If you're anything like me and obsessed with thick, fuller brows, then you may have noticed the influencer queen and former Love Islander Molly-Mae recently rave about her new eyebrow serum and how it has quite simply changed her life and, of course, her eyebrows. Whether you're a 90s baby who embraced the skinny brow trend a bit too much or just not blessed with fluffy brows, we've done the hard work for you and found the best eyebrow growth serums that actually work.
While it's so easy to be overzealous with the tweezers (guilty as charged), your eyebrow hairs are very delicate, and if over-plucked, they can take a long period of time to grow back to the way you would like them. A lesson I once learnt from my auntie/beautician after her trying to salvage my teenage over-plucked brows was don't fix something that isn't broken.

Everything you need to know about eyebrow growth serums:
How do eyebrow growth serums work?
Eyebrow growth serums are all about nourishing your existing eyebrow hair right at the follicle, encouraging your eyebrow hair to grow strong and long over a set period of time when used consistently. It's important that your eyebrow growth serum includes lots of nourishing ingredients, such as peptides, as these will help to kickstart growth in any of those sparse areas where over-plucking may have occurred. Conditioning extracts such as castor oil and panthenol are also components to look out for, as these will help to keep the hair hydrated and happy, which in turn will lead to glossier, fuller brows.
How often should you use eyebrow growth serum?
Each eyebrow growth serum will have different usage guidance, so it's important to read the brand's instructions. While most eyebrow growth serums will only require you to brush the formula through once a day, more specific/high-intensity eyebrow serums may need you to do it twice a day. The best thing to do is always keep it by the side of your bed, so you apply it every evening or in your everyday handbag if you need to do it more than once a day.
How long does it take for eyebrow growth serums to work?
While you would hope the results are somewhat immediate, most eyebrow growth serums take time and patience. If you buy a serum that includes growth-inducing ingredients like minoxidil, you'll potentially see hair growth within six to eight weeks when brushed on daily. However, if ingredients are more about conditioning the hair (think hyaluronic acid, peptides, aloe, amino acids), then you'll probably see some growth and thickness over the course of a couple of months if used daily.
