Abstract
A permanent hair setting apparatus is disclosed wherein infrared radiation is used to heat the hair in conjunction with a permanent setting composition to a temperature of 100.degree. C. Heating of the hair occurs by winding the hair on infrared generating formers. The apparatus allows for the attainment of permanent setting with a heating time of only 5-60 seconds. Relatively dilute solutions of permanent setting composition are required, which dispenses with the need to neutralize the hair after setting. The use of the apparatus thereby permits permanent setting of the hair to be completed within about 30 minutes.
Claims14
A permanent hair setting apparatus comprising:
- i) a hollow infrared radiation transparent hair former adapted to have hair wound thereon;
- ii) an infrared radiation source comprising a hot wire within the hair former, the hot wire being capable of being heated continuously up to a temperature of 1100.degree. C. using a voltage in the range of from 4 to 30 volts;
- iii) means to cover the hair wound on the hair former to an extent sufficient to maintain the hair moist during the time in which the infrared source is activated, the means comprising a water impermeable member of sufficient size and shape to substantially cover all the hair being set on the hair former;
- and
- iv) a water absorbent member in contact with the means to cover the hair and disposed such that it is between the means and the hair former, but spaced apart from, the hair former by a distance sufficient to allow hair to be wound onto the hair former.
