PURPOSE:To titled first solution that contains cysteamine or its derivative, thus showing improved wave-forming performance. CONSTITUTION:The first solution for permanent wave is obtained by adding 0.1- 15wt%, preferably 0.5-10wt%, of cysteamine, HSCH2CH2NH-R (R is methyl, ethyl, propyl, hydroxyethyl), or its derivative. Further, a known reducing agent such as thioglycolic acid, cystein, acidic sodium hyposulfite, sodium sulfite or thioglycerol is added to the above compound by 0.01-100pts.wt. per lpt. of the cysteamine to increase the wave-forming performance synergetically. |
