Joanne Jones Thickening Biotin & Collagen Leave-In Spray — 2-Pack Fresh Mint, Lightweight Volume & Strength

Joanne Jones Thickening Biotin & Collagen Leave-In is a lightweight, leave-on spray that adds volume, strengthens strands, and smooths frizz for fuller-looking hair.

This two-pack Fresh Mint leave-in spray combines biotin and collagen with a moisture-boosting formula to deliver salon-style body, manageability, and shine without weighing hair down. Designed for daily styling use, the spray detangles wet or damp hair, helps reduce breakage while you comb and style, and leaves a fresh mint scent. It’s free of parabens and harsh chemicals, cruelty-free, and made in the USA.

How does this leave-in build thicker-looking hair?

The formula pairs biotin and collagen to help strengthen individual strands and improve overall texture so hair appears fuller. It doesn’t change hair density overnight, but consistent use supports resilience and reduces the appearance of thinness by plumping and coating strands for added body.

• Biotin supports stronger hair fibers to reduce breakage during detangling and styling.
• Collagen helps give strands a thicker-feel by adding surface weight and smoothness.
• Weightless formulation boosts volume without leaving residue or stiffness.

Will this work with my hair type and styling routine?

This leave-in is formulated to be versatile across straight, wavy, curly, and coily textures; it provides moisture and slip for easier combing while supporting volume for fine to medium hair. Use it as part of the full Joanne Jones Thickening system for best results, or apply alone to boost manageability before blow-drying or air-drying.

• Apply to damp hair, concentrate on mid-lengths to ends, then comb through for even coverage.
• Suitable for daily use and safe with heat styling tools when used prior to drying.
• Works well layered with the matching shampoo and conditioner to enhance thickening effects.

How do I use the spray for maximum benefit?

Spray evenly onto damp hair, focusing on areas prone to tangling and thinness, then comb through to distribute the product from roots to ends. Do not rinse out: style as usual by air-drying or blow-drying to lock in volume, texture, and shine.

• Shake before use and hold the bottle 6–8 inches from hair for an even mist.
• Use more in problem areas like fine or flat roots, or less on already thick sections.
• Pair with heat protection if you frequently use high-temperature styling tools.

Is this product safe and salon-quality?

Joanne Jones formulates this leave-in to deliver professional results while avoiding harsh additives. The spray is paraben-free, cruelty-free, and crafted in the USA to meet salon-grade performance expectations without heavy residues or over-drying alcohols.

• Free of parabens and harsh chemical preservatives.
• 100% cruelty-free and produced under salon-quality standards.
• Light fresh mint scent leaves hair smelling clean without overpowering fragrances.

Who is this for: The Joanne Jones Thickening Biotin & Collagen Leave-In is ideal for anyone seeking fuller-looking hair, easier detangling, and natural-looking volume—especially those with fine to medium strands or anyone wanting lightweight moisture and manageability. If you prefer fragrance and a salon-feel while avoiding parabens and cruelty, this two-pack offers value for regular use as part of a volumizing hair routine.
