Liquid Keratin 30 Day Straight Smooth Strong & Long Treatment Starter Kit is a long-lasting, patented, at-home keratin treatment kit that makes frizzy, coarse or curly hair straight, shiny and extremely manageable.

The process is transformative. Reviewers rave that their hair is completely changed – absolutely straight and frizz-free.

The key ingredient in this treatment is keratin, a protein found naturally in your hair. This treatment doesn’t simply cover-up frizz or weigh down curls, it actually repairs hair – infusing keratin into imperfections in the shaft, which causes hair to calm, lay straight, shine and feel silky rather than rough.

Results can last for up to 6 weeks.

Kit Includes:

* 4 oz. Liquid Keratin 30 Day Straight Smooth & Long Treatment
* 1.7 oz. Liquid Keratin De-Frizz Shampoo
* 1.7 oz. Liquid Keratin De-Frizz Conditioner
* 1.7 oz. Liquid Keratin Leave in Conditioner

NOTE: Following each step closely is important for achieving optimal results.

1. Assemble the following items for applying the Liquid Keratin 30 Day Straight Smooth Strong & Long Treatment. (Not all tools are included in the set.)

  • Directions (provided)
  • Liquid Keratin De-Frizz Shampoo (provided)
  • Towel for drying your hair
  • Liquid Keratin 30 Day Straight Smooth Strong & Long Treatment (provided)
  • Fine tooth comb
  • Round or paddle brush
  • Hair dryer
  • Flat iron (that reaches at least 450 degrees Fahrenheit)

2. Prepare your hair for the treatment.

  • Wash your hair very well using the Liquid Keratin De-Frizz Shampoo
  • Rinse thoroughly
  • Do not use conditioner
  • Towel-dry hair

3. Apply the Liquid Keratin 30 Day Straight Smooth Strong & Long Treatment in three easy steps.

    Step 1: Saturate.

  • Spray on the Liquid Keratin 30 Day Straight Smooth Strong & Long Treatment.
  • Separate your hair into small, manageable sections.
  • Shake the treatment bottle well and spray treatment on each section, completely saturating hair.
  • Pull bangs and hair around your face back to spray away from face. Comb treatment through hair, from the roots to the ends.

    Step 2: Penetrate.

  • Allow the Liquid Keratin Treatment to penetrate your hair for 30 minutes.

    Step 3: Activate.

  • Blow-dry your hair straight using a round or paddle brush. Make sure to completely dry your hair.
  • Then, flat iron very (very) small sections with your flat iron turned up to 450 degrees Fahrenheit. This seals the keratin treatment into hair shafts. There is thermal protection in the treatment to protect your hair from heat damage, but it’s still very important to use caution. Always keep the flat iron moving, proceed slowly and avoid ironing over the same section too many times.

4. Allow Liquid Keratin Treatment to sit on your hair for 48 hours.

  • It’s very important to keep your hair completely dry and straight for 48 hours.
  • Any kinks or curls (from humidity, rain or sweat) should be flat ironed out. Do not use pins or clips in your hair during this time.

5. Neutralize.

  • After 48 hours, wash your hair with the Liquid Keratin De-Frizz Shampoo.
  • Condition with Liquid Keratin De-Frizz Conditioner. Allow the conditioner to sit for 1-2 minutes and then rinse with lukewarm water.
  • NOTE: It’s very important to use keratin-conscious aftercare products. They are specially formulated to work with the treatment – enhancing the effects and extending the life. Non-keratin aftercare products (shampoos, conditioners or styling) may cause your keratin treatment to fade more quickly.

6. Apply Liquid Keratin Filling Leave-In Conditioner

  • Towel dry your hair and apply the Liquid Keratin Leave-In Conditioner. This product coats your hair and fills in the hair follicles to condition and moisturize.

7. Style your new, straight, shiny hair.

8. Smile because your hair will be polished and manageable for weeks.

  • Liquid Keratin Works Fine - Just Not As Good 4 Star Rating
    OK folks, the product does work just not nearly as well as the ad promises. Basically, it cuts down frizz and makes hair less curly but long ways from straight. I still think it is a good product for many folks out there, especially those with wavy to moderately curly hair, assuming your goal is to have more manageable hair. I also like the way my hair feels. It seems gentler than the other products on the market. But then, for three times the price, you would expect that.

  • Fab Hair 5 Star Rating
    Liquid Keratin is safer than salon products. It does not smell bad and very easy to use. If you don't want harsh chemicals this is the product for you. Yes it's a pill to have the product on for for two days. But the reward is Fab hair. I won't use any thing else on my hair.

  • Best For Your Money 5 Star Rating
    Considering I was paying this much for relaxers that damage my hair, I say this product is a great use of my hard earned money. It made my hair much more easier to straighten and it's straighter. I'm currently transitioning to my natural hair, and I can see these products as part of this process. You just have to follow the process EXACTLY or you WILL screw it up. Pros: 1. Easier and healthier than a relaxer. 2. Made my hair easier to straighten than other products 3. Shampoo is sulfate free. And yet you still know where you applied it. Cons: 1. Process will be confusing for some 2. Smells a little funky PS you don't have to keep re-buying this kit. Only the parts you run out of, and you only need to do the treatment as needed. DO NOT use products with sulfates in them, it will frizz your hair out. You shouldn't be using them anyways.

  • Silky Smooth 4 Star Rating
    A few months ago I did a Marcia Taxiera(sp?) Brazilian straightening at a salon for $400. That lasted a few months. And I loved the results. I was looking for something similar but cheaper that I could do at home. The Liquid Keratin is a lighter weight product than the salon treatment. And I'm assuming it won't last as long. BUT the upside is, for $69 I have enough product to use again in a month. I love the silky smooth feeling. And I feel like I can probably use the product as needed for just spot treatments that aren't possible at home with the salon treatment. (duh) I would say all in all it was what I expected. And I'm pleased with the results. But I've done all the treatments: regular chemical relaxer, Japanese straightening, salon Keratin, and I know what's possible with my hair. I'm a realistic girl and I know this is the best I'm going to get for the money right now. My hair feels amazing... great condition, shiny and silky smooth. BUT be realistic, this is not a straightener. My hair is still curly when I wash it. However after using the flat iron my poodle head is gone and doesn't frizz as badly in the humidity. Yeah!

  • Not Bad . . . 3 Star Rating
    but not great. I have grey hair that has been relaxed (albeit with a ton of grow out right now!), and this product yellowed the grey that had been relaxed. It was fine on the un-relaxed hair. As my calling card is my great silver hair, I won't be using it again. I think it did make my hair (coarse and frizzy) easier to manage, though not by much, but my hair was definitely softer.

  • Smells Bad, Not Effective 1 Star Rating
    I followed the instructions exactly and I did not see a marked difference in my hair, other than a lingering bad smell. You have to wait 48 hours after the initial application to wash your hair, so I looked like I had greasy hair for 2 days...ugh. This was definitely not worth the trouble or the money.

  • Nope Don't Waste Your $$$ 1 Star Rating

    Does little to nothing to straighten hair. After doing the treatment I still had to do my entire straightening routine. Barely any diffence to my hair. Don't waste your money.

  • I've Been Waiting For A Product This Good My Entire Life!! 5 Star Rating
    Liquid Keratin is worth every penny I paid. Not only did it do everything it promised, the results went beyond what I was hoping for. My hair is straight without any waves and is shiny and easier to manage. No frizz at all. I was just resigned to dealing with my thick and wavy hair. Now with the results of Liquid Keratin, my self confidence has increased by defying my DNA. I will continue to use this product and will recommend it to anyone who notices the difference in my hair. Thanks a million!! Better late than never!!
