The one product your hair needs this summer

If there’s one product your hair needs to weather summer beautifully, it’s an oil—but these hydrating, reparative products are far from one size fits all. Use too-heavy of a product on thin hair and you’re left with flat, greasy mess—and a too-light product will be sucked up by dry, damaged strands in a flash. The solution: Prose Hair Oil, a totally customizable hair oil you can tailor to your skin’s needs.

You get your name on your custom formula!

This once-limited-edition multitasker is now a permanent part of the Prose line—probably because it was such a hit the first time around—and all you have to do it take a simple quiz about your hair including age, natural hair texture, length, condition (oily, dry, etc.), thickness, density, usual time between washing, scalp sensitivity, where you live and more. You also get the option to create a vegan, gluten-free and/or silicone-free formula as well. Lastly, you select from three scents, including floral, fruity and fresh options (or no scent at all), and whether you want your hair to have more volume, shine, curl or smoothness. Your answers guide you to the ideal oils and other ingredients, and here’s a screenshot of my bespoke formula.

Even more, you can use your personalized oil in a number of ways. Use it as a treatment on dry hair (I love doing this when I just hanging out around the house) before you know you’ll be washing. It also works as a styling product to help minimize frizz, and it can be used as a touch-up between washings to smooth flyaways, moisturize and add shine.

And you get all this in one bottle that has YOUR name on it. If you only do one thing to treat your tresses this summer, this customized oil should be it.
