1. Olaplex No. 3 Hair Perfector
This cult-favorite bond-building treatment repairs heat-damaged hair by re-linking broken disulfide bonds. Ideal for over-processed or bleached hair, it reduces breakage and improves elasticity. Apply to damp hair, leave for 10+ minutes, then rinse for visibly smoother strands. Works best with the Olaplex system (No. 4–8).
2. K18 Leave-In Molecular Repair Hair Mask
A peptide-infused mask that penetrates the hair cortex to undo heat and chemical damage. Unlike surface-level treatments, K18 rebuilds keratin chains for long-term repair. Use post-shampoo (skip conditioner) for 4 minutes—results improve with consistent use.
3. Redken Extreme Anti-Snap Leave-In Treatment
Heat-weakened hair snaps easily. Redken’s protein-rich formula reinforces strands with lipids and ceramides, reducing split ends by 53% (brand study). Spray on towel-dried hair before styling to shield against infrared heat.
4. Briogeo Don’t Despair, Repair! Deep Conditioning Mask
A vegan deep conditioner with rosehip oil and B vitamins to hydrate parched hair. Perfect for curly or coarse textures, it detangles while repairing. Leave on for 10–30 minutes weekly for restored shine.
5. Moroccanoil Restorative Hair Mask
Infused with argan oil and keratin, this mask smooths frizz and seals split ends. Ideal for high-heat users, it also adds UV protection. Apply to damp hair for 5–7 minutes.
6. Living Proof Restore Repair Mask
A science-backed treatment with OFPMA technology to strengthen hair fibers. Reduces breakage by 75% in one use (brand claim). Works for all hair types, especially fine hair.
7. Pureology Hydrate Superfood Treatment
A plant-powered mask with chia seeds and coconut oil to nourish heat-stressed hair. Sulfate-free and color-safe, it revives moisture without weighing hair down.
