HOW IT WORKS

Sun exposure fades colour, strips shine, and breaks down the proteins that keep hair strong. KERARICE™ counters this with four rice-derived components: an antioxidant that neutralises UV damage, amino acids that strengthen each strand, peptides that repair and smooth from within, and polysaccharides that protect the hair surface with continued use. 5

KEY BENEFITS

Protects Hair Color: Prevents fading of natural and artificially dyed hair caused by UV radiation and sun exposure, including in bleached and highlighted hair types. 1,3,5
Recovers Hair Brightness and Shine: Restores luminosity to dull, UV-damaged, or chemically treated hair. 1,3,5
Strengthens the Hair Fiber: Improves hair's resistance to breakage and physical stress for stronger, more resilient strands. 1,3,5
Protects Hair Keratin and Lipids: Shields the natural building blocks of each hair strand from UV damage to maintain strength and condition. 1,3,5

INTERACTION WARNINGS

Kerarice is well tolerated at normal use levels and confirmed non-irritating in patch testing. 6 As a general reminder, avoid combining Cellexia products with retinol. Discontinue use if any scalp irritation occurs.

Rice Extract Protects Hair from UV Damage: A rice-derived extract containing peptides, polysaccharides, and phytic acid was shown to reduce UV-induced lipid damage, protect hair shine and colour, and improve mechanical strength, with phytic acid identified as the key antioxidant responsible. 8
Rice Bran Extract Supports Hair Follicle Activity: Rice bran extract containing phytic acid and other bioactive compounds was shown to modulate gene activity related to the hair growth cycle and reduce inflammation in hair follicle cells, supporting the broader hair-active potential of rice-derived ingredients. 9
Rice-Derived Compounds Support Hair Growth: Rice bran extracts containing phytic acid and related compounds significantly boosted hair follicle cell growth, outperforming well-known hair loss treatments on key growth markers, supporting the hair-active potential of phytic acid and rice-derived actives. 10
