We Don't Want to Breathe Formaldehyde Fumes and Neither Do You!
We care about the impact of the beauty industry on our health and the environment. That's why we only use keratin treatments that don't contain formaldehyde. It might be hard to believe, but most keratin hair treatments include this chemical, which is so toxic that you don't want to breathe its fumes or let it sit on your tender, porous skin.
So, why would anyone do that, anyway? Formaldehyde is a powerful straightening agent, but it works by breaking the bonds that keep your hair strong, and it exposes you to poison at the same time.
We don't think it's worth it. That's why we only use formaldehyde-free brands like Cezanne. These gentler products maintain the integrity of your hair and are great for smoothing and adding shine. They are not hair straighteners, and their results are milder than treatments containing formaldehyde.
Read on for the full scoop!

Here’s an in-depth look at what you can expect from a formaldehyde-free keratin treatment:
1. Smoother, Shinier Hair without Carcinogens
One of the most noticeable benefits of a keratin treatment is smoother, shinier hair. It works by smoothing the hair cuticle (the outer layer of the hair strand). This process eliminates roughness and enhances the light-reflecting properties of your hair, resulting in a glossier and more polished appearance.
Cezanne contains no formaldehyde, carcinogens, or dangerous chemicals. The fumes are safe and will not present eye irritation or breathing difficulties. No mask or special ventilation is required.
2. Reduced Frizz
Frizz control is another benefit of a keratin treatment, particularly beneficial for those of us living in humid climates (shout out to Karl the fog). Keratin helps keep your frizzies to a minimum, even in challenging weather conditions.
3. Manageability
Your hair will be significantly easier to style after a keratin treatment. Whether you prefer sleek straight styles or defined curls, this treatment will make your hair more manageable.
4. Long-Lasting Results
Keratin treatments can last for several weeks, depending on your hair type, the specific treatment used, and your maintenance routine. Many clients report enjoying smoother, shinier hair for up to five months.
5. Healthier Hair
Unlike traditional keratin treatments that contain harsh chemicals, Cezanne's formaldehyde-free products are designed to be gentler on your hair, scalp, and skin. The nourishing ingredients strengthen the hair from within, which is particularly important for those with previously damaged or chemically treated hair.
6. Safe for Sensitive Individuals
For individuals with sensitivities or allergies to harsh chemicals, these treatments offer a safer alternative. The absence of -aldehydes and other irritating substances ensures a more comfortable experience during and after the treatment.
7. Versatile for All Hair Types
Whether you have curly, wavy, or straight hair, keratin treatments can help enhance your natural texture while reducing frizz.
Overall, formaldehyde-free keratin treatments provide a safer alternative that enhances the beauty of your hair without compromising your health.
