CHI Keratin Silk Infusion Hydrating Hair Serum 6 oz — Sulfate-Free Repair & Shine for Dry, Damaged Hair

CHI Keratin Silk Infusion is a lightweight, sulfate-free hydrating serum that replenishes keratin and silk proteins to restore softness, strengthen strands, and boost shine.

Formulated by CHI (Farouk Systems), this leave-in reconstructing treatment blends keratin and silk amino acids to help repair the cuticle and improve manageability without weighing hair down. In a 6 oz bottle, the concentrated serum works on dry, chemically treated, or heat-styled hair to enhance elasticity, reduce roughness, and give a silkier appearance. Use it after washing or between styling sessions to smooth flyaways, add gloss, and protect hair from everyday stressors.

How does CHI Keratin Silk Infusion rebuild damaged hair?

The formula supplies keratin fragments and silk-derived proteins that bond to weakened areas of the fiber, helping to temporarily fill gaps in the cuticle and improve texture. It doesn’t change hair structure permanently but supports a smoother surface and better comb-through after application.

• Keratin and silk proteins reinforce and smooth cuticle edges.
• Lightweight oils and humectants add slip for easier detangling.
• Sulfate-free base reduces potential stripping during use with other products.

When and how should I apply this serum for best results?

Apply to towel-dried hair after cleansing for enhanced manageability, or use a small amount on dry lengths to tame frizz and add shine. Start with a pea-sized dose and increase as needed for thicker hair to avoid buildup.

• Post-shower: distribute from mid-lengths to ends, then style as usual.
• Between washes: smooth a tiny amount over flyaways and dull areas.
• Heat styling: apply before blow-drying to improve slip and finish.

What improvements can I expect without making claims?

Regular use typically results in softer-feeling hair with improved surface smoothness and a more radiant-looking finish. The serum helps hair appear healthier by reducing visible roughness and making styling easier.

• Enhanced manageability for easier brushing and styling.
• Noticeably smoother texture and reflective shine.
• Support for elasticity to minimize snapping during styling.

Is this product suitable for color-treated or chemically processed hair?

Yes — the sulfate-free formulation is designed to be compatible with color- and chemically treated hair, offering gentle care that won’t aggressively strip treatments. It pairs well with other CHI color-protecting products to maintain tone and surface condition.

• Sulfate-free to help preserve salon color and treatments.
• Non-greasy finish works across a range of textures and densities.
• Safe to layer with conditioners and styling sprays.

Who is this for: CHI Keratin Silk Infusion is aimed at anyone looking to improve the feel and finish of dry, brittle, or styled hair—especially those who use heat tools, chemical services, or need daily smoothing. It’s a practical leave-in step for users who want a lightweight reconstructing serum that adds slip, replenishes proteins, and enhances sheen without heavy residue. For best results, integrate into a routine with gentle cleansers and periodic deep-conditioning treatments suited to your hair type.
