THORN & BERRY Leave-In Conditioner for Fine Hair — Rosemary Mint Ultra-Lightweight Detangling & Hydrating Spray

THORN & BERRY Ultra-Lightweight Biotin Leave-In Conditioner is a water-based detangling spray that adds hydration, strength, and slip to fine, fragile, and chemically treated hair without weighing it down.

This fast-absorbing leave-in mist is formulated for hair that needs moisture, manageability, and resilience—think fine, curly, heat-damaged, color-treated, or thinning strands. It blends biotin, caffeine, rice protein, ceramides, and lightweight oils with rosemary and mint extracts for a balancing, fresh-feeling finish. Designed to be sprayed on damp or dry hair, it reduces knots, smooths frizz, and supports styling routines without greasy buildup or stiffness.

How does this leave-in conditioner help detangle and protect fragile hair?

The spray creates immediate slip so brushes and fingers glide through tangles with less force, helping prevent breakage. Its mix of hydrolyzed proteins and panthenol smooths the cuticle while ceramide NP and squalane add lightweight moisture for elasticity.

• Instant detangling for wet or dry hair to minimize pulling and split ends
• Hydrolyzed rice protein and keratin strengthen brittle strands
• Panthenol and ceramides lock in moisture without residue
• Leaves hair softer and easier to style after one use

Will this work on fine or thin hair without making it flat?

Yes—its water-based formula and featherlight oils were selected to hydrate without coating strands. The mist absorbs quickly, giving body and movement rather than a weighed-down finish, so styles retain natural lift.

• Non-greasy, fast-absorbing base suitable for fine textures
• Biotin and niacinamide for appearance of fuller, healthier hair
• No heavy silicones or thick creams that compress volume
• Safe for daily use, refreshes between washes

What active ingredients are included and what do they do?

A balanced blend of strengthening, soothing, and hydrating ingredients supports hair resilience and scalp comfort. Actives are chosen to work together: proteins and amino acids reinforce the shaft while botanical extracts calm and refresh.

• Biotin and hydrolyzed keratin for strand reinforcement
• Caffeine and niacinamide to stimulate scalp circulation and vitality
• Rosemary, peppermint, chamomile, and aloe for a clean, calming scent and soothing feel
• Vitamin E, argan oil, and squalane to add shine without heaviness

How should I use this spray to fit my routine?

Spray on damp hair after washing to detangle and prepare for styling, or mist dry hair anytime for refresh and frizz control. It layers well under heat protectors or styling creams and can be used on natural hair, braids, wigs, and extensions.

• Apply 4–8 inches from hair, focusing on mid-lengths and ends
• Comb or finger-detangle gently after spraying to reduce snapping
• Use a light mist for daily refreshes or a fuller spray post-wash
• Travel-friendly for quick midday hydration and static control

Who is this for: THORN & BERRY Ultra-Lightweight Biotin Leave-In Conditioner is aimed at anyone with fine, brittle, chemically treated, curly, or aging hair seeking a no-residue, strengthening detangler. It’s also a practical choice for people who wear wigs, braids, or extensions and need a gentle, hydrating mist that restores softness and eases styling without sacrificing bounce or texture.
