Defined waves and curls need two things that are often in tension: enough hold to keep the pattern intact through the day, and enough moisture to keep the hair soft, moveable, and frizz-free rather than stiff and dehydrated. KMS CURLUP Wave Foam delivers both — a lightweight styling foam with a flexible hold system that enhances wave and curl formation, locks in definition for up to 72 hours in humidity, and incorporates moisturising properties specifically for waves and curls that go dry in hot summers or cold, dry winters.

CURLUP Wave Foam is built around KMS's Innovative Shaping Blend — a combination of professional hold polymers and botanical actives calibrated for wavy to curly hair that needs definition without rigidity.

VP/VA Copolymer is the primary hold resin — a flexible vinyl-based polymer that sets around wave and curl formations as the hair dries, holding the pattern in shape through movement and humidity. VP/VA Copolymer's flexibility is the key characteristic: it creates hold at a level of 2 out of 5 on KMS's scale, designed specifically for natural-looking waves and curls that move and bounce rather than stay frozen. The low hold number is not a limitation — it is the design intent for a wave foam whose primary goal is definition and frizz control, not structure.

Hydroxypropyltrimonium Hydrolyzed Corn Starch is a cationic starch derivative that provides a double function: body-building and moisture management. It deposits a lightweight, positively charged film on the hair shaft that adds body and definition to wave patterns, while its starch base absorbs excess oil and provides the micro-texture that helps curls and waves hold their shape through the day.

Propylene Glycol and Glycerin form the formula's moisturising core — two complementary humectants that draw moisture from the environment into the hair shaft and hold it there. This is the mechanism behind the "moisturising properties" highlighted by KMS: the humectant system actively maintains the hair's internal water content through the styling and drying process, preventing the dehydration that causes curls to become brittle, crunchy, or undefined. Panthenol (provitamin B5) reinforces this at a structural level, penetrating the cortex to bind moisture and improve the elasticity that allows waves and curls to spring back to their pattern.

Mentha Piperita (Peppermint) Leaf Extract and Citrus Aurantium Dulcis (Orange) Flower Extract are the botanical actives in the CURLUP Shaping Blend — providing a calming, curl-enhancing botanical contribution alongside their characteristic sensory properties. Peppermint is traditionally recognised for its stimulating and refreshing effect on the scalp; Orange Flower for its soothing and softening properties on sensitised hair. Acrylates/Palmeth-25 Acrylate Copolymer and PVP provide supplementary hold support and film-forming stability. Ethylhexyl Methoxycinnamate provides UV protection at the hair shaft level. Sorbitol adds additional humectant moisture retention.

The fragrance is a vibrant blend of fruits, flowers, and greenery with subtle sweetness and clear, harmonious vibrancy — the signature CURLUP scent profile.

Metro Vancouver note: Coastal humidity in Metro Vancouver supports the moisture balance that waves and curls need — but it also drives frizz expansion in hair that isn't properly conditioned or held. The 72-hour humidity resistance of CURLUP Wave Foam, combined with the Propylene Glycol and Glycerin moisturising system, keeps waves defined and frizz-free through the specific conditions of Vancouver's damp coastal climate rather than fighting against them.

Who It's For Wavy (2A–2C) to curly (3A–3C) hair of any density. Particularly effective for fine wavy hair that heavier curl creams weigh down, and for any curl type that experiences dryness in dry winter conditions or hot summer heat. Work through towel-dried hair before diffusing or air-drying — do not apply to soaking wet hair, which dilutes the formula and reduces wave definition.

Key Ingredients

• VP/VA Copolymer (Innovative Shaping Blend) — Flexible hold resin; sets around wave and curl patterns without rigidity for natural-looking definition with movement
• Hydroxypropyltrimonium Hydrolyzed Corn Starch — Cationic starch derivative; adds body and definition to wave patterns while absorbing excess oil
• Propylene Glycol & Glycerin — Dual humectant moisturising system; draws moisture into the hair shaft and maintains it through the drying process to prevent crunchy, dehydrated curls
• Panthenol (Provitamin B5) — Penetrates the cortex and binds moisture structurally; improves elasticity for curls and waves that spring back to their pattern
• Mentha Piperita (Peppermint) Leaf Extract — Botanical active; stimulating, refreshing, and curl-enhancing
• Citrus Aurantium Dulcis (Orange) Flower Extract — Botanical active; soothing and softening for sensitised hair
• Ethylhexyl Methoxycinnamate — UV filter; protects the hair shaft from photo-oxidative damage through the day

HOW TO USE: Work through towel-dried hair from roots to ends. Scrunch into lengths to encourage wave and curl formation. Diffuse with a diffuser attachment for enhanced definition and volume, or air-dry for a softer, more natural wave.

Stylist tip: Apply to towel-dried rather than soaking-wet hair for best definition. Excess water dilutes the hold polymer and reduces wave pattern formation. Scrunch out the cast once fully dry for soft, touchable waves.
