Keratin Treatment FAQs

What is a keratin treatment?

It is a smoothing temporary treatment that targets the cuticle or outside layer of the hair by depositing Keratin, a protein that your hair is made up of. The results remove frizz and a percentage of curl from the hair. It is heat activated and will make smoothing or straightening hair much less time consuming or incredibly shiny with body when air dried.


“I struggled with my hair for years before I met Dionica. I have extremely thick, coarse, and frizzy natural hair that always seemed damaged due to constant blow drying and straightening. I tried 3 or 4 Brazilian blowouts before coming to 1313, all of which promised to give me "straight" and "silky" hair. None of these treatments delivered the results they promised and left me disappointed. In the summer of 2012 I decided to give it one more chance, and found Dionica as a "texture specialist" online at 1313. The experience was immediately different, starting with an in-depth consultation to explain the process in detail and manage my expectations. Dionica made me feel 100% comfortable and confident that I knew what I was paying for. A few weeks later I came in for my keratin treatment and I was delighted to find that it had actually worked! The treatment took away 85% of my frizz and curl, just like she said it would. I have been coming back every 6 months for the last 4 years and cannot imagine going back to life without keratin! My hair is not only smooth and shiny, but it is incredibly healthy (and long) because I no longer need to blow dry or straighten it! I urge anyone, especially people who have been disappointed in the past, to give this keratin treatment a try. It completely changed my life! Thank you, Dionica!!” — Jenn Goldman

What is the process?

Hair is shampood three times with a special clarifying shampoo to prepare the hair for maximum absorption. Liquid Keratin is applied and blown dry directly on the hair. Followed by flatironing each strand with 450° iron in sections until smooth and straight. Hair must remain that way until shampood out, at which time hair can be air dried or ironed out for maximum smoothing in half the time.

How long does it take and cost?

It all depends on hair texture, length and desired results. We customize our Keratin service specifically for your hairtype and needs.
We have several and work together to choose the one that will work best with your hair. Average time is 2-3 hours. Prices start at $350.

How long does a keratin treatment last?

Depending on individual home maintenance and which Keratin system chosen, on average between 2 to 5 months.

Is it safe to apply a keratin treatment over colored and processed hair?

Yes, the treatment can be used over, colored,highlighted and previously relaxed hair. However, we advise that any chemical services be done prior to the Keratin treatment. If the Keratin is done first, you will need to wait 2 weeks before chemical services can be done.

I've heard Keratin treatments have formeldehyde?

In most cases, formeldehyde is used as a binding agent to adhere keratin to hair for temporary staying power. Much like in lipsticks and nail polish. We work with the lowest amounts available in our Keratins, keeping you and our stylists health safe.

Is it safe using formeldehyde?

The FDA allows products to contain up to 0.02% formeldehyde. Ours is less. (The Occupational Saety & Health Administration (OSHA) allows products to contain up to 0.1% formaldehyde.)

Will a Keratin treatment damage my hair?

No, Keratin treatments actually help damaged hair by filling in porous areas with keratin and conditioning agents. The hair looks healthier after a keratin. Shiny and manageable.

What is the maintenance?

Sulfate-free and sodium-free shampoos will prevent stripping the Keratin from the hair. However, with each shampoo a little keratin is lost so a keratin based shampoo will continually add keratin to maximize longevity of treatment. Also, avoid excessive shampooing, chlorine, and salt water for maximum benefits.
