CHI Keratin Silk Infusion hydrating hair serum — 6 oz lightweight repair for dry, damaged hair, adds softness & shine

Formulated to strengthen fragile strands and improve manageability, CHI Keratin Silk Infusion blends keratin, silk proteins, and a reconstructing complex in a lightweight, sulfate-free serum. Designed for use on damp or dry hair, it helps smooth frizz, boost shine, and support elasticity without weighing hair down. This product arrives in a convenient 6 oz size suitable for at-home treatments and daily styling maintenance.

How does CHI Keratin Silk Infusion rebuild dry, damaged hair?

The serum delivers targeted protein support to areas of the hair shaft that have been weakened by heat, chemical services, or environmental stressors. Keratin helps reinforce the internal structure while silk proteins smooth the surface for improved slip and reflectivity.

• Keratin penetrates and strengthens the cortex for improved resilience.
• Silk proteins coat the cuticle to reduce friction and enhance shine.
• Lightweight reconstructing complex hydrates without heavy residue.

How should I use it during my routine for best results?

Apply a small amount to towel-dried hair before styling or use on dry hair to tame flyaways and add gloss. Work through mid-lengths to ends, comb gently to distribute product, and style as usual; it’s safe to pair with heat tools for added protection and smoother results.

• Use 1–2 pumps for short hair, more for longer or thicker hair.
• Apply to damp hair before blow-drying for smoothing and easier styling.
• Use on dry hair to add shine or control frizz between washes.

Will this serum weigh my hair down or leave buildup?

No — the formula is designed to be lightweight and non-greasy, so it adds moisture and slip without heaviness. Because it’s sulfate-free and formulated for leave-in use, it rinses cleanly during shampooing and won’t cause significant buildup when used as directed.

• Fast-absorbing texture for natural movement and volume retention.
• Non-sulfate formulation supports cleaner cleansing routines.
• Recommended amounts prevent over-application and residue.

Who is this for: CHI Keratin Silk Infusion is suited to anyone with dry, chemically treated, heat-styled, or brittle hair seeking a lightweight reparative serum to restore softness, add shine, and improve manageability. It’s beneficial for those who want professional-level smoothing and protection in an easy-to-use leave-in product, available in a travel-friendly 6 oz bottle for salon-quality care at home.
