ORIBE Hair Alchemy Treatment Serum — 5.9 oz Strengthening Leave-In, Heat Protection to 450°F

Oribe Hair Alchemy Treatment Serum is a leave-in strengthening serum that reinforces fragile hair, increases elasticity and provides heat protection up to 450°F for softer, more resilient strands.

This lightweight, fast-absorbing treatment uses a Multi-Action Hyaluronic Acid Complex and plant-derived extracts to restore moisture, reduce breakage from brushing and styling, and support length retention over time. Formulated free of silicones, sulfates and phthalates, it is color- and keratin-treatment safe, vegan and cruelty-free. The serum also carries Oribe’s signature Côte d’Azur scent—bright bergamot, jasmine and warm sandalwood—so hair smells as polished as it performs.

How does this serum protect hair from heat and styling damage?

The formula creates a protective layer around the hair fiber to shield against thermal stress and mechanical abrasion caused by combing, brushing and hot tools. It’s designed to reduce the micro-tears that lead to split ends and weakened strands during routine styling.

• 450°F heat protection for styling tools
• Lightweight barrier that reduces friction during brushing
• Supports fewer breakage points so strands remain intact longer

What ingredients improve strength and elasticity?

A targeted hyaluronic acid complex attracts and holds moisture inside the hair, while Cotton Seed Extract helps enhance flexibility so fibers bend instead of snapping. Together they hydrate, soften and reinforce hair from the cortex outward.

• Multi-Action Hyaluronic Acid Complex for moisture retention
• Cotton Seed Extract to support elasticity and reduce breakage
• Clinically measured improvements in elasticity and tensile strength when used as a system

How should I apply the serum for best results?

Use on damp, towel-dried hair from mid-lengths to ends, and comb through to distribute evenly. It can be used before blow-drying, flat-ironing or air-drying; a small amount is enough thanks to the fast-absorbing texture.

• Apply a pea- to dime-sized amount for short hair; more for longer or thicker hair
• Work through mid-lengths and ends, avoid root buildup
• Combine with Oribe Hair Alchemy Shampoo and Conditioner for optimal strength gains

Is this safe for treated or color-treated hair?

The serum is formulated to be color- and keratin-treatment safe and is dermatologist tested. It’s free from silicones, sulfates and phthalates, and is PETA-approved vegan and cruelty-free.

• Color-safe and compatible with keratin treatments
• Vegan, silicone-free, sulfate-free and phthalate-free
• Dermatologist tested and cruelty-free certified

Who is this for: Oribe Hair Alchemy Treatment Serum is suited to anyone with fragile, thinning or frequently styled hair who wants to reduce breakage, improve softness and protect strands from thermal and mechanical damage. It’s especially useful for people seeking a lightweight, non-greasy leave-in that layers well with other styling products and complements professional salon care.
