OUAI Thick & Full Supplements ($42 for 30-day supply; $36 for refill pouch)
A daily vegan supplement for thinning hair, each flavorless capsule boasts a potent blend of strengthening biotin, pea sprout extract for less shedding, and a Multivitamin Complex to support the overall health of every strand. You only need one capsule per day, and you can take it on an empty stomach, which is convenient if you’re always on the go.
“Scalp health is so important to the overall health of your hair,” says OUAI founder and celebrity hairstylist Jen Atkin, noting that results of the supplements can usually be seen in 60 days. “Think of your scalp as the soil in a garden—you need to tend to the soil for everything to grow. The Thick & Full Supplements are key to keeping hair follicles clear and healthy, which can help promote hair strength. By keeping the skin on your scalp hydrated and soothed from the inside out, you’re supporting an environment for healthy hair growth, stronger strands and less shedding.”
