A process for setting hair which comprises the steps of subjecting at least partially dry hair wound on a tubular member to the action of steam at a temperature between 110.degree. and 150.degree. C. for a period of 1 to 60 seconds, without substantially otherwise heating the hair, and unwinding the hair from the member only after the hair is cooled to about ambient temperature.
Process for treating the hair which comprises the step of injecting steam at 110.degree. to about 150.degree. C. into the hair, to add moisture to the hair without wetting the hair and in which said steam contains gaseous chemical compositions adapted to modify the properties of the hair.
Process of treating the hair in which steam at 110.degree. to about 150.degree. C. is introduced into hair to add moisture to the hair without wetting the hair which has been first impregnated with a chemical solution or is wound on rollers which have been impregnated with a chemical solution.
