Keratin Treatments: Pros & Cons
June 04, 2021

A keratin treatment is an advanced chemical procedure that is performed to make hair more manageable, add intense shine, and help reduce frizz. Depending on the product and stylist, the entire procedure can take less than an hour or several hours. Most commonly the process involves washing the hair, then having the treatment brushed onto wet hair for a period of processing. Sometimes the hair may be blow dried first and then the treatment is applied to the dry hair. It is possible that you are considering a keratin treatment, but you are uncertain if the treatment is right for you. So let’s weigh the pros and cons.

Keratin Treatment Pros

Our body naturally produces the protein keratin, such as our nails and hair. The keratin in treatments are potentially derived from wool, feathers, or horns. Certain hair care products contain keratin as well. If you get a keratin treatment done by a professional, you benefit from the following:

Smoother, shinier hair

As the keratin smooths cells that overlap from hair strands, this makes your hair more manageable with much less frizz and a more glossy appearance.


As long as you are not washing your hair more than a few times a week, a classic keratin treatment should last three to five months.

Instantly manageable hair

If you have frizzy or thick hair, these types of treatments will ensure that your hair is more manageable. Drying your hair will also take half the amount of time. One potential positive effect of a keratin treatment is that you may develop stronger, more healthy hair.

Hair growth

With strengthened hair, the keratin treatment fortifies and protects hair so that it doesn’t break off or cause split ends. This can make hair growth seem faster than usual because ends are not breaking off.

Keratin Treatment Cons

While there are many benefits to keratin treatments, there are also a few considerations to be aware of:


Many keratin treatments contain formaldehyde which is dangerous when inhaled. This is the chemical that actually makes the hair look stronger. More permanent straightening options like relaxers (sometimes called Japanese straightening) actually break hair bonds using the ingredients ammonium thioglycolate and sodium hydroxide. This makes for permanent results, but can also cause an awkward growing out phase with non-treated hair growing curly at the roots. 

Hair Color

 It is possible that some keratin treatments can sometimes remove or lighten your hair color, which may require toning after the service to rebalance your hair color.

The Bottom Line

Keratin treatments help make frizzy, thick hair easier to manage, and significantly smoother. We only use formaldehyde free keratin treatments, for your safety and ours. We believe in our Cezanne Keratin Smoothing Treatments because they promise never to use harsh chemicals and have the documentation that proves it.
