Paul Mitchell Extra-Body Thicken Up Styling Liquid — 5.1 oz Lightweight Volumizer for Fine Hair, Adds Fullness & Shine

Paul Mitchell Extra-Body Thicken Up Styling Liquid is a lightweight volumizing styling liquid that instantly makes fine hair look and feel thicker while adding softness, shine and UV protection.

Designed for fine, limp hair that needs lift without weight, this salon-grade styling liquid builds body and definition while preserving a natural finish. The formula leaves strands soft and glossy with a fruity berry fragrance and helps protect hair from UV exposure. Use it on clean, damp hair before drying or styling to amplify fullness and maintain movement.

How does Extra-Body Thicken Up create fuller-looking hair?

The product deposits lightweight film and polymers that coat individual strands, increasing diameter and the appearance of density without stiffness. It layers well under heat styling and other products, so you can boost volume without creating flake or crunch. The result is visibly plumper hair that still feels flexible.

• Lightweight body-building agents that thicken each strand
• Non-greasy finish that avoids weighing hair down
• Compatible with blow-drying and thermal styling tools

Will this styling liquid weigh my hair down or leave residue?

No — the formulation is specially balanced for fine hair so it adds lift without heaviness or tack. It rinses clean and won’t leave a waxy coating when used as directed on damp hair. For best results, apply sparingly at roots and distribute through lengths before styling.

• Feather-light texture suitable for thin, fragile strands
• Non-stiff hold that preserves natural movement
• Rinseable formula that avoids buildup with normal washing

How and when should I apply Thicken Up for the most noticeable volume?

Apply to freshly washed, towel-dried hair for the most effective body boost. Work a small amount into roots and mid-lengths, then blow-dry using a round brush or diffuser to lift and set the added fullness. You can reapply a tiny amount on dry hair to refresh shape without rewetting.

• Use on clean, damp hair for maximum lift
• Focus product at the scalp and mid-lengths for root-to-tip volume
• Style with heat to lock in body and smooth shine

Does this product offer any protection or scent worth noting?

Extra-Body Thicken Up includes UV protection to help reduce sun-related damage and fading during regular styling and outdoor exposure. It also leaves a pleasant fragrance of red raspberry, strawberry puree and tropical fruit that lingers subtly without overpowering. The packaging has been updated with post-consumer recycled materials as part of Paul Mitchell’s sustainability efforts.

• Built-in UV shield to protect hair fiber from sun exposure
• Luscious berry scent blending raspberry, strawberry and tropical notes
• Retail packaging moving to post-consumer recycled components
