As it turns out, you may be missing out on one key product with major multitasking benefits — hair serum!

Packed with a potent concentration of key ingredients, hair serums can effectively smooth, soften, and protect the hair from environmental aggressors. This way, your hair stays sleek and shiny all day long.

Love the idea of a hair serum but aren’t sure how to work it into your haircare routine? Below, we’ve broken down all of the essential do’s and don’ts of using this all-in-one product so you can start making the most of your daily hair goals.

Not to be confused with hair oil, hair serum is a silicone-based styling product designed to coat the hair’s surface to help impart added shine, smoothness, hydration, and humidity and pollution protection.

Intended to be used on wet or dry hair, serums can act as both a pre-styling treatment and a finishing product. It’s perfect for wash days, in-between washes, on-the-go touch-ups, and stylist-free days.

While some serums get a bad rap for being too heavy and slick for fine, thin, or oily hair types, our specially engineered hair serum is 100% customizable. That means it’s suitable for a variety of hair types, from coarse hair to fine hair.

The deets: Function of Beauty’s hair serum is formulated with a mix of argan oil, jojoba oil, and sunflower oil. Besides that, it features a custom blend of synthetic and naturally derived ingredients, including vitamin E, depending on your favorite hair goals. Just like the other haircare products at Function of Beauty, our hair serum is paraben-free, sulfate-free, and doesn’t contain other unwanted ingredients. (Check out our “No” list because what’s in your products is just as important as what’s not in them.)

The key to getting the most out of your hair serum, however, is learning how to use it properly. That’s why we’ve put together some quick do’s and don’ts for you to follow below.
