According to the inventive method for permanently shaping hair, an alkalinely hydrolizable compound is added to an alkaline perming agent which contains a keratin-reducing active agent and which has an initial pH value of 7.5 to 10, immediately before use. The hair is then treated with the prepared agent before and/or after it has been fixed in the desired shape. At the end of the exposure time, the hair is rinsed with water, oxidatively re-treated, re-rinsed with water, optionally styled with curlers and then dried. The inventive method is characterised in that the alkalinely hydrolizable compound chosen is such that the initial pH-value is lowered by at least 0.5 units within 5 to 30 minutes without the addition of an ester-splitting enzyme. |
