Natural Formula Intense Keratin Shampoo for Frizz-Free Straightened Hair - Retains Straightening Results 3x Longer, Sodium Chloride Free - 13.5 oz

Im using Keratin shampoos for many years. I tried Natural formula a year ago during visit in Israel. I loved the product! It made my hair look so shiny, soft and straight. I recently found that natural formula started to sell their products via Amazon which made me really happy. I’m now using it regularly and very happy from what it does to my hair. It keeps the Keratin longer and makes the hair feel so good. great smell too. Highly recommend product!

perfecto for my hair

I liked this shampoo. The scent is okay, the texture is on the heavy side with less leathering up. Doesn’t give you that cleaned, refreshed soft hair. On the very first wash, my hair looks thicker and healthier yet also weighted down a little. Which I liked a lot since, my hair looked thinner, and a bit frizzed up n dry at the end before. I have straightened long hair up to my hips. Ordered the conditioner, let’s see what happens....

I'm an amazon avid shopper, and I must say, this is my second review in years, I hardly write any. But, I had to write a review of this product. I had an awful experience with a blue shampoo that turned my beautifully balayage hair purple and green. I went back to my hairdresser who got rid of the terrible color but my hair ended super dry and brittle, burned. I thought of cutting my hair, it was ruined. Then a friend told me to get a Brazilian blowout, but I didn't like the idea of spending another 350 bucks on my hair. I went to amazon and searched for a product. I ended up buying the combo: shampoo, conditioner, hair mask, and drops. Needless to say, it saved my burned, coarse hair; now I have soft and shiny hair! A miracle in a bottle!!!

Well...I know it said it was for hair that had been straightened...well...my hair was permed and it was permed too tight and ended up being too curly and too frizzy! I was looking for something to relax it without actually going thru the relaxing process. So I purchased this shampoo, conditioner and mask. I used it for the first time yesterday. I actually used the shampoo and mask. Wow! My hair came out soooooooooo soft! I also used DIVA foam anti frizz mouse before I dried my hair and it was perfect! Soft and not frizzy! I do blow it out but one day I will just let it air dry with curls and see if it relaxes them a bit into the "waves" I wanted from the perm! Good stuff!

I love the smell and I love how my hair feels so far (I have only used it two times). However, my concern is that it not sulfate free and sulfate can strip the natural oils from your hair and scalp and that could make it dry and brittle plus it could make your scalp sensitive and itchy. So I don't think I will keep buying it.

I get Brazilian blowouts, all 3 products, shampoo, conditioner and mask are amazing. Keeps my hair super smooth and shiny. Does not dry my hair like many products that I have been trying out. I don’t plan on trying anymore, this is it.

I was afraid in buying a new brand, but since the price was good, I tried. The product did not disappoint ! You only need a small amount to make it work. My hair looks great and it smells wonderful ! Also, the delivery was super quick (free next day with prime). I recommend !
