Sarah K Carnival Brazilian Protein Kit – Frizz-Free Smoothing Treatment | 0% Formaldehyde

Sarah K Carnival Brazilian Protein Kit

A complete professional-grade Brazilian smoothing system — formulated without formaldehyde. The Carnival Protein is one of Sarah K’s most trusted treatments for volume reduction and frizz elimination, used in salons across Brazil and now available for home application. This kit includes everything needed for a full treatment cycle: the protein itself, a clarifying shampoo to prepare the hair, and a regenerative mask to finish and maintain results.

What’s in the kit

• Carnival Brazilian Protein (1L) — The core treatment. A volume reducer and straightening system that smooths the hair fiber and eliminates frizz. Built on a Volume Reducer Complex with 0% formaldehyde — safe for home use and suitable for chemically treated hair. Professional 1L size for full-head application with product to spare.
• Carnival & Rio Clarifying Shampoo — A deep-cleansing pre-treatment shampoo that removes product buildup, mineral deposits, and impurities from the hair before protein application. Essential for maximum protein penetration and longevity of results.
• Enjoy Regenerative Mask — A concentrated post-treatment mask with instant anti-volume and anti-frizz action. Formulated with keratin, collagen, amino acids, D-Panthenol, and vitamin B5. Repairs chemically damaged strands and extends the smoothing effect between treatments. Recommended for dry and damaged hair.

Key benefits

• 0% formaldehyde — Safe, odorless application without salon ventilation requirements
• Volume reduction — Significantly reduces bulk and thickness for easier styling
• Frizz elimination — Smooths the cuticle and seals the fiber against humidity
• Damage repair — Keratin and collagen in the mask rebuild weakened strands
• Professional quantity — 1L protein is a full salon-size supply, not a sample
• Complete system — Cleanse, treat, and maintain in one kit

What to expect

Results vary by hair type and texture. Coarse, thick, or very frizzy hair will see the most dramatic reduction in volume and frizz. Fine or already-straight hair will see smoothing and shine improvement. Results typically last 4–8 weeks with sulfate-free maintenance washing. Using the Rio Sulfate-Free Shampoo and Conditioner after treatment will significantly extend longevity.

Who it is for

• Curly, wavy, frizzy, or high-volume hair seeking smoothing and manageability
• Anyone who wants Brazilian protein results without formaldehyde
• Chemically treated, bleached, or damaged hair needing repair alongside smoothing
• Home users who want professional salon results without the salon visit

Who it is not for

• Fine, flat hair that doesn’t need volume reduction
• Anyone expecting permanent straightening — this is a smoothing and frizz treatment, not a relaxer
• Curly-girl method followers — the mask contains proteins that some curl methods avoid
