I also paired it with the after care treatment which I’m glad I did because it has the heat treatment in it. This sure beat the price of a salon.

I tried it today and I’m incredibly happy with the results!! My expectations weren’t for this to straighten my hair, just loosen my 4a curls in the back of my head. The front curls are already looser (3a/3c) from straightening with heat so I wanted to blend them and help with my styling routine of always having to stretch the curls in the back to match the length of the rest of my hair when curly (when straight, it’s all one length). I bought the clarifying shampoo and mask and used as directed but left the pieces out that didn’t need it. I blowdried all of my hair with my regular comb attachment, not a brush, to activate the treatment and straightened (at 390 degrees). I didn’t do a meticulous job straightening since this was my first time using this product and didn’t want heat damage. I basically just went over my hair 2-3 times, really quickly, focusing mainly just on the hair I wanted stretched. I didn’t straighten as I would if I was actually styling my hair. I immediately washed afterwards and styled as usual. The hair in the back now matches the front and I gained a full inch to 1.5 inches in the back!! I will say there is slight smell. Smells like carpet that’s been freshly vacuumed when you have a pet. It’s not terribly strong but it’s there. I’m hoping it will wash out with time but for me it’s worth it for the benefit it provided on my hair. I use strong smelling products so that helps. I’ll probably be more meticulous with straightening next time I use this to see how it really works but thought it best to err on the side of caution for the first use. The frizz is still there but my hair is incredibly frizzy to begin with and I didn’t use it exactly as directed. Hope this review helps! UPDATE: The smell fades after about 5 washes (I did use a sulfate shampoo a couple times even though you’re not supposed to). Nearly a month later, my curls still look great and styling is so much easier which saves me a lot of time!

I'm happy that there was only a mild smell from this product, but after several uses, my daughter's thick, semi-wavy hair does not look much different than before.
