Le Prö Organic Single Pass Progressive Hair Straightening Treatment

Formaldehyde-Free, Organic Hair Treatment for Smooth, Healthy, and Frizz-Free Hair

The Le Prö Organic Single Pass is not just another straightening system — it’s a professional hair straightening treatment that combines beauty, health, and practicality. With a 100% formaldehyde-free formula enriched with organic and natural ingredients, it delivers salon-quality results while respecting the health of your hair and scalp.

Why choose Organic Single Pass Progressive Straightening?

• Powerful natural actives — Okra Extract, Aloe Vera, Hydrolyzed Wheat Protein, Lactic Acid, and Castor Oil work together to provide deep hydration, hair repair, softness, alignment, and intense shine.

• Visible results from the first application:

  • Complete restructuring of the hair fiber

  • Long-lasting hair smoothing from roots to ends

  • Intense shine and sealed cuticles

  • Significant frizz control

  • Deep hydration with mass and nutrient replenishment

Safe, Comfortable, and Professional

Unlike traditional keratin or chemical straightening, this organic hair treatment is free from strong odors and doesn’t cause eye irritation. It ensures maximum comfort for both professionals and clients during application.

How to Apply – Simple & Effective

1. Wash with a mild neutral shampoo

2. Apply the organic treatment mask in thin sections (avoiding the scalp)

3. Processing time: 50–60 minutes (depending on hair type and porosity)

4. Rinse with cold water and dry completely

5. Flat iron at 230 °C (around 15 passes per section)

✔ Long-lasting results — Effects last between 90 to 120 days, with touch-ups only at the roots as the hair grows.

✔ Great cost-benefit — A 110 ml bottle yields 10–12 complete applications on short hair, making it an excellent investment for professional salons.

Organic, Safe & Effective Progressive Straightening

Le Prö proves that progressive straightening treatments don’t need formaldehyde to be effective. With a low pH (around 2.0), this formula promotes deep penetration of actives, delivering consistent and natural-looking results from the very first use. Suitable for all hair types, including curly and frizzy hair.
