The Ultimate Guide to Using Purple Shampoo for Blonde Hair

The Ultimate Guide to Using Purple Shampoo for Blonde Hair

Ever wondered why your blonde starts looking dull or brassy after a few weeks? It’s not your colourist — it’s just tone fade and mineral buildup. Purple shampoo is your secret weapon for keeping blonde, balayage, or highlighted hair cool, bright, and salon-fresh between appointments.

At Di Moda Hair Studio, our go-to is Redken Color Extend Blondage — a professional-strength purple shampoo that neutralises yellow tones while reinforcing the hair’s internal bonds for stronger, brighter results.

How to Use Purple Shampoo

Start with wet hair, then apply a small amount of purple shampoo evenly through your mid-lengths and ends (avoid your scalp if it’s sensitive). Lather and leave for 1–3 minutes for gentle toning or up to 5 minutes for stronger brass control. Rinse thoroughly, then follow with Redken Blondage Conditioner or a hydrating treatment.

Pro tip: Always wear gloves — purple pigment can temporarily stain hands or nails.

How Often to Use It

Less is more! Most blondes only need purple shampoo once a week or every 2–3 washes. Overuse can leave a dull or violet cast. Alternate with a nourishing or bond-building range such as Redken Acidic Bonding Concentrate or Matrix Food for Soft to keep hair strong, hydrated, and glossy.

When to Start & When to Pause

  • After Colour: Wait about 1–2 weeks after your salon appointment before introducing purple shampoo. This allows your toner to settle and ensures long-lasting results.
  • Before Your Next Colour: Stop using purple shampoo about one week before your next appointment to prevent pigment build-up that can affect your toner’s clarity.

During your next visit, ask Maree to add a Metal Detox Treatment before your lightening service. It neutralises metals from water and colour buildup, helping your blonde last longer and feel smoother.

A great blonde isn’t just about your salon visit — it’s the care you give it at home. Using the right mix of purple, bonding, and moisture products keeps your blonde bright, soft, and healthy all year round.
