💡 The Golden Rule: Once a Week
The general consensus among hair care experts is that once a week is the sweet spot for most people. This allows the violet pigments to neutralize yellow or brassy undertones effectively without leaving your hair looking ashy or purple.
However, this isn’t a one-size-fits-all rule. It depends heavily on your specific hair type and how quickly your strands absorb color.
🌟 For Light & Silver Hair
If you have very light blonde, silver, or gray hair, you might need to use it more frequently—up to twice a week. These tones are more prone to developing brassiness quickly, and the pigment doesn’t last as long on lighter strands.🌿 For Darker or Thicker Hair
For darker blondes or thicker hair types, once every other week may be sufficient. Overuse can lead to an unintended violet tint, so it’s important to monitor your hair’s response.⚖️ Balancing the Scale: Pros & Cons of Frequency
Finding the right balance is key to maintaining healthy, vibrant hair.
Pros
- Neutralizes Brassiness: Regular use keeps unwanted yellow tones at bay.
- Maintains Vibrancy: Helps preserve the freshness of dyed or highlighted hair.
- Professional Results: Salon-standard maintenance at home.
Cons
- Dryness Risk: Purple shampoos can strip natural oils; using them too often without a conditioner can make hair brittle.
- Ashy Cast: Over-depositing purple pigment can make hair look dull or grayish instead of shiny.
✅ Best Practices Checklist
To get the best results without damaging your locks, follow this routine:
Start Slow:
- If you are new to purple shampoo, begin with once a week to see how your hair reacts.
- Monitor Response: Check your reflection after rinsing. If you notice a faint purple tint, reduce frequency next time.
- Pair with Conditioner: Always follow up with a hydrating conditioner or a purple conditioner to seal the cuticle and add moisture.
- Limit Duration: Leave it on for 3-5 minutes max. Longer than 10 minutes increases the risk of over-toning
