Buying Guide
- Hair type and damage level: For very dry or chemically treated hair, prioritise rich hydration and bond-repair formulations. For normal to moderately damaged hair, lighter serums or sprays may suffice.
- Heat protection: If you frequently use straighteners or curling tools, opt for products that explicitly include heat protection to minimize further end damage.
- Bond repair vs. surface smoothing: Bond-repairing formulas target internal structural damage, while smoothing serums reduce frizz and improve finish. For best results, consider a two-step approach or a multi-benefit product.
- Texture and finish: Lightweight serums leave less residue and are suitable for fine hair, whereas cream-based treatments offer deeper conditioning for thick or very damaged hair.
- Application and usage: Leave-in formulas are convenient but ensure proper cleansing to avoid product buildup. Some products leverage heat to activate repair; use them as directed to maximise benefits.
- Allergen and scent considerations: Check for fragrance or additives if you have sensitive skin or a sensitive scalp.
