Match serum to your primary concern

Choose formulas targeted for frizz control, heat protection, repair, or faster drying depending on whether you need smoothing, styling under heat, split-end repair, or quicker blowouts

Check for heat-protection claims

If you frequently use blow dryers or flat irons, prioritize serums that explicitly provide heat protection to reduce breakage and thermal damage
