Keratin Research Natural Argan Oil Infused Sulfate Free Shampoo and Conditioner 2 bottles Value Set for Keratin Treatments, Maintainance After Care, post treatment shampoo Conditioner (300ml 2 pack)

It is the only shampoo and conditioner I use for my hair. Very good product. Leaves my hair smooth the and shiny. I noticed my hair looks healthier and stronger.

Great for my 3c-4a hair

Was excited to try this after reading all of the reviews. The top half of my hair is not real curly but not straight, underneath it's super curly. My daughter has very thick hair and nice curls, but the top was frizzy. Once we were done with my daughter, the frizz on top was gone!! Her hair was much more relaxed with nice beachy curls. My hair takes much less time to dry and it is so smooth and fully of shine. We were both very happy with the results we each received from using this product. There was a slight odor like others mentioned but nothing terribly offensive.

I bought this shampoo after I had a keratin treatment and it works great. It's very gentle and my hair feels clean and looks shiny afterwards! I would recommend this product.

Be careful picking out a keratin shampoo and conditioner as a lot of them say safe for keratin treated hair but contain sulfates which will strip your hair of keratin. Luckily this one does not. I used a keratin shampoo/conditioner combo in a blue bottle from Amazon which contained sulfates and my hair was staticy and felt like straw. My hair was able to bounce back after using this one... Thank God, as a keratin treatment using runs for around $300 and isnt cheap. This one also made my hair easier to comb through and retain moisture. A bit pricey, but worth the cost

I absolutely love the keritan shampoo and conditioner because they are sulfate-free and are so moisturizing for your hair! My hair feels amazing after washing and conditioning. I have no doubt that keritan research products are just as good as professional salon products. My hair has remained healthy and straight and easy to manage. I just blow dry my hair and its soft and straight; then I run the straightener over it a few times and I'm done! I'm very happy with these products.

This brand is the best I found for my hair because it changes my coarse somewhat frizzy hair, which is partially dyed to cover grays, into super shiny smooth and straight near angel soft.. I can still style and curl as I like or wear straight. Love these products and used them for over a year. Never disappointed with my results. A flier in the package showed the company has additional haircare products. I will be trying them too. After spending so much more for products claiming to give similar results, I've found my perfect fit.

Three stars because I love this shampoo and conditioner. It's the only thing I've found to give my very fine hair a bit of texture and body. If it wasn't for recent orders, it would be five stars! I use a lot more shampoo than conditioner for some reason, so I sometimes buy the larger bottle of shampoo. I have found that after the bottle is open and in use for about 6 months, it starts to smell very different than the beginning product. It also ends up with a more watery consistency, but is otherwise still functional. I do not like the smell of the 'expired' product so I ended up throwing the last bottle away with about 1/4 still in it. I decided to give it another try after awhile and am very disappointed. The bottle arrived with an expiration date in 2028 and claims to be bottled in January of 2025, but upon opening it and first use, I realized it smelled bad and was watery consistency - as if it had been open for months. I requested an exchange, and the new bottle arrived leaking and with the same issues. Returning. Will not be buying this size again. I went ahead and ordered the smaller bottles again, hopefully when they arrive they will be in good shape! Feels like the quality has slipped over the last year, hopefully not a trend and just an anomaly!

My hairs tend to fall a lot and is on the dryer side. This product didn't did anything to help my on that .

I've been using for almost a year and I LOVE IT. My hair is not falling anymore, it’s shinny and looks healthy… amazing product

Is an amazing product, it has helped my hair significantly. Will keep buying this product.

Fabulous shampoo for keratin and colour treated hair. Better than salon products at double the price.
