The recommended frequency for using purple shampoo varies depending on your hair type, color, and brassiness level:
- For blonde or silver hair aiming to maintain a cool, ashy tone, using purple shampoo once a week is generally effective. If stubborn brassiness persists, 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 too much
- Some purple shampoos are gentle enough to be used daily until you reach your desired tone, but if you notice a purple tint developing, reduce usage to a few times per week
- Overuse of purple shampoo can cause a purple or lavender tint and dull your hair color. To avoid this, limit use to once or twice a week and follow product instructions carefully
- If you accidentally leave purple shampoo on too long or use it too often, a clarifying shampoo can help remove excess pigment
In summary, start with once a week and adjust based on your hair's response and brassiness level, avoiding daily use unless the product specifically recommends it. Always follow the instructions on your specific purple shampoo for best results. Conditioning afterward is also advised to counteract any dryness caused by the shampoo
