Liquid Keratin - Home Keratin Treatment
Liquid Keratin - Product Review
Liquid Keratin is a new keratin treatment for frizzy, unmanageable hair that can be used at home. You spray it in and wait 30 minutes for the keratin protein to penetrate the hair.
Liquid Keratin doesn’t have the strong straightening properties of Brazilian Keratin Treatment, formaldehyde, or similar chemicals. It will not make hair 100% straight but it’s an effective anti-frizz product for natural curly, hard-to-control hair. It also adds strength and thickness to hair, making it appear healthier.
The product contains hydrolyzed keratin extracted from New Zealand wool. The molecular weight of hydrolyzed keratin is much smaller than other types of keratin proteins. So it will not only coat the surface of the hair for protection and strength, but will penetrate into the hair shaft and act as a deep conditioner.
Theoretically the product can also be used as a repair therapy for damaged hair that needs reconstruction of the hair cuticle.
Lasting Power
One of the downsides of Liquid Keratin is that it won't last as long as a salon treatment. The effects of Liquid Keratin last up to 6 weeks compared to several months with salon treatments, so you will need to reapply it more often. The starter kit (only available in US) costs around $70 USD and is enough for 30 days of treatment for medium-length hair.
Another problem is that it can't be used with regular shampoos and conditioners that contain sodium chloride. The company recommend that it has to be used with its own shampoo and conditioner to ensure lasting results.
Usage Questions
Since this product is new, there are bound to be lots of questions like:
“Can it be used on color treated or highlighted hair?”
“Can it be applied on already relaxed hair?”
“Can it be used on African American hair?”
According to the manufacturer, the answer is yes to all the above.
But for those with blonde, highlighted, or bleached hair, I suggest you do a hair strand test before using Liquid Keratin. That’s because the hydrolyzed keratin has a yellow-brown color and could cause noticeable discoloration of blond hair color.
Liquid Keratin Ingredients

Is it 100% formaldehyde Free?
Yes and No. The product is 100% formaldehyde free but it contains Biformyl, which is formaldehyde derivative with synonym name Glyoxal or Oxalaldehyde (C2H2O2).
I went to Ulta, a discount cosmetic store like Sephora, and found a kit to do at home myself called liquid keratin in a brown box for my 4yr old daughter who has hair much like the other mom's ten year old and I must say it does make a difference in her short natural "nappy" hair. 
Great product !!!
Since your product is not formaldehyde free. It is very important that you always show the percentage used and if it is or not authorized by
It's actually not the keratin - which is several ingredients down on this list and is a common conditioner ingredient - that is doing the smoothing out with this product - it is the three or four silicone (they end in "cone") ingredients that appear first on the list of ingredients. 
I love this product. The directions were so easy to follow. Everyone noticed and asked wow what did you do to your hair it looks so healthy. This line now sells in Canada.
Well I have just paid $250.00 at the hair dressers to-day. My hair is very curly, wispy, and fine i am due back to Aus for my holiday, so i was unsure if I sent for the Home Keratin Treatment it would not get to me in time with the Xmas Post.
