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.

    My hair seemed nice and smooth for the 48 hours after first application. However, after the first wash, I was back to frizz city. Not worth the price... A regular styling product would have probably worked as well...

    I had long healthy hair before I used this product. I purchased this thinking it would be a good treatment for my hair... wrong! There is a very strong chemical smell when using this product. How can something that smells so bad be safe for your hair?
    When I first applied the treatment to my hair it did feel silky. I washed my hair two days later and OMG... DAMAGE CITY! My hair looks and feels thinner and it turned a weird color. My ends were damaged beyond repair. I had to get it cut to my shoulders (i'm still in tears). I called the company that makes this and they say their product cant cause damage. Really? Do not use this in your hair!

  • Such A Waste!!!! 1 Star Rating
    This product was a waste of time and money. It smells like crap, and as soon as I washed my hair for the first time it was like I hadn't done anything.

    I love the idea of an at-home treatment but this one failed on so many levels. I will stick to the salon until there is an at-home treatment that actually does something.

    Does anyone have any recommendations???

  • This Is Not What Its Cracked Up To Be! 3 Star Rating
    I believe if you are mixed or of African decent it will not work as well. I feel like my hair as a coating on it all the time. It does not protect my hair from humidity, when it is hot and humid the ends of my hair get frizzy now. Yes, my hair does feel softer, but my hair wont hold curls for too long, it falls flat all the time, my heair feels heavy and has no bounce my only option is to leave it straight all the time. This product gets a C- from me. I followed the instructions to a T, and still I didd not recieve the results I thought it would. I just applied the product 3 weeks ago. Maybe I should have paid the $250 at the salon for the real thing. This is not what it is cracked up to be, seriously.

  • It Works 4 Star Rating
    I purchased this product because I am transitioning from relaxed to natural hair. I was skeptical after reading the other reviews, but decided to take a chance. Heck, I spend that much on relaxers! I followed the directions except that I combed the product through my hair with each section that I saturated, and once my entire head was completed, I combed it through again. Instead of using a round or paddle brush, I used the comb attachment on my blow dryer. I have to say that I am impressed, and will continue to use the product as I make my transition.

    This stuff is a waste. It did nothing for my hair. Absolutely nothing. I followed the instructions to a "T" but it just doesn't do anything. I used this in hopes of being able to let my hair air dry every once and a while, but my hair dried just as poofy and curly as normal. I didn't experience any extra damage with this stuff, but have heard of people who's hair got fried. Others who's color was ruined (if you have highlights, watch out). I also don't like that they lie and call this stuff formeldyhyde and chemical free. Its not. It has a form of formeldihyde called Biformyl in it. I wrote the company on this and they just responded with vague, form letters. No specifics, no explanation. Not cool.

  • Waste Of Your Money And Time 1 Star Rating
    I have curly hair - not the super tight corkscrew curls but loose, wavy curls that frizz if there's too much humidity in the air. After reading all these reviews, I figure I'd give Liquid Keratin a try. What a HUGE waste of my time and money. I followed the instructions to the T! Did everything it said to do, every single tedious, time consuming step and used every last drop of the solution. Even bought a special flat iron that goes up to 450 degrees and flat ironed my hair. The flat iron cost me a fortune. BUT, I wanted followed the instructions. It looked great the day I used it and flat ironed my hair. That is, it looked good until I washed my hair using the shampoo, conditioner and the leave-in conditioner that it comes with. FRIZZ CITY!!!! Not only was my hair AS CURLY as it was before, it's now a little crispy at the ends. Hmm... probably from using a flat iron set at 450 degrees. Did I tell you how long this process took? FOREVER! Sure, you leave the solution on your hair for 30 minutes but they don't tell you that it takes a VERY long time to dry your hair and then to flat iron it, tiny piece by tiny piece. I wish I hadn't wasted my time on this product. Because now I have to wait until it is washed out of my hair so I can go to the salon and pay to get the real Brazilian Straightening done. 4 to 6 weeks of miserable frizzy hair until I can get it straightened. Girls, if you do the math and spend this kind of money every 4 to 6 weeks to straighten your hair at home, you would have spent the $250 that it costs to have a professional do the straightening for you. Run, don't walk away from this product. Save your money! Save your time! Save your sanity!

  • It Works But... 4 Star Rating
    Okay, this does what it says it will do. All the fuzzy ends and fly aways are gone and I had awful hair, dry, frizzy, unmanageable in the humidity. So I give it an A+ for that! However, the shampoo, conditioner and leave in conditioner STINK! It's a horrible smell like dirty socks--yuck. I went elsewhere to look for a keratin treatment friendly shampoo and conditioner that have a better smell. I rated this good because I am happy with the look of my hair but the smell is too overwhelming to call it the best. I hope this company can impove the smell, anything would be better!!

  • Not Worth The Money 2 Star Rating
    I had high hopes for this product from the reviews. I understand that keratin in the salon is very pricey. But this product is definitely not worth the cost even though it is cheaper than salon keratin. First of all....It made my hair smell like burnt salted nuts. I know that sounds weird...but I asked my hubby, and he agreed. I have washed my hair 3 times since the treatment, and it still smells! It did straighten my hair, but it is dull looking. Who wants that? Also...my $100 highlights are now orangey. Soooo....obviously, I would not recommend this product.
