Keratin Research Keratin Forte Conditioner, 300ml, Unisex, Moroccan Argan Oil Enhanced Formula for Curly Hair

This is my go-to keratin treatment and I’ve been using it for years with great results. My hair always feels smooth, healthy, and easy to manage after using it. I was a little nervous ordering again because my previous package got lost, but customer service was excellent and I received a full refund. This time, the shipping was super fast — it even arrived several days earlier than expected! I’m very happy with both the product and the service. Highly recommend!

At $65.00, I will get at least 3 treatments out of this one bottle. When I had it done at a salon it was $180. I love it! The smell is overwhelming and it stung my eyes so be sure to be in a very well ventilated area. It took me about 4 hours to complete the entire process but I was taking breaks and doing other things. I'm sure I could have shaved off some time if I had just powered through it. I'll repeat...I LOVE it! It came out great and what I love best is that my hair stays smooth and nice in humidity. I went for an evening run and it was damp but did not take on the frizz ball look that it would have otherwise. I highly recommend this product and will definitely purchase it again.

It did not straighten my hair but it did losen the curls. It also made my hair much softer and shiny. The process is long and tiring. I don't think I'll be doing it myself again. Also the fumes are serious! It gave me watery burning eyes and sore throat even though I wore an N95 mask and had a fan with good ventilation.

I did a lot of condition masks for a couple months before using this treatment, just to make sure my hair would survive a 450 degree flat iron. That being said, I loved the customer service, they sent a follow up after I received the product with more information and video links, and a number to call with questions. I’ve got experience with keratin treatments, and this one was easy and my hair is straight and soft, with less frizz. I left it in 7 days, and washed it last night, it looks great one wash in. Pictures are a blow dry before and the blow dry after, with one side not done yet. No flat iron used. Ventilation is a must, it did hurt my eyes when I blow dried it, not so bad at the 2.5 hour flat iron though. Thanks❤️

Its official, you can buy anything on AMAZON! Okay.. so this product line has been my best purchase in a decade!!! Anyone who has frizzy hair needs to purchase this. I previously spent lots of money on a keratin treatment but money in the pocket after now that I found this keratin treatment and shampoo and conditioner. Its been 3 months and my hair is still straight. This entire package is 100% worth it... I would post before and after but its truly too embarrassing to post the before... total frizz, big and ugly. I went from an hour of drying and straightening and now all I have to do is blow dry with this keratin treatment.

Ok so I was on the fence for a really long time. I read reviews for weeks! 1st of all this does not compare to a salon at all. If you’ve received a high quality kertain then you know when I mean. Process was fine to do. I just did my hair in my room with the window open. The formula did remove frizz, and the dry time is faster the curl is looser. I would say after getting the supplies and accessories I paid 1/3 of the price for 1/3 of the results. I have fine curly maybe a 3a prior to having my hair kertain-ed 3 or 4 times. So given that my hair had some treatment in the bottom half already I was surprised how curly my hair was at the end of it. Basically this product helped me decrease blow drying time and frizz but it did not make my hair into a wash and go easy breezy like the salon kertains did. I still has curls left over after.

I have very thick and course hair that gets frizzy, wavey, and unmanageable as it dries BUT after this treatment (!*following directions!* with my friends assistance), it changed. I love it.... soft, shiny, straight... I stopped putting it in a bun to hide its craziness. I started rocking the long locks with no styling necessary and, when hot, a beautiful ponytail... no straightener, curling iron, or other hair products. This product has changed my hair and somehow brought it from dry to normal. I have continued to use sulfate free shampoo (Neutrogena) and actually stopped using conditioner which was always necessary. Hard to brush wet, but the results are worth it and my hair is doing great 2 months later!!!

second time buying, I'm a male with fine blonde hair and have used this a couple times, finally bought the larger bottle. Always exceeds my expectations, makes hair healthier, shinier, and most importantly: NEVER FRIZZY! I moved from Calgary, Canada, which has low humidity to Orlando Florida, which is extremely humid. That was the real test, and my hair is still perfect all the time! Don't often write reviews but this time I had to... This product needs to see more use!!! Definitely will help a lot of people who have qualities of their hair that they constantly battle. I literally blow dry my hair for 2 minutes as opposed to 10, and leave with it being consistently well styled. WORTH IT!!!
