I Belli Capelli Ravenna Professional Keratin Straightening System 2x1L — Long-Lasting Frizz Control & Shine

I Belli Capelli Ravenna Professional Keratin is a two-step salon-grade straightening system that uses keratin, amino acids and vitamins to deliver a long-lasting, frizz-reducing straightening effect.

This kit, also described as a professional "hair surgery" system, combines a clarifying shampoo and an intensive keratin treatment to realign hair fibers for smoother, shinier results. Formulated with keratin, amino acids, vitamins A and B, and coconut oil, the system aims to reduce frizz and make hair easier to style while extending the time between heat styling. Intended for salon or at-home professional use, the two 1L bottles give enough product for multiple applications depending on hair length and density.

How does the Ravenna system create a long-lasting straightening effect?

The treatment works in two stages: deep cleansing to remove build-up, followed by a keratin-enriched realignment of the hair shaft. The keratin and amino acids help smooth cuticles while concentrated acts rebuild surface texture so hair lays straighter for an extended period.

• Step 1: Clarifying shampoo removes oils and residues for better product penetration.
• Step 2: Keratin formula bonds to hair fibers to smooth and reduce frizz.
• Heat sealing: blow-drying and flat ironing lock the treatment into the hair structure.
• Results last longer than conventional styling because the fiber alignment is preserved.

What results can I expect immediately after the treatment?

After completing the protocol, hair typically feels smoother, appears shinier, and is noticeably easier to manage. The treatment reduces the need for daily heat styling, creating straighter strands with less visible frizz.

• Softer texture and reduced tangling for easier comb-throughs.
• Visible shine from nourished cuticles.
• Reduced drying and styling time following application.
• More uniform hair shape, improving overall styling predictability.

How is the I Belli Capelli Ravenna kit applied safely and properly?

Follow the multi-step professional protocol: cleanse thoroughly, dry hair to the recommended level, apply the keratin formula avoiding direct scalp contact, allow processing time, then blow-dry and flat iron each strand to seal the treatment. Waiting up to 48 hours before shampooing helps the treatment settle into the hair structure.

• Wash with the clarifying shampoo only; skip conditioners or masks first.
• Dry hair to roughly 80% before applying the keratin product.
• Apply from mid-lengths to ends, leaving about a finger-width from the roots.
• Process 30–60 minutes, then dry and flat iron each section 15–20 times.

Will this treatment work on my hair type and how long do effects last?

The formula is designed for a wide range of textures—wavy, frizzy, or chemically treated hair can all benefit—though results vary by porosity, previous chemical history, and aftercare. With proper application and post-treatment maintenance, many users experience weeks to months of reduced frizz and straighter hair.

• Best for frizz-prone, wavy, or unruly hair seeking longer-lasting smoothness.
• Hair previously colored or relaxed may respond differently; strand testing recommended.
• Longevity depends on washing frequency, shampoos used, and exposure to humidity.
• Use sulfate-free maintenance products to extend the treatment effects.

Who is this for: Professionals and experienced users seeking a salon-caliber keratin straightening kit that supplies two 1L bottles for multiple applications. It's aimed at people who want a substantial reduction in daily heat styling and frizz, plus improved manageability for medium to long hair. If you are unsure about compatibility with prior chemical processes, perform a strand test or consult a stylist before full application.
