Hair extensions rely on conditioner more than your natural hair does — they don't receive oils from your scalp, so without regular conditioning they gradually dry out and tangle. The golden rule: apply from mid-lengths to ends only, keeping product well away from the bonds, rings or tapes, as conditioner at the root is the most common cause of extensions slipping.
Every conditioner here is chosen for extension wearers, from lightweight daily formulas to deep-repair treatments by Olaplex, K18, Kérastase, Moroccanoil and milk_shake. Condition every wash, and add a weekly hair mask to keep your 100% human hair extensions soft and glossy for their full 9–12 month lifespan.
