Paul Mitchell Extra-Body Thicken Up Styling Liquid, 5.1 oz — Lightweight Volume & UV Protection

Paul Mitchell Extra-Body Thicken Up is a lightweight styling liquid that visibly thickens fine hair while adding shine and a soft, touchable finish.

This styling liquid is formulated to give limp, fine strands a fuller appearance without weighing hair down. It layers easily under blow-drying or air-drying routines, delivers a pleasant berry fragrance, and includes UV protection to help guard hair from sun exposure. The texture stays light and manageable so you can achieve body and definition without stiffness.

How does this product make fine hair look fuller?

The formula coats each strand to increase diameter perception and lift at the roots, producing an overall denser look. Rather than heavy oils or waxes, it uses a thin, spreadable liquid that builds volume without stickiness, so hair remains soft to the touch.

• Lightweight body-building formula targets thin strands
• Even, film-forming coverage increases strand thickness visually
• Root lift for better long-term volume when blow-dried

When and how should I use Extra-Body Thicken Up for best results?

Apply to clean, damp hair for the most consistent lift and shine. Work the liquid through roots to ends, then style with a blow-dryer or let hair dry naturally; layering with heat tools enhances fullness and definition.

• Use after shampooing on towel-dried hair
• Distribute from roots to mid-lengths for added lift
• Finish with blow-dry or air-dry depending on desired texture

Does it affect hair feel, scent, or sun exposure?

The product is formulated to leave hair soft with a light sheen rather than a heavy or crunchy finish. It carries a fruity berry scent featuring raspberry, strawberry puree and tropical notes, and contains UV protection to help reduce oxidative stress from sunlight.

• Soft, touchable finish — not stiff or greasy
• Luscious berry fragrance for a fresh, fragrant style
• UV protection adds a layer of environmental defense

How does Paul Mitchell approach packaging and sustainability?

Paul Mitchell is transitioning retail packaging to include post-consumer recycled (PCR) content and simplified caps and labels for easier recycling. This product is part of that effort, reflecting the brand’s emphasis on reducing environmental impact across its supply chain.

• Bottles and jars moving to 30–50% PCR by 2026 (retail sizes)
• Tubes planned with 25% PCR content by 2026
• Some components like pumps and select caps remain virgin plastic

Who is this for: Extra-Body Thicken Up is designed for people with fine or limp hair who want noticeable volume without heavy residue. It’s a good option for anyone seeking a lightweight styling aid that enhances body, adds gloss, and leaves hair feeling soft and fragrant. Ideal for daily styling routines or special-occasion blowouts where fuller-looking hair is the goal.
