About this ingredient
Dimethiconol is a silicone polymer with hydroxyl groups at chain ends. Differs from regular dimethicone (Dimethicone) by having reactive -OH groups, which let the molecule form hydrogen bonds with stratum corneum proteins. Mechanism. On skin it forms a thin breathable film, retains moisture in the stratum corneum, restores the barrier. On hair – seals the cuticle, smooths the surface, adds shine, protects against heat (blow-dryer, flat iron). Compared with regular dimethicone, dimethiconol adheres better to skin and hair after the first wash. Where applied. Shampoos, conditioners, hair masks, heat protection, 'glow' creams and serums. In Spain – Pantene Pro-V Repair, Garnier Fructis Daring Curls, Klorane Mango Repair, in L'Oréal Elvive serums. Evidence base. A functional component with many years of use in hair products. Effect on hair smoothness and heat protection confirmed in standard tests. On skin – sensory and film-forming properties confirmed; no active skin pharmacology. Safety. CIR confirmed dimethiconol safe in cosmetic use. Hypoallergenic, non-comedogenic, non-irritating. Suitable for fungal acne patients. Pregnancy and lactation – safe. No restrictions. Best suited to: dry, damaged hair, compromised barrier skin, post-procedure care. Any skin and hair type as a functional component.
