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

Paul Mitchell Extra-Body Thicken Up Styling Liquid is a lightweight body-building styling liquid that makes fine strands look and feel thicker while leaving hair soft, shiny, and pleasantly scented.

This styling liquid is formulated specifically for fine hair to add volume, definition, and a touch of shine without weighing strands down. Its lightweight, non-greasy texture layers easily with other styling products and includes UV protection to help reduce visible damage from sun exposure. A luscious berry fragrance—notes of red raspberry, strawberry puree, and tropical fruit—leaves hair smelling fresh and inviting.

How does this styling liquid add fullness without feeling heavy?

The formula contains body-building ingredients that coat individual strands to create the appearance of greater diameter and lift at the roots. Because it’s a liquid rather than a cream or heavy mousse, it distributes evenly and dries without stiffness, leaving hair touchable and flexible.

• Lightweight liquid consistency for even coverage
• Coating action that visually thickens each strand
• Dries soft—no crunchy residue
• Works at roots and mid-lengths for overall volume

When and how should I use Paul Mitchell Thicken Up for best results?

Apply to clean, damp hair for the most noticeable lift; work it through roots to ends, then blow-dry or air-dry as usual. Stylists recommend using it before heat tools to boost body and maintain softness while styling.

• Use on damp, towel-dried hair for best lift
• Comb or finger-distribute from roots to ends
• Pair with a round brush and blow-dryer for extra root lift
• Layer under finishing sprays or texturizers if needed

Does this product protect hair while adding volume?

Yes—Thicken Up includes UV protection to help shield hair from the sun’s rays, which can contribute to faded color and surface damage. While not a replacement for dedicated treatments, the added UV protection helps preserve hair appearance when you’re out in the sun.

• Built-in UV protection to help guard against environmental stress
• Adds shine to enhance healthy-looking hair
• Non-greasy finish that maintains style movement
• Suitable for daily styling routines

What does it smell like and will the fragrance be overpowering?

The scent is a fruity berry blend with red raspberry, strawberry puree, and tropical fruit notes. It’s formulated to leave a pleasant, subtle fragrance on hair that fades naturally—noticeable but not overwhelming.

• Luscious berry aroma for a fresh finish
• Fragrance designed to be long-lasting yet unobtrusive
• Leaves hair smelling fresh without heavy perfume cling

Who is this for: Paul Mitchell Extra-Body Thicken Up Styling Liquid is ideal for people with fine or limp hair who want instant-looking thickness, root lift, and a soft sheen without weight. It suits color-treated and natural hair, and anyone seeking an easy-to-use, buildable product that plays well with heat styling and other finishing products. Packaging also reflects Paul Mitchell’s environmental goals, using post-consumer recycled materials where applicable—check local recycling rules for details.
