CHI Keratin Silk Infusion lightweight leave-in serum, 2 fl oz — keratin repair & frizz control

CHI Keratin Silk Infusion is a lightweight leave-in reconstructive serum that replenishes keratin, smooths frizz, and helps seal the cuticle for shinier, stronger-looking hair.

Designed for hair weakened by heat styling, chemical services, or daily wear, this 2 fl oz treatment uses CHI's Keratrix sustained-release technology to deliver keratin protein and moisture over time. It works as a finishing or treatment product to improve manageability and restore silk-like softness without weighing hair down. Use after washing or between styles to refresh texture and reduce frizz.

How does CHI Keratin Silk Infusion rebuild damaged hair?

The formula contains keratin-enriching ingredients that help replenish protein lost from hair fibers. By sitting on and slightly penetrating the cuticle, it supports improved elasticity and reduced breakage during styling.

• Keratrix sustained-release system delivers keratin over time for ongoing support
• Targets keratin-depleted areas to enhance fiber resilience
• Lightweight serum consistency avoids heaviness or buildup

When and how should I apply the product for best results?

Apply to damp, towel-dried hair after cleansing or to dry hair as a finishing touch. Use a few drops distributed through mid-lengths and ends, then style as usual; it layers well under heat tools and other styling products.

• Post-shower: apply to damp hair before blow-drying for long-lasting smoothness
• Styling: apply a small amount to dry hair to tame frizz and add shine
• Refresh: use sparingly between washes to revive softness and manageability

Will this product work with color-treated or chemically processed hair?

Yes—CHI Keratin Silk Infusion is formulated to complement color and chemically treated hair by restoring lost protein and helping to seal the cuticle, improving look and feel without stripping color. It’s safe to combine with other salon treatments when used as directed.

• Supports hair integrity after coloring or chemical services
• Helps reduce surface roughness that can dull color shine
• Non-greasy finish preserves style and vibrancy

How much product should I use for different hair types?

Dosage varies by hair density and texture: a pea-sized drop for fine hair, a few drops for medium lengths, and a nickel-sized amount for thick or very long hair. Start small and add more where needed to avoid buildup.

• Fine hair: minimal amount to prevent weighing down
• Medium hair: moderate coverage through lengths and ends
• Thick/coarse hair: slightly larger dose focusing on damaged areas

Who is this for: CHI Keratin Silk Infusion is suited for anyone with keratin-depleted, dry, frizzy, or chemically treated hair seeking a lightweight reconstructive serum. It’s appropriate for salon clients and at-home users who want to improve softness, manageability, and shine while protecting hair during styling. Keep out of reach of children and follow directions on the packaging for best results.
