Bond repair treatments for bleached, colored, and heat-damaged hair. Olaplex, K18, and the masks and oils that rebuild structure rather than just coating it. Curated by Benvyre for anyone whose hair has been through a lightening session and now snaps...
The one that started the bond-repair category. It's a pre-shampoo treatment, not a conditioner that's the mistake most people make. Apply to damp hair, leave 10 minutes or longer, then shampoo out. Essential if you bleach.
Olaplex No.3 Hair Perfector + No.4 Shampoo Set
Finishing oil that doubles as heat protection to 450°F. Two or three drops, no more, or fine hair goes flat. The one product here that works on every hair type.
OLAPLEX N°.7 Bonding Hair Oil, Heat Protect
Four minutes, no rinse, and the results on badly damaged hair are the most dramatic of anything in this list. Use it on clean damp hair with nothing else layered underneath it needs direct contact. Expensive per use and worth it after bleach.
K18 Leave-In Molecular Repair Hair Mask
Clean formulation with rosehip and argan oil for people avoiding silicones and sulfates. Weekly, on damp hair, 10–20 minutes. Rich enough that fine hair should keep it to mid-lengths and ends.
Briogeo Don't Despair, Repair! Deep Mask
Bond-building mask with sea buckthorn, aimed at heat and colour damage. Sits between a weekly conditioner and a clinical treatment. Strong fragrance lovely to most people, worth knowing if you're sensitive.
amika the kure intense strength repair mask
Humidity-proofing rather than repair, and it genuinely works: spray on damp hair, blow-dry to activate, and the heat is what sets it. Skip the blow-dry and it does nothing. Lasts three or four washes.
COLOR WOW Dream Coat Anti-Humidity Spray
Lightweight finishing oil with hemi-squalane for shine without weight. Warm one or two drops between palms and press into ends only. Fine hair should use less than feels right.
