What It Is

A lightweight body-building styling liquid that makes thin strands look and feel thicker — adding definition, softness, and shine to fine hair with UV protection and no heavy product feel. Vegan, gluten-free, and paraben-free.

Hair Concerns

  • Fine Hair & Volume
  • Shine & Gloss
  • UV & Environmental Damage
  • Frizz

Key Benefits

  • Methacryloyl Ethyl Betaine/Acrylates Copolymer is the primary volume-building polymer — deposits a lightweight film on each strand to make thin hair look and feel visibly thicker and fuller without heaviness or crunch.
  • Panthenol (Pro-Vitamin B5) and Polyquaternium-10 condition and smooth fine hair through the styling process — adding softness, manageability, and shine without the weight that would flatten fine strands.
  • UV protection (Cinnamidopropyltrimonium Chloride) shields hair from damaging UV rays — protecting both colour vibrancy and the integrity of fine, fragile hair against environmental stress.
  • PEG/PPG-14/4 Dimethicone and Dimethicone PEG-8 Meadowfoamate provide a lightweight conditioning layer and slip for easy styling — delivering the smooth, shiny finish without the silicone weight that would compromise volume on fine hair.

Highlighted Ingredients

Methacryloyl Ethyl Betaine/Acrylates Copolymer: Primary volume-building film-forming polymer; deposits a lightweight, flexible hold layer on each strand to physically thicken the appearance of fine hair

Panthenol (Pro-Vitamin B5): Penetrates the hair shaft to condition, add slip, and build gentle body without weight

Polyquaternium-10: Cationic conditioning polymer that smooths the cuticle, reduces static, and improves manageability through the styling step

Cinnamidopropyltrimonium Chloride: UV-absorbing ingredient providing protection against UV ray damage — shields colour and hair integrity during outdoor exposure

PEG/PPG-14/4 Dimethicone + Dimethicone PEG-8 Meadowfoamate: Lightweight silicone-based conditioning agents delivering the smooth, shiny finish and slip without adding weight to fine strands

Hydroxyethylcellulose: Natural cellulose-derived thickener that contributes to the formula's lightweight body-building texture and even distribution through hair

Vegan Gluten-free Paraben-free Colour-safe UV protection PCR packaging (post-consumer recycled materials)

What Else You Need to Know

Thicken Up works best on clean, damp hair before blow-drying — the heat activates the volume-building polymer for the best fullness result. Use a round brush and lift at the roots while blow-drying for maximum body. Can also be used sparingly on dry hair for a light hold refresh. Pairs with Paul Mitchell Extra-Body Shampoo and Conditioner for a complete fine hair volume routine. In Metro Vancouver's coastal humidity, fine hair tends to go flat quickly — the hold polymer in Thicken Up provides a structural layer that resists humidity better than product-free styling.

Fragrance

A luscious berry blend — red raspberry, strawberry puree, and tropical fruit. Fresh, sweet, and bright.

How to Use

Apply a small amount to clean, damp hair. Work through from roots to ends and style as desired. For maximum volume, blow-dry using a round brush, lifting at the roots as you dry. Can also be used sparingly on dry hair for a light hold refresh.
