Buying Guide: Key Purchase Considerations
- Hair type and damage: If your hair is highly processed or dry, choose formulations with added conditioning ingredients to avoid over-drying. Bond-building options can help alongside toning.
- Tone goals: Purple shampoos target yellow/brass tones, while blue-toning formulas are stronger for orange undertones. Consider your base colour and desired coolness when selecting a formula.
- Colour maintenance routine: Some products are designed for weekly use; others are gentle enough for more frequent use. Balance toning with a hydrating conditioner tailored to your hair needs.
- Ingredients and sensitivities: Look for vegan, silicone-free, or SLS/SLES-free options if you have sensitivities or prefer a more natural formula. AlgaPur and similar actives can offer additional strength.
- Brand compatibility: If you already use a bonded or strengthening system (like OLAPLEX), pairing with its purple-toning counterpart can maximise benefits without compromising bond integrity.
- Shade longevity: Regular maintenance, lightening level, and washing frequency influence how long the cool tone lasts. Use color-safe conditioners to extend results between washes.
