The recommended frequency for using purple shampoo varies depending on your hair type, color, and brassiness level, but general guidelines are as follows:
- For blonde or silver hair aiming to maintain a cool, ashy tone, using purple shampoo once a week is typically effective. If brassiness is stubborn, you can increase usage temporarily to twice a week
- 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
- If you have multi-colored hair but occasionally notice warm tones, use purple shampoo as needed, but avoid overuse to prevent a lavender tint
- Some purple shampoos are gentle enough for daily use until the desired tone is reached, but overuse can cause a purple hue, especially on very light or damaged hair. In this case, reduce usage to a few times a week
- Generally, purple shampoo should not replace your regular shampoo but be used up to twice a week, especially if you wash your hair twice weekly. This keeps hair bright without turning it darker or overly purple
- If you overuse purple shampoo, it can leave a purple, blue, or pink tint and may dry out hair, so always follow with a good conditioner or a purple conditioner to restore moisture
- Always follow the specific product instructions regarding how long to leave the shampoo on your hair, typically 2-5 minutes, to avoid over-toning
In summary, start with once a week and adjust based on how your hair responds, increasing to twice a week if needed but avoiding daily use unless the product is designed for it. Use conditioner afterward to maintain hair health. If you notice unwanted purple tones, reduce frequency or switch to regular shampoo for a few washes
