INFUSIUM 23 Pro-Vitamin Leave-In Hair Treatment 33.8 oz — Original Formula, Lightweight Detangling & Heat Protection

INFUSIUM 23 Original Formula Pro-Vitamin Leave-In Hair Treatment is a lightweight, leave-in conditioning spray formulated with pro-vitamin B5 to detangle, strengthen, and protect hair without weighing it down.

This 33.8 fl oz (1 L) professional-size bottle offers a classic, easy-to-use solution for hair that needs everyday smoothing, heat protection, and manageable shine. The formula absorbs quickly to repair cuticle layers, reduce friction during styling, and leave hair soft and combable. It’s designed for repeated use on damp or dry hair and works across hair types looking for a lightweight boost rather than heavy coating.

How does this leave-in help with tangles and styling?

The pro-vitamin B5–infused formula smooths hair fibers to reduce knotting and friction, making combing and styling faster and gentler. It aids heat styling by creating a smoother surface for tools to glide over, reducing breakage during blow-drying or flat ironing.

• Instant detangling action for wet or dry hair
• Reduces styling time by smoothing the cuticle
• Lightweight spray that won’t leave sticky residue

Will this weigh my hair down or leave buildup?

The Original Formula is formulated to penetrate and condition without heavy oils or waxy residues, so it won’t flatten hair volume when used as directed. Regular use on damp hair provides hydration and manageability while maintaining natural movement and body.

• Non-greasy, fast-absorbing texture
• Designed for daily leave-in use without residue
• Helps preserve natural bounce and lift

Can INFUSIUM 23 repair damaged or chemically treated hair?

This leave-in supports the appearance of healthier hair by helping to reinforce cuticle layers and improve the hair’s surface smoothness. While not a clinical repair treatment, it helps reduce the visible effects of breakage and makes hair easier to manage after chemical or heat exposure.

• Pro-vitamin B5 helps strengthen strands over time
• Improves combability to minimize mechanical damage
• Works well alongside color-safe and restorative shampoos

How should I use it for best results?

Spray evenly on towel-dried or dry hair, focusing on mid-lengths and ends, then comb through to distribute. You can let hair air-dry for a softer finish or style with heat tools for a sleeker look; reapply lightly on dry hair for extra control as needed.

• Use on damp hair after shampoo and conditioner
• Comb through to ensure even coverage
• Reapply sparingly on dry hair for touch-ups

Who is this for: INFUSIUM 23 Original Formula Pro-Vitamin Leave-In Hair Treatment is ideal for anyone seeking an affordable, professional-strength leave-in that detangles, smooths, and protects without heaviness. It’s especially useful for people with dry, frizzy, color-treated, or heat-styled hair who want everyday manageability and improved surface condition. Salon professionals, busy households, and those who prefer a single, versatile product for both wet- and dry-styling will find the 33.8 oz size convenient and long-lasting.
