Buying Guide: Key Purchase Considerations And Comparisons

Purpose and coverage: Decide whether you prioritise 100% grey coverage, vibrancy, or subtle enhancement. For extensive grey roots, a formula marketed for full grey coverage is advisable.

Formula and care: Ammonia-free or low-odor options can be gentler on the scalp, but may differ in processing time and scent. Look for nourishing ingredients such as conditioning oils or Pro-Keratin to support hair health post-colour.

Durability and fade: Permanent dyes typically offer longer-lasting colour, but fade rate depends on sun exposure, washing frequency, and your hair’s porosity. Consider shade choices that flatter your natural undertone and lifestyle.

Application method: Foams, oils, or oil-in-cream formulas affect ease of use and evenness of coverage. Non-drip foams can reduce mess, while oil-based formulas may enhance shine but require careful timing.

Maintenance: Aftercare products like colour-enhancing shampoos or masks help preserve brightness and mitigate dryness. A conditioning regimen improves overall hair health between sessions.

Safety and patch testing: Always perform a patch test at least 48 hours before use, especially if you have sensitive skin or a history of reactions to hair dyes.

Shade selection: Warm browns and caramel tones typically suit many UK complexions, but always consider your natural undertone. For darker hair, aim for shades labeled as 4 or 5 or consult guidance on how to achieve the closest match.
