I Belli Capelli Ravenna Keratin Straightener Kit 2x1L — Professional Long-Lasting Frizz Control

I Belli Capelli Ravenna Professional Keratin is a two-bottle salon-grade straightening system that delivers long-lasting, frizz-controlled hair by combining a deep-cleansing shampoo with a keratin and amino-acid treatment.

This professional kit—also called a hair surgery or Cirugia Capilar system—pairs a clarifying shampoo and a Brazilian-style keratin treatment formulated with amino acids, vitamins A and B, coconut oil and keratin. Designed for use in salons or at-home by experienced users, the 2x1L set realigns strands to reduce frizz, add shine and extend the period between heat styling.

How does this system create a longer-lasting straightening effect?

The Ravenna system works in two steps: it first removes buildup so the treatment bonds directly to the hair fiber, then deposits keratin and nourishing actives to smooth and relax each strand. Repeated flat-ironing during the protocol helps seal the formula into the fiber for durable results.

• Clarifying shampoo prepares hair by removing oils and residues.
• Keratin plus amino acids realign and smooth the hair cuticle.
• Heat sealing with a flat iron locks the treatment for extended straightness.
• Results reduce daily reliance on blow-drying and ironing.

What ingredients make this different from a basic straightener?

Beyond straightening agents, this formula includes proteins, vitamins and natural oils that nourish and strengthen while smoothing. These components help maintain hair health and gloss while controlling frizz more effectively than simple relaxers.

• Hydrolyzed keratin reconstructs and fills the hair fiber.
• Amino acids support strand elasticity and alignment.
• Vitamins A and B help fortify hair and improve shine.
• Coconut oil provides lightweight hydration and reduces breakage.

What is the recommended application process and timing?

Follow the two-step protocol for best results: cleanse with the clarifying shampoo, dry hair to nearly 100% and apply the keratin treatment to lengths (leaving a one-finger gap at the roots). After an activation period, dry fully if needed and flat-iron each section repeatedly to seal the formula into the hair.

• Step 1: Wash with the clarifying shampoo only—no conditioner or mask.
• Step 2: Dry hair at least 80% before applying treatment to lengths.
• Step 3: Leave treatment 30–60 minutes, then blow-dry to 100% if product is heavy.
• Step 4: Flat-iron each strand 15–20 times; wait up to 48 hours before washing.

How long will results last and what maintenance is needed?

Duration varies with hair type and aftercare, but the system is formulated to extend smoothness longer than standard temporary straighteners. Using sulfate-free maintenance products and minimizing aggressive washing preserves the sealed keratin layer.

• Expect reduced frizz and easier styling for several weeks to months depending on hair porosity.
• Sulfate-free shampoos help maintain the treatment longer.
• Avoiding frequent high-heat styling preserves the keratin layer.
• A single 2x1L kit provides multiple applications for medium-to-long hair.

Who is this for: I Belli Capelli Ravenna Professional Keratin is intended for stylists and experienced home users seeking salon-grade straightening with nourishing benefits. It suits anyone wanting smoother, shinier hair and less daily heat styling—particularly those with frizz-prone, chemically treated or textured hair—who can follow the multi-step professional protocol and aftercare recommendations.
