CHI Keratin Silk Infusion Hydrating Hair Serum — 6 oz, Leave-In Repair, Frizz Control & Shine

CHI Keratin Silk Infusion is a leave-in hydrating serum that replenishes keratin and silk proteins to smooth, strengthen, and add long-lasting shine to dry or damaged hair.

This lightweight, non-sulfate formula combines keratin and silk-derived ingredients to rebuild weakened strands, seal the cuticle, and improve manageability without weighing hair down. Designed as a finishing treatment or a mid-week booster, it smooths frizz, reinforces elasticity, and helps protect hair from styling stress. Easy to apply and suitable for multiple hair types, the serum can be used on damp or dry hair to enhance shine and reduce tangles.

How does CHI Keratin Silk Infusion rebuild damaged hair?

The serum delivers keratin-based proteins that temporarily fill gaps in the hair shaft and silk-derived ingredients that smooth the surface, restoring a softer feel and more uniform reflectivity. Regular use helps hair appear fuller and more even while reducing the look of split ends.

• Keratin proteins bond to weakened areas to add structural support
• Silk-derived components smooth cuticle scales for enhanced shine
• Lightweight formulation avoids greasy buildup or limpness
• Seals fiber surface to reduce snagging and frizz

When and how should I use this hydrating hair serum?

Apply a small amount to towel-dried hair before styling or to dry hair as a finishing touch to tame flyaways and boost shine. Start with a dime-to-quarter-sized amount depending on hair length and texture, and distribute evenly from mid-lengths to ends.

• Use on damp hair before blow-drying for smoother styling
• Apply sparingly on dry hair to add shine and control frizz
• Compatible with heat styling to help reduce breakage during styling
• Safe for color-treated and chemically processed hair when used as directed

Will this product make my hair feel heavy or greasy?

No: the formula is designed to be lightweight so it delivers hydration and slip without weighing hair down. Properly dosed, it leaves hair soft, manageable, and touchable rather than oily.

• Non-greasy texture that absorbs quickly
• Works well with layering other styling products
• Helps detangle without buildup when used moderately
• Rinsing is not required—designed as a leave-in treatment

Who is this for? CHI Keratin Silk Infusion is suited for anyone with dry, brittle, chemically treated, or heat-stressed hair who wants a simple leave-in solution to improve softness, reduce frizz, and add reflective shine. It’s also a practical pick for people who regularly style hair with heat tools, color-treated hair, or those looking to extend the life of a smoothing treatment. If your hair needs focused hydration and easier manageability without heavy residues, this serum is formulated to fit into your routine.
