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.

  • A Curly Hair Miracle 5 Star Rating
    I have tried Chi straightening, spent hundreds on flat irons and products, blowouts and no-frizz serums. My corse, curly and frizzy hair ruled my life.I read about this product after hearing about it in a People magazine. I thought it was just another hair gimmick, but decided to give it a try since it was not permanent. WOW, my hair has never been so soft and smooth and easy to manage. I can air dry it, straighten it in 10 minutes or wear it curly. I actually have gone a whole week without using a single product on my hair. I am hooked for life.

  • So Far No Frizz With Liquid Keratin 4 Star Rating
    I did the treatment about 6 weeks ago and have used only the Liquid Keratin shampoos and conditioners since (as they strongly recommend.) My hair is about the same to blow dry time-wise, but it looks better - lots of body and with that naturally smooth look. The product is fabulous at protecting against heat damage. I now use a professional style flat iron as well sometimes, and my hair is holding up very well. My hair will wave and maybe curl in humidity, but it doesnt frizz. And the flat iron makes it good as new in just a few minutes.
