CHI Keratin Silk Infusion Hydrating Leave-In Hair Serum, 6 oz — Restores Softness & Shine, Sulfate-Free

CHI Keratin Silk Infusion is a leave-in hydrating serum that restores softness and shine by replenishing keratin and silk proteins to dry, damaged hair.

Formulated by CHI (Farouk Systems), this lightweight reconstruction serum blends keratin and silk-derived ingredients to help strengthen strands, smooth cuticles, and improve manageability without weighing hair down. It’s sulfate-free and designed as a leave-in treatment to deliver ongoing hydration and protection between washes while enhancing hair’s natural feel and gloss.

How does CHI Keratin Silk Infusion repair damaged hair?

The formula supplies keratin-building ingredients that target weakened areas of the strand and silk proteins that smooth surface fibers for a softer texture. Over time, repeated use supports improved elasticity and reduced appearance of roughness without harsh surfactants.

• Keratin-enriched complex replenishes structural proteins.
• Silk proteins smooth and add slip to reduce friction.
• Sulfate-free base avoids stripping natural oils.
• Lightweight leave-in application for continuous benefit.

Will this serum make my hair feel heavy or oily?

No — CHI’s infusion is formulated to be lightweight so it hydrates without build-up when used as directed. A small amount applied to mid-lengths and ends delivers shine and manageability while leaving roots free of residue.

• Use a pea-to-dime sized amount depending on length and thickness.
• Apply mainly to mid-lengths and ends, avoid scalp if prone to oiliness.
• Works well under heat styling to smooth and protect.

How should I use this product in my routine?

After towel-drying, distribute a small amount through damp hair, concentrating on ends and any fragile sections. It can also be used sparingly on dry hair to tame frizz and add instant shine before styling.

• Apply to damp hair for best penetration and manageability.
• Combine with regular CHI shampoo/conditioner for a complete regimen.
• Use before heat styling to improve slip and reduce friction.
• Reapply lightly on dry hair for quick shine touch-ups.

What results can I realistically expect and when?

Immediate benefits include smoother texture, easier detangling, and visible shine; structural improvements such as better elasticity and fewer split ends develop with consistent use. Results depend on hair condition, frequency of use, and styling habits.

• Instant: increased shine and reduced frizz after first application.
• Short term: easier styling and improved manageability within weeks.
• Long term: stronger-feeling hair and reduced breakage with regular use.

Who is this for: CHI Keratin Silk Infusion suits anyone with dry, chemically treated, heat-styled, or naturally coarse hair seeking a lightweight reconstructive treatment. It’s a practical option for people wanting to improve softness, protect hair during styling, and support healthier-looking strands without silicones that create heavy buildup. Ideal for salon users, at-home stylists, and anyone looking to add keratin and silk benefits into their everyday haircare routine.
