Preptonic is Lock Stock & Barrel's pre-styling tonic designed to solve a specific problem: hair that feels wispy, flat, and uncooperative straight out of the shower. Applied to towel-dried hair before any other styling product, it delivers a shot of volume, texture, and control that makes everything that comes after work harder and last longer. No stickiness, no flaking - just a fast-drying foundation that gives fine or thinning hair the backbone it needs.
- Format: Thickening Spray
- Hold: Light
- Finish: Natural
- Best For: Fine, thinning, or limp hair needing volume and styling control
Fine, thinning, or low-density hair that loses its shape quickly after washing. Also a smart addition to any styling routine that relies on volume - use it as a base layer before your clay, putty, or creme to amp up the result and extend hold throughout the day.
- Wheat protein complex strengthens and thickens each strand for immediate and cumulative volume
- PVP/VA Copolymer provides a lightweight, flexible structure that supports styling without stiffness
- Polyquaternium-10 conditions the hair and improves manageability, reducing static and frizz
- Fast-drying formula prepares hair for styling without leaving any residue or tackiness
- Works as a standalone light styler or as a base layer under heavier styling products
- Paraben free, cruelty free, and suitable for vegans
Carries Lock Stock & Barrel's warm signature fragrance - clean and refined, with a subtle aromatic character that sets the tone for the rest of your routine.
Spray onto towel-dried damp hair, applying section by section from root to tip. Work through with fingers and blow-dry or allow to air dry before applying any additional styling products.
Preptonic is one of those products that makes everything else in your routine perform better. It's the step most people skip — and once they add it in, they wonder how they managed without it. If fine or thinning hair is something you're working with, pairing Preptonic with Reconstruct Shampoo and Volumatte is a genuinely powerful combination worth building a routine around.
