KERAGEN Brazilian Keratin Smoothing Treatment for Fine to Medium Hair, 16 oz — Formaldehyde-Free

KERAGEN Brazilian Keratin Smoothing Treatment is a formaldehyde-free keratin blowout that smooths frizz, restores shine, and strengthens fine to medium hair for weeks after application.

Built on Brazilian-style salon techniques, this 16 oz treatment blends keratin and collagen to temporarily realign hair structure, reduce frizz, and improve manageability without harsh aldehydes. It’s formulated for fine to medium hair textures and designed to deliver smooth, glossy results with thermal reconditioning benefits when used with a flat iron.

How quickly will I see smoother, less-frizzy hair?

Most users notice reduced frizz and improved shine immediately after the in-salon or at-home smoothing process is completed. Full straightening and longevity become evident once the hair has been heat-sealed according to directions.

• Visible frizz control right after treatment and rinsing
• Smoother texture after heat sealing with a flat iron
• Results can last several weeks depending on hair care routine

Is this safe for chemically treated or colored hair?

The formula is free of formaldehyde and intended to be gentle enough for many color-treated or previously relaxed hair types, helping to strengthen and bond damaged areas. Always perform a strand test to confirm compatibility with existing treatments.

• Formaldehyde-free for milder application
• Keratn and collagen work to reinforce weakened strands
• Strand test recommended for bleached or heavily processed hair

What is the application process and maintenance routine?

Application follows a three-step approach: apply the smoothing solution, rinse and dry, then heat-seal with a flat iron to lock the result. After treatment, use sulfate-free shampoos and avoid saltwater or heavy chlorinated pools to extend duration.

• Apply evenly to clean, towel-dried hair and process per product guidelines
• Thoroughly dry and flat-iron small sections to seal the formula
• Maintain with gentle, sulfate-free products and limited washing

Which hair types get the best results from this treatment?

KERAGEN’s smoothing system is optimized for fine to medium hair textures that are frizzy, dry, or showing signs of breakage. It smooths cuticles and adds slip without over-weighting strands, delivering a silkier finish that’s easier to style.

• Best for fine to medium hair seeking smoother, straighter results
• Helps repair and fortify hair with keratin and collagen infusion
• Not recommended for very coarse hair expecting permanent straightening

Who is this for: This treatment suits anyone with frizz-prone, dry, or damage-affected fine to medium hair who wants a salon-quality smoothing result without formaldehyde. It’s appropriate for clients and at-home stylists looking to reduce styling time, enhance shine, and reinforce hair structure with a professional-grade keratin and collagen formula.
