DEVICE FOR THERMAL TREATMENT OF CHEMICALLY TREATED HEAR AND HAIR TREATMENT METHOD USING SUCH METHOD Russian patent published in 2014 - IPC A45D7/06 

FIELD: personal use articles.

SUBSTANCE: present invention relates to thermal hair treatment and to a hair treatment method using such treatment wherein heat energy has an effect on hair whereon cosmetic chemical means such as a colouring agent is applied during the hair perming, colouring or similar procedure. Thus, the present invention proposes the hair thermal treatment method by way of heat energy transmitting to the hair whereon cosmetic chemical means is applied thus to perform thermal treatment wherein heat energy from the electric heater is primarily transmitted to a metal item, the heat transmission coefficient whereof is equal to at least 150 kcal/(m²h°C); heat energy from the metal item is secondarily transmitted to a non-metal item, the heat transmission coefficient whereof is equal to nearly 0.20 kcal/(m²h°C) thus to perform heat transmission by way of contact of the said non-metal item and the hair.

EFFECT: invention proposes various methods for hair treatment by way of heat impact on the hair at a high temperature so that keratin, as the base hair component, is relaxed under the heat action; herewith the hair is swollen so that cosmetic chemical means may freely penetrate into the hair and be washed out from it.
