The frequency of using purple shampoo depends on your hair color, brassiness level, and hair type, but general guidelines are as follows:
- For blonde or silver hair aiming to maintain a cool, ashy tone, use purple shampoo about once a week. If brassiness is stubborn, you can increase to twice a week temporarily
- For brunettes with blonde highlights or balayage, use purple shampoo more sparingly, about once every two weeks or as needed to tone highlights without affecting the base color
- For gray hair, once a week is recommended, or less frequently if you wash your hair less often
- Purple shampoo should not be used daily unless the formula is specifically designed for daily use, as overuse can cause a purple or lavender tint and dryness
- If you notice purple buildup or tint, reduce frequency and use a clarifying shampoo to remove excess pigment
- Start with a small amount and adjust based on how your hair responds
In summary, most people benefit from using purple shampoo once or twice a week, adjusting based on hair needs and avoiding daily use to prevent unwanted color buildup or dryness
