Function of Beauty launches a $25 customized hair serum

Everyone’s got their own bad hair issues. Mine is a packaged deal of frizz, dryness and split ends. But whether you’re looking for a solution for colour protection, frizz control, an oily scalp — or heck, all of the above — Function of Beauty may just have the serum you’ve been looking for.

The custom hair care authority launched their first-ever Hair Serum. Just like their Insta-famous, dreamy-hued shampoo and conditioner, which have nearly 27,000 five-star reviews, this new serum is completely customizable. Their latest product allows you to select up to five added hair goals and a fragrance in order to create your own unique formulation.

How? Function of Beauty’s easy to use website offers a short quiz to narrow down your biggest hair concerns and needs upon ordering. Thanks to a team of world-class engineers and data scientists, the algorithm of quiz results pull hundreds of ingredients to potentially create billions of one-of-a-kind serums to achieve that “glass hair” look.

Each serum is created to fit custom hair needs, all are based with four key ingredients which are proven to smooth frizz and flyaways while increasing your hair’s overall manageability: argan oil to promote overall hair health, annatto oil to protect hair from damage, jojoba oil to nourish and smooth hair cuticles and sunflower oil to instantly add weightless shine.

“I don’t usually use hair serum because it’s very oily on my hair — this product, however, was not [oily] at all. It went on smooth and soaked in right away, not leaving any oil behind,” said one reviewer who received the product as a part of a testing group.

For the best results, warm a small about of product in your hands and then apply to dry or damp hair. Evenly run the product through the mid-shaft to ends of your hair, avoiding the scalp and the roots.
