1. Select the lotion: Assess the hair type beforehand to determine which is the most suitable type of reducing liquid. In case of doubt, choose the gentlest. 2. Preparation: Wash with shampoo and dry with a towel, removing excess wetness. Choose the right size of curlers to create the desired wave or curl. 3. Applying the perm liquid: Use suitable gloves. Put in the curlers without rolling up too much paper. Pour the liquid into a non-metallic bowl and apply to the curlers. Use at least 80 ml for all the hair. Make sure the curlers are impregnated with the product. 4. Exposure time: Strength 1 = 15 minutes, strength 2 & 3 = 10 minutes. Do not use heat. Put on the hat, covering the whole head. 5. Fixing: Thoroughly rinse out the reducing liquid and remove excess water. Leave to work for 10 minutes and unroll the curlers one by one. Gently massage the hair from roots to tips. Rinse with plenty of water for at least 5 minutes.
