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

Really liked this product. It made my hair feel super smooth and way less frizzy. It also added a nice shine without making it feel heavy. Pretty easy to use and the results lasted a while. I also like that it’s formaldehyde-free. Overall, solid product—would buy again

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.

⭐️⭐️⭐️⭐️⭐️ 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.

Best product, it really works, my hair is now as straight as a Chinese hair😊

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.

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.

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 love Amazon—it never lets me down. Excellent product.
