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

CHI Keratin Silk Infusion is a lightweight keratin-enriched leave-in treatment that smooths frizz, strengthens damaged strands, and restores shine.

What started as a salon-grade solution is now available in a 2 fl oz bottle for at-home maintenance: a lightweight serum formulated with Keratrix technology to replenish keratin protein, seal the cuticle and deliver everyday protection and hydration. The formula absorbs quickly without weighing hair down, making it suitable for styling routines that need a polished, resilient finish.

How does this treatment rebuild weakened, keratin-depleted hair?

The product supplies targeted keratin-building ingredients designed to penetrate the hair shaft and support elasticity. Over time, treated hair resists breakage better while appearing smoother and more uniform in texture.

• Keratrix technology releases conditioning agents gradually for ongoing repair.
• Replenishes proteins to reduce tangling and split-end appearance.
• Seals the cuticle to lock in moisture and minimize surface roughness.

Will it weigh fine hair down or leave a greasy finish?

CHI Keratin Silk Infusion is formulated to be lightweight and fast-absorbing so it won’t typically make fine hair look limp. Use a small pump and apply from mid-lengths to ends; adjust amount based on porosity and styling needs.

• Silky serum texture disperses evenly for balanced coverage.
• Quick absorption reduces residue and maintains natural movement.
• Suitable as a pre-styling or finishing step for most hair types.

How do you use it within a daily styling routine?

Apply to damp or dry hair to smooth, protect and add shine before heat styling or as a finishing polish. A little product goes a long way—focus on damaged areas or ends, then comb through for even distribution.

• Apply 1–2 drops to fine hair, more for medium to thick textured hair.
• Use before blow-drying to improve manageability and reduce frizz.
• Apply sparingly after styling to tame flyaways and enhance gloss.

What results can you expect and how soon?

Many users notice smoother texture and increased shine after the first application, with cumulative strengthening and improved elasticity from regular use. Results depend on hair condition and complementary care routines.

• Immediate: visible smoothing and reduced surface frizz.
• Short term: improved detangling and softer feel after repeated use.
• Ongoing: stronger-looking strands as the formula supports keratin balance.

Who is this for: CHI Keratin Silk Infusion is designed for anyone with dry, frizzy or chemically treated hair seeking a salon-grade protein boost in a compact bottle. It’s ideal for users who want to strengthen strands, smooth texture and add shine without a heavy finish—especially useful for at-home maintenance between professional keratin services or for daily styling protection.
