**Question:** Which hair oil is good for fine hair?

**Short answer:** Olaplex No.7 Bonding Hair Oil has the best record for fine hair: 19 of 19 shoppers said it kept their hair light, not greasy or flat. This page counts shoppers who said they have fine or thin hair, and no one else. Paul Mitchell Super Skinny Serum is also unbeaten (10 of 10) but from a small group, and OUAI Hair Oil follows at 17 of 18. Verb Ghost Weightless Hair Oil has the weakest record here at 21 of 24, and just 4 oils had enough counted reviews to be ranked.

**What stands out:** Weight is what can go wrong on fine hair: 3 of 24 shoppers said Verb Ghost Weightless Hair Oil left their hair greasy, flat or weighed down. OUAI draws price complaints, at 18% of its reviews.
