The problem? Things can get goopy and greasy, fast. Ever go to apply your oil du jour and end up with a chunk of hair that’s noticeably denser and slicker than the rest? Or you try to work a bit of it through your strands, and your roots suddenly looked weighed down? “When using hair oils, I always recommend using a small amount at a time and working it all throughout your hands before applying it to the ends,” says Sal Misseri, owner of Reverie Salon, “then working upward, leaving hair closest to the scalp until last with just the leftover oil from your hands.” Complete and repeat this process section by section. Now, the size of the sections that you apply the oil to will vary: Those with fine, thin hair will likely be able to take more strands than someone with thick, full hair. And if you have questions about the amount of oil-to-hair ratio, err on the side of caution: It’s so much easier to add more later than it is trying to deal with a glob of over-oiled hair. Yes, this means a more diligent and time-consuming application process, but it will mean that the whole of your head looks shiny and healthy. Oh, and if you’ve ever noticed you can get away with applying more on out-of-the-shower strands than dry, you’re absolutely correct: “You can also use more hair oil on wet hair, and a quarter or less on dry hair,” he says.
