KEVIN.MURPHY Young.Again lightweight leave-in hair oil — 3.4 oz, heat protection to 450°F, strengthens & adds shine

KEVIN.MURPHY YOUNG.AGAIN is a lightweight leave-in hair oil that restores strength and adds luminous shine while protecting hair from heat up to 450°F.

Designed for all hair types, this leave-in treatment blends certified organic Immortelle with a nourishing base to improve elasticity and surface smoothness without weighing hair down. It functions as a multi-purpose finishing and repair oil: detangling, softening, and offering thermal protection for styling tools. The formula is cruelty-free, sulfate-free and paraben-free, making it a salon-grade option for everyday use or as an intensive boost for weakened strands.

How does YOUNG.AGAIN help damaged or brittle hair?

The oil targets signs of mechanical stress and surface roughness by delivering conditioning agents and antioxidants that support softer, more resilient hair. It seals the hair cuticle to reduce friction and breakage during combing and styling.

• Certified organic Immortelle to support hair repair and softness
• Lightweight conditioning that maintains natural bounce
• Reduces tangles and friction for gentler detangling

Will this product protect my hair while using heat tools?

Yes — YOUNG.AGAIN provides thermal protection up to 450°F when applied before blow-drying or heat styling. It forms a protective layer on the strand, helping reduce heat-related moisture loss and surface damage.

• Use on damp hair before blow-drying for best heat defense
• Suitable for flat irons, curling wands, and hot brushes
• Helps maintain smoothness and shine after styling

How do I incorporate this oil into my routine without weighing hair down?

A little goes a long way: dispense a small amount and emulsify in your palms before applying to mid-lengths and ends. For finer hair, use sparingly or as a finishing touch; thicker or drier hair can benefit from slightly more product or an overnight treatment.

• Apply 1–2 drops to fine hair; 3–4 drops for medium to coarse textures
• Use on damp hair before styling or on dry hair for shine and frizz control
• Can be layered under styling products without residue buildup

What makes this formula salon-quality and environmentally mindful?

• Paraben-free and sulfate-free formulation

Who is this for: YOUNG.AGAIN is suited to anyone seeking a versatile leave-in oil to improve manageability, protect against heat, and add healthy-looking shine. It's particularly useful for chemically treated, heat-styled, or naturally dry hair, as well as for users who want a lightweight, non-greasy finishing oil from a professional brand.
