Liquid Keratin Filling Leave-in Conditioner 6.7 fl. oz. 200mL

I first tried this product several months ago when I received a free bottle with my shampoo purchase from Ulta. Now I use it on my hair every time after I shampoo -- it makes my hair feel stronger, silkier, healthy, and keeps the frizz away. It is not sticky or greasy at all, like some of the oil based leave-in products on the market. Also, I get keratin smoothing treatments every 3-4 months, and this product totally complements the effects of those treatments. I hope they never stop making this.!!!

I use sun-in to lighten my hair & never realized that it's peroxide and it was destroying my hair. My new (and awesome) hairstylist told me if I was going to use SunIn I needed to use a leave-in conditioner with keratin (or some other protein-based conditioner). I was having a really hard time finding what I wanted on the shelves in stores so I looked on Amazon. I actually purchased 3 different products; this, Chi Keratin, and Chi Keratin Mist. I'm not sure which has the most Keratin but I like all three. I wet and condition my hair daily but do not shampoo every day. Before I apply the conditioner I towel-dry my hair really well. Then I blow-dry slighly so that my hair isn't too wet so that the conditioner isn't diluted. I have very fine hair but none of these products make my hair feel heavy or dirty.The Chi mist is easiest to apply because it's a fine mist. Chi Keratin and LiquidKeratin are a bit thicker so I use my hand as a shield to catch the overspray and rub the excess into my roots. It makes my hair feel really silky and smooth. Currently my hair is still really damanged and I have a lot of broken ends that make my hair look frizzy. This helps tame the damage and I'm hoping that with regular use my hair will be in better shape.

I don't know why this Liquid Keratin works so well.. but it does! I have Big, thick curly, frizzy hair- and that's after a keratin treatment...This stuff really adds a kick to the treatment, making my hair shiny and lay down so nicely. Btw- I like the smell!

I've used about a bazillion hair care products in my lifetime. Most don't live up to their hype. Some work well for certain people while others not so much. I was looking for a product that would help my professionally keratin treated hair keeps it's silkiness longer. I think I must have gone through 5 or 6 different products before I found this one. I was about to give up and just get another $400.00 treatment. Then, I found it! Yes! Something that does what it says it does! YAY! It isn't sticky, doesn't build up, and doesn't weigh down your hair. It's a spray, but slightly thick, so I spray it in my hands. rub them together, then dap it on my hair. It doesn't take much. I found the best results come from using just a little while your hair is towel dried, before blow drying. Then I use just a little bit more after my hair is dried, but still warm from the blow dryer. I think it will last quite a while and I'll definitely re-order when it's empty. Okay, as for the smell - it's almost non existent. It won't compete with whatever scent you're wearing.

I have no idea what is in this junk but it does not condition. I sprayed in into my hair, which had a salon Keratin treatment a few months ago. Normally after washing, I can comb through my hair, but after I sprayed this stuff on it was stiff and felt like straw, even when it was wet. I tried blow drying it a little and it just got worse. My hair was so trashed!! I had to use a ton of argan oil on it to get it back from the straw state this crap left it in!! It is not like any leave in conditioner or keratin treatment i have ever used. It was like spraying old fashioned hair spray onto wet hair. Learned my lesson, sticking to salon recommended products to protect my color and Keratin treatments!! Stay away!!!

The keratin conditioner is very good and makes your hair feel soft and easy to manage.However the shape of bottle is impossible for me to handle, I spray the liquid in my hand and apply it that way.DeShane

I have fine hair, but I have a lot of it, so it looks thick when I can find the right products to use on it. Most products weigh it down. I found this about 6 months ago and my hair has never looked better. I spray it on the back and ends (not the root or crown area) and it makes my hair silky smooth and full of body. In the last six months several people have told me how healthy my hair looks. I have also gotten compliments on my hair color and my cut - but I think it has to do with how well it lays and manageable it is from using this product. I highly recommend this. I don't use the other products in the line however because I use a thickening shampoo and condition. It is very reasonable and last a long time.

I have used Liquid Keratin for about 1 year now in combination with other supposed remedies in an effort to try to combat female pattern hair loss. I have always loved the smell of this product. However, this time the smell has changed into something that to me smells like animal urine or close. In order to tolerate the smell, I need to mix Victoria Secret's perfume with the leave-in conditioner, so I am not sure how this is going to affect my female pattern hair loss, but will probably be detrimental.
