Genesis Défense Thermique Blow Dry Primer ($45)
If you heat style your hair, a heat-protectant spray is a non-negotiable. This product doesn’t just coat hair in a figurative protective bubble though—it treats “hair fall,” aka damage and breakage from brushing and styling. Use it on damp hair before styling for a 24-hour healthy, frizz-free style.
Size: 5.1 oz | Key ingredients: ginger root extract, edelweiss native cells, arginine | Best for: all hair types and hair weakened from styling
