Treatment agent for permanent wave and permanent wave manner null

摘要

PURPOSE:To oxidize and fix hair with suppressing the decrease of elastic modulus by using a hydrogen peroxide solution having a specific range of pH and H2O2 concentration as a second agent, treating hairs wound on a rod with a keratin-reducing first agent and treating with said second agent. CONSTITUTION:The subject treating agent composed of a hydrogen peroxide solution having pH4.5-7.5 and =0.3wt.% (preferably 0.01-0.05wt.%) H2O2 concentration is prepared and hairs are wound on a rod, etc., then are treated with a permanent wave first agent of keratin-reducing property, thus washed in water and treated with the above-mentioned treating agent as a second agent to oxidize and fix the shaped hairs. Treatment with the second agent is preferably performed at 37-47 deg.C (more preferably 40-45 deg.C) for 2-15min. By using the above-mentioned treating agent as the second agent, decrease of elastic modulus owing to the permanent treatment is extremely smaller than conventional method and decreasing of resilience of the hairs is not perceptible.
