How do I use ONNI shampoo correctly?
Like many professional hairdressers, we recommend double shampooing for optimum cleansing:
- First wash: Use a small dab (about the size of a penny) to remove residue and styling residue. Emulsify briefly and rinse.
- Second wash: Depending on the length of your hair, apply a walnut-sized amount to the hair and shampoo the scalp and lengths thoroughly. Then rinse thoroughly.
A single wash is also possible.
