CHI Infra Thermal Protective Hair Serum — 6 oz Color-Protecting, Lightweight Heat Protectant for Shine & Softness

CHI Infra Thermal Protective Treatment is a sulfate-free hair serum that shields color, smooths cuticles, and adds lasting shine and softness.

This lightweight, hydrating formula uses CHI’s Infra technology with ceramic and cationic hydration to penetrate and reinforce the hair shaft. Infused with positively charged silk molecules, the serum locks moisture into the hair’s inner structure, improving strength, elasticity and manageability without weighing strands down. Designed for use before heat styling or as a finishing serum, it helps reduce damage while enhancing radiance.

How does this treatment protect color while styling?

The formula forms a protective layer that helps prevent color fade from heat exposure and environmental stressors without adding heavy residue. It minimizes cuticle disruption, so treated hair retains vibrancy longer between salon visits.

• Uses CHI 44 Ceramic to distribute gentle infrared heat.
• Cationic Hydration Interlink to lock moisture inside the hair shaft.
• Lightweight barrier reduces direct heat contact during styling.

Will it make my hair feel soft without becoming greasy?

Yes — the serum is designed to enhance silkiness and smooth flyaways while remaining non-greasy when applied appropriately. A small amount concentrated on mid-lengths and ends delivers slip and shine without weighing roots down.

• Positively charged silk molecules integrate into each strand for lasting softness.
• Sulfate-free formula that avoids strip-dry effects common with harsher cleansers.
• Works on damp or dry hair as a primer or finishing touch.

How do I use it in my routine for best results?

Use after shampooing and conditioning or apply a small pump to damp hair before blow-drying and flat-ironing. It can also be used sparingly on dry hair to tame frizz and add mirror-like shine as a finishing serum.

• After washing: distribute evenly, leave 2–5 minutes, then rinse for treatment benefits.
• Before heat styling: smooth through damp hair to protect against heat damage.
• On dry hair: apply a pea-sized amount to ends to control frizz and boost gloss.

Is it suitable for treated, damaged, or color-treated hair?

Absolutely — the product is formulated for hair that needs rebuilding and moisture retention. Its gentle, conditioning profile improves resilience and gives color-treated hair a smoother appearance.

• Strengthens the inner structure to improve elasticity and reduce breakage.
• Free of sulfates and parabens, making it gentler on processed hair.
• Cruelty-free formulation consistent with CHI brand standards.

Who this is for: Ideal for anyone with color-treated, heat-styled, or dry hair seeking a lightweight serum that both protects and beautifies. If you want a multi-purpose product that conditions, defends against thermal damage, and increases shine without buildup, CHI Infra Thermal Protective Treatment is formulated to fit into daily styling and weekly haircare routines.
