Two or three drops is the whole dose, and that is the first thing we noticed about Olaplex No.7. The oil is thin, almost serum-like, so it slides through dry ends without leaving the heavy film that makes fine hair collapse. We kept it away from the roots and focused on the last few inches, where dryness shows first.
What earns it the top spot is the combination of polish and protection. It adds shine and softness, tames frizz and flyaways, and carries a 450ºF/232ºC heat-protection claim, so it works before blow-drying or flat-ironing as well as after. The formula uses a coconut-derived emollient, vitamin E, and sunflower seed oil, and it feels weightless enough for every hair type in the line.
It is a finishing oil, not a deep pre-wash treatment. If your scalp is the dry part, a scalp oil or castor treatment is the better tool; this one is for the hair you see and touch. The dose stays small, so the bottle lasts longer than its size suggests.
We reach for it when we want the ends to look healthy without looking wet. That is a narrow job, and it does it neatly.
Bottom line: For most dry hair, this is the oil we send readers to first: a few drops add shine, softness, and heat protection without weight.
