How much should I use?

Start with one or two drops warmed between the palms and work through mid-lengths and ends. Add more only if hair still looks dry.

Can I use it on wet hair?

Yes. Apply it to damp hair before blow-drying for heat protection and easier styling, or to dry hair to finish.

Use it sparingly and keep it off the roots. Fine hair can look weighed down if you apply too much.

Kérastase lists heat protection among its benefits, so it can be used before blow-drying or flat-ironing.

The travel size is a low-commitment way to try the oil before buying a full bottle.

Yes. It is a finishing oil for smoothing and shine and can be used on color-treated hair.
