H1 Straightener Except for the roots, coat the entire hair evenly, and let it set at room temperature for 10 to 20 minutes. Then, after sufficiently plain rinsing, dry the hair and set it with a special iron at 180.c/ 356.f or less for 2 seconds per location to straighten the hair. When applying H1 Straightener, keep it 1 to 2 cm above the roots, as getting it on the scalp could cause irritation and hair for breakage. Use an intermediate plain rinse to completely wash away H1 Straightener. Especially wash the roots carefully. 2 Neutralizer Coat the entire hair and leave it for 20 minutes while coming lightly. Then, completely wash it away. Completely process H2 Neutralizer. If the neutralization is not complete, it could cause damage or hair for breakage, so coat the hair sufficiently from the roots to the tip of the hair to make sure neutralization is complete.
