KERATIN RESEARCH Brazilian Keratin Hair Smoothing Treatment 4 oz — Professional, Long‑Lasting Frizz Control

KERATIN RESEARCH Brazilian Keratin is a professional-grade 4 oz smoothing treatment that delivers up to 4–6 months of straighter, shinier, frizz‑reduced hair with a natural finish.

This salon-style keratin formula combines keratin proteins, argan oil, and collagen amino acids to smooth, strengthen, and repair hair from the inside out. Designed for use at home or in professional settings, the concentrated 120 ml (4 oz) bottle treats most hair lengths; those with very long or thick hair may prefer two bottles or the 10 oz option. The product focuses on lasting manageability rather than temporary masking, helping reduce daily styling time.

How long will the smoothing effect last and what affects longevity?

Results typically persist for 4–6 months depending on hair porosity, washing frequency, and aftercare. Using gentle, sulfate‑free shampoos and avoiding excessive heat or chlorine will extend the smooth, frizz‑free appearance.

• Expect 4–6 months on average.
• Sulfate‑free products help preserve results.
• Heavy sun, chlorine, and frequent washing shorten duration.
• Touch‑ups or a second bottle recommended for very long/thick hair.

What hair types and issues can this treatment address?

This KERATIN RESEARCH formula works across a wide range of textures—wavy, curly, frizzy, coarse, and chemically treated hair respond well. It targets breakage, rough cuticles, and frizz by infusing keratin and conditioning agents, improving appearance and manageability without creating an artificial rigid look.

• Smooths frizz and reduces styling time.
• Strengthens and repairs weakened strands.
• Suitable for color‑treated and permed hair when used as directed.
• Produces a natural, flexible straightening effect rather than a ceramic‑hard finish.

How is the treatment applied and what should I expect during use?

Application follows simple, step‑by‑step instructions for either salon or at‑home use: cleanse, apply treatment evenly, then seal with heat as directed. The formula is concentrated, so precise application and heat sealing deliver the best, long‑lasting result; support is available if you have questions about technique.

• Includes one 120 ml (4 oz) treatment bottle.
• Apply to clean, towel‑dried hair and distribute evenly.
• Seal with a flat iron per instructions for optimal longevity.
• Contact responsive support for product or technique help.

What safety and aftercare should I follow?

Follow the included instructions and recommended ventilation during application. Aftercare focuses on sulfate‑free cleansing and protection from harsh environmental exposures to maintain the result and hair health.

• Use gentle, sulfate‑free shampoos to preserve treatment.
• Avoid chlorine and long sun exposure when possible.
• Combs and heat styling should be gentle to avoid breakage.
• Follow any stylist guidance for color or chemical service timing.

Who is this for: KERATIN RESEARCH Brazilian Keratin 4 oz is ideal for people seeking salon-quality smoothing without a rigid synthetic look—those with frizzy, wavy, or chemically treated hair who want easier daily styling, reduced breakage appearance, and up to several months of manageability. Choose two bottles or the larger size if your hair is very long, extra thick, or if you plan multiple applications.
