Nécessaire Rosemary Conditioner — Multi-Protein Strengthening Conditioner, 250 ml, Color-Safe & Sulfate-Free

Nécessaire Rosemary Conditioner is a multi-protein strengthening daily conditioner designed to support stronger, more resilient hair with pure rosemary and plant-derived proteins.

This lightweight gel-cream conditioner combines rosemary (oil, extract and water), botanical emollients, essential ceramides and a blend of plant proteins to condition, detangle and help improve hair resilience without sulfates, silicones, parabens, PEGs or phthalates. The formula is color-safe, dermatologist-tested and created for everyday use, offering a soft herbal-mandarin fragrance that pairs rosemary with jasmine and cedar.

How does this conditioner help hair that feels thin or fragile?

The Rosemary Conditioner uses multiple plant proteins and ceramides to reinforce hair fiber and reduce breakage from detangling. Its gel-cream texture smooths cuticles for easier comb-through and helps hair appear fuller by improving manageability and bounce.

• Multi-protein blend targets weakened strands for improved strength.
• Essential ceramides help support the hair surface and reduce friction.
• Detangling texture lowers mechanical breakage when combing.

Is it safe for color-treated or sensitive scalps?

This conditioner is formulated without common harsh additives and is safe to use on color-treated hair. Dermatologist-tested, hypoallergenic and non-comedogenic, it’s designed to be gentle on sensitive scalps while still delivering conditioning benefits.

• Free of sulfates, silicones, parabens, PEGs and phthalates.
• Color-safe formulation preserves dyed hair vibrancy.
• Hypoallergenic and dermatologist-tested for everyday use.

What does the scent profile feel like in daily use?

The fragrance is subtle and refined, centering on rosemary with bright mandarin top notes and soft floral and cedar undertones. It’s designed to be a fine, non-overpowering scent that leaves hair smelling fresh without lingering heaviness.

• Herbal rosemary core for a clean, green aroma.
• Mandarin adds a light, citrus lift to each wash.
• Jasmine and cedar round out a calm, spa-like finish.

How should I use the conditioner for best results?

Apply to cleansed, towel-dried hair focusing on mid-lengths to ends; leave for one to three minutes before rinsing for easier detangling and added resilience. Use daily or as part of your regular routine; adjust application amount to hair length and thickness.

• After shampooing, distribute evenly through towel-dried hair.
• Leave in for 1–3 minutes for light conditioning, longer for extra slip.
• Rinse thoroughly; follow with styling as usual.

Who is this for? The Nécessaire Rosemary Conditioner is intended for anyone seeking a gentle, daily-strengthening conditioner—men and women, all hair types and textures, and those with color-treated or sensitive scalps. It suits people who prefer plant-forward formulations and lightweight conditioning that improves manageability and resilience without heavy silicones or typical harsh additives.
