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

This styling liquid is formulated to give limp, fine hair visibly fuller texture without weighing it down. Designed for use on clean, damp hair, it layers easily with other products and dries to a natural, touchable finish. A luscious berry fragrance blends red raspberry, strawberry puree and tropical fruit to leave hair smelling fresh while UV protectants help guard against sun-related fading and damage.

How will this styling liquid change my fine hair morning routine?

Apply a small amount to towel-dried hair and distribute from roots to ends to create lift at the scalp and fullness through the lengths. It works quickly with blow-drying or air-drying and won’t leave stiff, crunchy residue, so styling stays flexible throughout the day.

• Use a nickel-to-quarter sized amount depending on hair length.
• Concentrate at roots for lift, smooth through ends for shine.
• Works with heat tools for enhanced body or lets hair air-dry naturally.

What kind of finish and hold can I expect from Paul Mitchell Thicken Up?

The formula provides light-to-medium control with a soft, natural finish—adding texture and separation without a heavy feel. Hair looks thicker and bounces with movement rather than appearing stiff or sticky.

• Soft, touchable hold that preserves movement.
• Enhances definition and separation for layered styles.
• Adds shine while maintaining a natural-looking finish.

Does this product protect hair from environmental stress like sun exposure?

Yes—Thicken Up includes UV protection to help reduce the effects of sun exposure on color and strand integrity. While not a substitute for full sun protection practices, it contributes to daily defense against UV-related fading and dryness.

• Built-in UV filters for everyday protection.
• Helps prevent premature color fade from sun exposure.
• Supports smoother, less brittle-looking strands under sunlight.

How should I combine this styling liquid with other products?

The lightweight texture makes it an ideal layering product: use it before heavier creams or oils, or pair it with a texturizing spray for extra volume. It complements conditioning treatments—apply Thicken Up after leave-in conditioners and before finishing serums.

• Apply on damp hair, then follow with mousse or volumizing sprays if needed.
• Layer under lightweight oils or shine serums, avoiding excess at the roots.
• Safe to use with heat protectants and color-care routines.

Who is this for? Paul Mitchell Extra-Body Thicken Up Styling Liquid is designed for people with fine or limp hair who want noticeable volume without stiffness. It’s suited to anyone seeking an everyday lightweight volumizer that offers softness, shine and a pleasant berry scent, while supporting color and hair health with UV protection. Ideal for salon clients or everyday users looking to add body and manageability to thin strands.
