Keratin Treatment FAQ



Q. Who is the best candidate for keratin smoothing treatment? 

A.Mostly anyone is a good candidate for the keratin smoothing treatment. It is effective on all hair types including : thick, thin, dry, chemically damaged, straight, wavy and curly. This professional service will make the hair healthier as it smoothes the cuticle and eliminates frizz and creates shine.


Q. Can I still receive a keratin smoothing treatment if my hair is highlighted or colored?

 A. Yes, the keratin smoothing treatment works great with highlighted and colored hair. It will enhance the color, eliminate frizz and make the hair look healthier overall.


Q. Will the keratin smoothing treatment reduce my hair's volume? 

A. No, your hair will still have volume after your keratin smoothing treatment. You will still be able to use a curling iron and/or round brush to create body and volume.


Q. Is the keratin smoothing treatment going to make my hair straight? 

A. It depends on what the natural texture of your hair is. For example, if your hair is wavy, the treatment will most likely allow your hair to dry straight. If your hair is curly, then it will eliminate the frizz as it enhances the definition of the natural curl. If your hair is straight, the treatment will eliminate frizz and give your hair a shiny, healthy look. Finally, the treatment will cut down drying time on all hair to 1/3 of the usual time.


Q. How long will the keratin smoothing treatment last? 

A.The results will vary depending on the individual's hair type. and how often they wash their hair. Normal results last for up to 12 weeks but wave can return sooner although it will still be way easier to blow dry.  It is also essential to use the proper support products. This treatment is cumulative so the more treatments you receive, the longer a client can go between treatments.


Q. Can you apply the keratin smoothing treatment directly on top of other relaxers or perms? A. Absolutely. The keratin smoothing treatment works great on chemically treated and damaged hair. The proteins and nutrients help to seal the cuticle and leave the hair looking healthy.


Q. Will I be able to have my color done on the same day as my keratin smoothing treatment? 
A. Yes, ideally you will want to do the color service the same day because the cuticle is already open. If you do have the keratin smoothing treatment and then decide to do color, you will want to wait 2 weeks before having a color service.


Q. What steps can I take to prolong the life of my keratin smoothing treatment? 
A. The most important thing you can do is use the appropriate aftercare product line that your salon or stylist offers. The more often you wash your hair, the less time your treatment will last so you may want to try to wash your hair around 3 times per week if possible.

Q. Will swimming in the ocean or pool compromise my keratin smoothing treatment? 
A. Swimming in the ocean or pool is fine, but the life of your treatment may be compromised if you swim regularly. A leave in serum or conditioner is a great product to apply before swimming to protect the hair from the elements such as chlorine and salt in the water. 

Q. How long do I need to wait to wash my hair after the keratin smoothing treatment? 
A. There is no waiting period using  the Cadiveu type and a three day waiting period for other types. 

Q. Am I still a candidate for the keratin smoothing treatment if I am platinum blonde? 
A.Yes. Your stylist has been trained on how to perform a keratin smoothing treatment and has learned to turn the heat of the flat iron down to 380-400 degrees depending on the condition of your hair.

Q. Can the keratin smoothing treatment be administered on hair extensions? 
A. Yes. Actually this treatment is a great solution to the common issue of hair extensions becoming excessively dry due to the lack of natural oils from the scalp. Ideally, it is easiest to perform the treatment before the extensions are put in the hair. However, if they are in the hair, it is not a problem. 


Q. Is the keratin smoothing treatment permanent or will it grow out? 
A. No the treatment is not permanent nor will it "grow out". The treatment gradually and evenly washes out so there is no "line of demarcation". This treatment does not change the inner structure of the hair, but rather creates a protein layer overlay on the cuticle which protects the hair. As the hair is protected for an extended time, the condition of the hair is improved. 

Q. Can the keratin smoothing treatment be performed on clients who are pregnant or breastfeeding? 
A.Since there have not been any studies or tests on the possible effects, we recommend to air on the side of caution and notperform the service on pregnant clients.  Clients should get their doctor's approval which is up to your discretion.


Safety And Precaution


Patrick Evan Salon is committed to providing a safe environment for both our clients and stylists while performing keratin smoothing treatments and Cadiveu Brazilian blowout services in the salon.

We have done a number of things to ensure safety that sets us apart from other salons.

First we have invested in 5 source capture air filtration systems ( ).  These source capture machines have a long tube that resides over the clients hair and sucks the vapor released from the iron into the machine and pushes it through a ashrae and carbon filter to clean the air and release it pure as it exits the machine.

To ensure that the clients are not exposed to harmful levels of Formaldehyde we have invested in a portable Formaldehyde detection meter that properly measures the level of Formaldehyde present in the air if any.  This machine has an accuracy of detecting Formaldehyde down to the hundredth of a part per million and up to 20.26 parts per million.

OSHA’s guidelines for an acceptable level of formaldehyde present in the air state that formaldehyde present in the workplace is not to exceed .75ppm in a time weighted average of an 8hr workday.

Our tests confirm that we are operating in compliance with OSHA ‘s safety protocols and our readings fall well below the allowable safety limit set fourth by OSHA.
