Experts Reveal How To Get Thicker, Fuller Brows, Plus Exactly Which Products To Use

Elite Daily/Amazon

Eyebrow serums have lots of purported benefits, and while they can help promote a thicker, fuller appearance, it's important to note that they won't actually grow back new hair, board-certified dermatologist Dr. Craig Ziering explains to Bustle. These over-the-counter products use peptides, emollients, humectants, thickeners, conditioners, and occlusive agents to repair the appearance of dry, brittle brows, but when shopping for the best eyebrow growth serums in particular, Look for formulas that contain things like hyaluronic acid, amino acids, and vitamins and minerals (such as biotin and panthenol).

Azi Sacks, an NYC-based eyebrow expert, says that using these serums consistently is key. Otherwise, when you stop, your brow hairs can shed and return to their original state. To further support brow growth, she advises keeping your brows moisturized using natural emollients and plant-derived oils (such as castor oil, almond oil, and coconut oil). It's also wise to stick with gentle cleansers and moisturizers, because the other products you use near your brows can absolutely affect their appearance, too. "Don't underestimate how delicate this area is. Give it lots of love!" Sacks says.

Finally, if you're experiencing more severe hair loss, Dr. Ziering suggests speaking with your dermatologist to discuss everything from lifestyle changes to prescription treatments to transplantation options.

With those tips in mind, scroll on to shop some of the best eyebrow serums (and other brow-boosting products) on the market right now.
