  • This Sucks!! 1 Star Rating
    I bought this thinking it would be a miracle product, but its not, it does nothing. Its seriously a gimmick. I'm not the type of person who goes and does reviews online, but with such high hopes for this product, and it basically doing nothing, I was so angry that I had to post a bad review of this product.

  • Liquid Keratin 30 Day Straight Smooth Strong & Long 4 Star Rating
    I have highlighted blonde hair and with an annoying curl in the back of my head. I really liked this product. My hair was easier to manage with the blow dryer and flat iron. Using this product makes me look like I just got my hair done at the salon. Not sure how long it will last, it's only been 2 weeks. But I am using the shampoos/conditioner to extend the life of this product.

  • It Works!!! 5 Star Rating
    I just used this product on my hair and its great!! I have naturally straight hair but with age, I am 45, it has gotten thin and frizzy. I had the salon version done but it left my hair without body. This product took all the frizz out without taking all the body out of my hair and for 45.00 you can't beat that (salon version is 150.00) I have color treated hair and it did not change the color of my hair. Would recomend this product.

  • Turned My Hair Orange! 1 Star Rating
    Hello! I have to say stay far away from this product. My hair was a pale blonde and I thought using this product would keep it smooth and shiny while I was away on vacation. After applying this treatment, my hair turned orange! I contacted the company and they told me that they are aware of this problem(they didn't seem fazed that my hair was orange!)they stated a small percentage of people have this problem. I've read about it happening to a lot of people even woman with brown hair. The hair texture of some people was also damaged. I've had two appointments at the salon(in one month)trying to get my hair to an okay looking point, better but still some orange. I REGRET deeply that i used this product on my hair! BTW The LK company is aware of this issue, their defense is it states to do a strand test before using the product. Yet there is no little statement warning that this product is KNOWN to turn hair orange! Hope this helps! Also the company has no advise on how to reverse the damage.

  • A Great Salon Alternative From A Bkt Veteren 5 Star Rating
    I've been getting BKTs in the salon for about 2 years and love them. I'm biracial and have a considerably thick head of fine, kinky, black hair -- which I also love. I sustained an injury that keeps me from being able to lift my arms for long periods of time to do my hair. The salon BKT gave me healthy, straight, silky, shiny hair with little to no maintenance. It costs me $325 because of the amount of hair I have on my head and lasts 2 - 4 months. I thought I'd try Liquid Keratin to 'stretch' my budget until the next salon treatment, but found that this single bottle gave me the same result as my salon treatment. My hair is silky and smooth (I slightly oil my hair after a BKT of any sort). The treatment promises this texture for 6 weeks, but I suspect it will last longer. I'll let you know. So far, GREAT DEAL ... did i say GREAT? $50 every 6 weeks still trumps $325 at 2, 3, or 4 months ...
