Buying Guide: Key Purchase Considerations
- Hair type and needs: Choose a serum formulated for your hair texture (straight, curly, fine or thick) and problems (severe frizz, colour-treated, or bond repair).
- Primary benefit: Decide between hydration, frizz control, heat protection, bond repair, or shine enhancement to match your goals.
- Active ingredients: Keratin and proteins offer strength; argan, avocado, and other oils provide moisture; bond-repair complexes help rebuild internal hair structure.
- Application and weight: Lightweight serums suit fine or oily hair; richer formulas suit dry or damaged hair but may weigh down lighter textures.
- Heat protection: If you frequently use heat styling, prioritise serums with a thermal shield to reduce breakage.
- Allergen and sensitivity considerations: Look for paraben-free or fragrance-free options if you have sensitive scalps.
- Routine compatibility: Consider whether the serum is leave-in for convenient daily use or rinse-out for deeper treatments.
- Ethical aspects: Cruelty-free formulations may align with personal or ethical preferences.
- Maintenance: Regular use over weeks often yields best results; avoid layering too many heavy products at once unless advised.
