What to Expect During a Cezanne Classic Keratin Smoothing Treatment

Getting a Cezanne Classic Keratin Treatment in the salon is a quick and comfortable experience. Here’s what you can expect:

Step 1: The Prep

The stylist will gently cleanse hair twice using Cezanne Clarifying Shampoo to remove buildup and prepare the hair for treatment.

Step 2: Application

The Cezanne Classic Treatment is applied in sections, starting at the nape and working up toward the crown. The treatment is evenly distributed using an applicator brush and fine-tooth comb to ensure full coverage while avoiding the scalp.

Step 3: Processing Time

Hair is left to process, which may be longer for coarse or resistant hair).

Step 4: Blow-Drying & Heat Activation

After processing and thoroughly rinsing, the stylist will blow-dry hair 100% dry before sealing in the treatment with a flat iron. This meticulous process locks in the smoothing effects, ensuring a long-lasting finish.

Step 5: Ready-to-Wear Results

One of the best parts about Cezanne Classic Keratin Smoothing Treatment is that there’s no downtime. With Cezanne, you can wash, style, and even hit the gym immediately without worrying about ruining the results.

Cezanne Classic vs. Express Treatment

While the Classic Treatment lasts up to 5 months, Cezanne Express is a quicker, more affordable option that lasts up to 10 weeks. Express is ideal for:

Clients who want a faster salon appointment
Those who get frequent refreshes
Taming baby hairs, bangs, or cowlicks
A more budget-friendly smoothing treatment

How to Maintain Your Cezanne Treatment

To extend the life of your Cezanne Classic Keratin Treatment, regular refreshes and home care are essential.

Use a Sulfate-Free Shampoo & Conditioner – Sulfates strip the treatment faster, so switch to Cezanne Perfect Moisture Shampoo & Conditioner , Revive Curl Shampoo & Conditioner to keep hair smooth and hydrated, or Ultimate Blonde Shampoo & Conditioner for blondes looking for a cool finish.
Cut Down on Heat Styling – Hair will be easier to style, but excessive heat can still damage strands. For this reason—and to enhance longevity of your treatment—use a heat protectant, like Cezanne Leave-In Perfector Spray to guard your hair.
Sleep on a Silk Pillowcase – In addition to being great for your skin, silk pillowcases reduce friction as you sleep to prevent frizz, helping to keep hair smoother for longer.
Refresh Regularly – Depending on your hair type and maintenance routine, schedule a refresh every 3–5 months to keep hair consistently sleek and frizz-free.
