Post-Smoothing Care: The Complete Guide

Smooth and shiny hair

You just got a Brazilian Blowout, a vegan tannin smoothing or a Hair B.Tox? Congratulations! Now discover how to extend these beautiful results for months with our complete care guide.

The First 48 Hours: Crucial

The first two days after your treatment are crucial for the result's longevity. Here are the golden rules to follow:

Don't Wash Your Hair

Wait at least 48 hours (72 hours for optimal results) before the first shampoo. This time allows the treatment to set properly in the hair fiber.

Avoid Humidity

No pool, no bath, no sauna. Humidity could compromise the treatment's setting process. Protect your hair in the shower with a shower cap.

Keep Hair Down

Don't make ponytails, buns or braids. Any mark on the hair could become permanent during this setting period.

The Right Shampoo: Your Best Ally

Choosing the right shampoo is essential to preserve your smoothing:

  • Sulfate-free: aggressive sulfates strip the treatment quickly
  • Salt-free (sodium chloride): salt breaks keratin bonds
  • Neutral or acidic pH: to close cuticles and maintain shine
  • Gentle formula: prefer "post-smoothing" or "treated hair" shampoos

The Ideal Washing Frequency

The less you wash your hair, the longer your treatment lasts. Ideally, limit to 2-3 washes per week. Between shampoos, use a quality dry shampoo to absorb excess sebum.

Washing Technique

  1. Wet your hair with lukewarm water (never hot)
  2. Apply shampoo gently massaging the scalp
  3. Rinse thoroughly with lukewarm water
  4. Finish with a cold water rinse to seal the cuticles

Hydration and Nutrition: Essential Gestures

A smoothing treatment can slightly dry the hair. Compensate with a suitable hydration routine:

Weekly Mask

Once a week, apply a nourishing leave-in mask or a rich mask that you'll leave on for 15-20 minutes. Prefer formulas based on natural vegetable oils.

Protective Oils

A few drops of argan or camellia oil on the lengths (avoid roots) provide shine and protection. Apply on damp hair before drying.

Heat and Styling: Precautions

Drying

Dry your hair on medium temperature directing the air from root to tip. Air drying is even better if you have time.

Straightening and Curling

If you use a flat iron or curling iron, never exceed 180°C and always apply a heat protectant spray before.

Extending Results According to Your Treatment

After a Brazilian Blowout

Duration: 3 to 6 months with good maintenance. Renew the treatment as soon as you see the first waves reappearing. Discover all the benefits of Brazilian Blowout.

After Tannin Smoothing

Duration: 2 to 4 months. This 100% natural treatment may need more frequent touch-ups, but it fully respects your hair's nature. See our vegan tannin smoothing page.

After Hair B.Tox

Duration: 4 to 8 weeks. Hair B.Tox being primarily a treatment, renew it regularly to maintain hydration and shine. Learn more about Hair B.Tox.

Mistakes to Absolutely Avoid

  • Swimming in a chlorinated pool without a swim cap
  • Using a regular supermarket shampoo
  • Tying your hair tightly every day
  • Neglecting sun protection (UV rays degrade the treatment)
  • Getting a color within 2 weeks after smoothing
