KEVIN.MURPHY Body Mass leave-in thickening treatment 3.4 oz — weightless volume & strengthening

BODY.MASS by KEVIN.MURPHY is a leave-in thickening treatment that strengthens strands and lifts fine hair to create visible body and bounce.

Designed as a professional-strength, weightless leave-in, BODY.MASS targets fine, limp, or chemically-stressed hair to improve resilience and add fullness without stiffness. The 3.4 oz size is ideal for regular at-home use or to trial the formula that stylists rely on for creating thicker-looking styles. It’s color-safe and formulated without sulfates or parabens, offering a gentle option for many hair types while aligning with KEVIN.MURPHY’s environmentally conscious approach.

How does BODY.MASS add volume to thin hair?

BODY.MASS works on both the hair shaft and the scalp-level support system to make strands appear thicker and give styles more lift. Lightweight conditioning agents smooth the cuticle while active botanicals help strengthen the fiber, so hair holds shape better without feeling heavy.

• Leave-in formula that builds texture without residue
• Contains fortifying ingredients to enhance strand thickness
• Balances manageability with long-lasting body

Will this product help damaged or color-treated hair?

Yes — BODY.MASS is formulated to be color-safe and gentle, helping to improve the look of distressed or chemically-treated hair. The treatment replenishes and conditions while supporting the hair’s structure, so color-treated strands retain vibrancy and bounce.

• Safe for color-treated hair and free from harsh sulfates
• Helps smooth and detangle weakened areas
• Regular use helps reduce the appearance of breakage and frizz

How do I use BODY.MASS for best results?

Apply a small amount to damp, towel-dried hair from mid-lengths to ends, and distribute evenly with your fingers or a wide-tooth comb. Style as usual — air-dry or blow-dry — and reapply lightly on dry hair where extra lift or texture is needed.

• Use sparingly at first; a little spreads far on fine hair
• Combine with volumizing shampoos and conditioners for maximum effect
• Works under styling products and heat tools without weighing hair down

Is BODY.MASS cruelty-free and what are the key formulation points?

KEVIN.MURPHY formulates BODY.MASS without sulfates or parabens and adheres to cruelty-free practices. The blend focuses on strengthening actives and conditioning emollients that deliver texture and resilience while minimizing harsh chemicals.

• Sulfate-free, paraben-free formula suitable for regular use
• Cruelty-free brand philosophy and salon-grade performance
• Designed for everyday styling as a lightweight reparative treatment

Who is this for: BODY.MASS is ideal for people with fine, limp, or chemically-processed hair who want to add visible thickness and manageability without stiffness. It suits those seeking a salon-quality leave-in that supports styling, color longevity, and a fuller hair look while adhering to milder ingredient preferences.
