About Brazilian Nuts Keratin Duo
The Felps Brazilian Nuts Keratin Duo is a professional keratin smoothing treatment built for medium-curl, porous, frizzy hair that has been chemically processed. Its two-step Amazonian system delivers medium straightening while restoring elasticity and taming puffiness, so stylists can reshape unruly textures without flattening natural movement. Each application leaves the hair noticeably smoother, more manageable, and easier to style between salon visits.
The formula works by coating each strand in a protective keratin film while Brazil nut oil, fatty acids, and amino acids penetrate the cortex. These nutrients rebuild weakened areas, reduce porosity, and seal the cuticle for a sleek finish. The result is intensive nourishment paired with strong frizz control, adding shine and softness without the heaviness many smoothing systems leave behind.
What this treatment does
Delivers medium straightening that tames puffiness while keeping natural body
Seals the cuticle to reduce porosity and lock in moisture
Restores elasticity weakened by colour and chemical processing
Controls frizz and flyaways in high-humidity conditions
Replenishes the fibre with Brazil nut oil, fatty acids, and amino acids
Forms a protective film that adds shine without weighing hair down
How to use
Wash hair one to two times with the clarifying shampoo (Step 1) to strip buildup and prep the hair.
Blow-dry thoroughly until the hair is completely dry.
Apply the Keratin (Step 2) in a thin, even layer over each strand, keeping it off the roots for best results.
Leave the product to process for 30–45 minutes so it penetrates the hair structure, adjusting time to the hair’s texture.
Do not rinse.
Blow-dry to 100% dry.
Seal with a flat iron at the appropriate temperature, adjusted to the hair’s damage level.
