Buying Guide: Key Purchase Considerations

• Hair color level and tone: Choose a product that targets your specific shade (brunette, blonde, platinum) and the intensity of brassiness.
• Shade of toning pigment: Blue-violet tones neutralize brassy orange hues; purple-toning formulas are a common alternative for blondes.
• Color-treated vs. natural hair: Some formulas are designed to be gentler, while others deposit stronger pigments—balance pigment strength with hair health.
• Hydration and sulfates: Hydrating, sulfate-free options help prevent further drying, especially for color-treated hair.
• Additional benefits: Look for UV protection, strengthening ingredients, or conditioning that supports overall hair health.
• Usage frequency: Some products are recommended for weekly use; others can be integrated into regular routines as needed.
• Allergen and strand testing: For color-sensitive or sensitive scalps, perform a strand test and check ingredient lists for potential irritants.
• Pairing with conditioner: Many sets include a conditioner to lock in cool tones and maintain moisture; consider pairing recommendations for best results.
• Maintenance schedule: Consistency matters; over-toning can lead to overly cool or dull tones, so adjust frequency based on results.
• Brand compatibility: If you already use a particular brand’s system, you may benefit from continuity in formula and scent.
