That said, you might be looking for some low-lift ways to sport strong, healthy brows—so you don’t have to spend considerable time in the mirror, brow pencil in hand. Which raises the question: Can taking collagen help? We know the supplement has some pretty promising benefits for hair health (read up on the highlights here). But can it do the same for brows? Here’s what we know. So while it can’t necessarily revive those severely damaged follicles, Yates says it absolutely can support the growth phase for your brows, just like it does for the hair on your head. Here’s how it works: Your hair (brow hairs, too!) is mainly made up of the protein keratin1. For the body to build that keratin, it needs several types of amino acids, many of which are part of collagen peptides2. The theory follows that if you ingest these amino acids, they can help support your natural levels of these essential ingredients.* And while there are plenty of collagen-rich brow products meant to coat those hairs and help them thicken, topicals can only get you so far. According to Yates, “to see any positive effects, you must take [collagen] internally versus topically.” It doesn’t stop there: Adding grass-fed collagen+ to your coffee can also enhance the arches you already have. That’s because the powder contains vitamin C and vitamin E, known for its antioxidant properties and managing oxidative stress. Like the strands on your head, your brow hairs are vulnerable to free radicals, so you’ll want to tend to the area with antioxidants, which includes covering the brows with an antioxidant serum, yes, but ingesting those ingredients can help your body enhance its natural protection process as well.* As brow expert Joey Healy notes, “It’s best to use collagen supplements and a brow serum to have a two-way approach.”
