Why You’ll love it

Turn flat, fine hair into fuller-looking strands you actually want to touch.

Adds weightless thickness from roots to tips, without sticky build-up.

Leaves hair soft, moveable and glossy, never stiff or crunchy.

Helps your blow-dry hold its shape, even on longer days.

Description

Paul Mitchell Extra-Body Thicken Up is a lightweight styling gel that boosts fullness and shine.

This body-building formula coats each strand to create the look of thicker, plumper hair without stiffness. It works by adding flexible volume and memory, helping your style stay lifted and defined throughout the day.

The texture feels like a smooth, non-sticky gel that glides easily through damp hair. Once dry, hair feels touchably soft with a clean, glossy finish and no crunchy residue.

Ideal for fine to medium hair that falls flat, it’s perfect for daily blow-drying, round-brush styling, or air-drying with added oomph. Your hair looks more lifted at the roots, feels more substantial through the lengths, and appears brighter and more polished.

Directions

How To Use Paul Mitchell Extra-Body Thicken Up

Apply 1–3 pumps to clean, towel-dried hair.
Work evenly from roots to ends with fingers or comb.
Blow-dry with a round brush for maximum lift and thickness.
For a softer look, scrunch in and allow hair to air-dry.
Use a small amount on dry hair to smooth and add shine.

Film-forming styling polymer

A film-forming polymer that helps provide hold, texture and style retention.

May suit
People looking for longer-lasting hold or improved definition in styling products.

Worth knowing
It is widely used in gels, mousses and sprays because it creates flexible, brushable hold. It can also help reduce frizz by forming a lightweight coating on the hair.
PVP Thickeners and stabilisers

Film-forming polymer

PVP is a film-forming ingredient that helps provide hold and structure in styling products.

May suit
Anyone looking for longer-lasting hold, enhanced definition or improved style memory.

Worth knowing
It is widely used in gels, mousses and sprays because it creates a flexible film on the hair shaft. Its performance can vary with humidity, so it is often blended with other polymers for stability.

Styling polymer

A film-forming polymer that helps provide hold, shape and frizz control in styling products.

May suit

Silicone-based conditioning agent

A water-dispersible silicone that helps soften hair, add slip and reduce frizz.

May suit
People looking for smoother, easier-to-detangle hair without a heavy silicone feel.

Worth knowing
Because it is water-dispersible, it tends to rinse out more easily than many traditional silicones. It is commonly used in both rinse-off and leave-in formulas for added manageability.
