Sure, brow pencils and pomades are great for faking fuller brows. But when you're hoping to see some actual growth, you'll need a product that does more than add a tint of color. The truth is, there's no clinical evidence to prove that plant-derived oils can help with brow regrowth (though there is a lot of anecdotal evidence). But similar to how conditioner nourishes the hair on your head, the best oils for eyebrow growth can improve the appearance of your brows by making them stronger and shinier. For potential brow (and lash) growth, castor oil is the dermatologist-recommended oil to use, as it's naturally rich in moisturizing and circulation-stimulating fatty acids like ricinoleic acid. To maximize on the benefits and minimize the risk of irritation, look for formulas that are made of 100% cold-pressed castor oil (and even better if they’re USDA-certified organic).
While castor oil is your best bet if you want to stick with a single product to nourish your brow hairs, other pro-approved ingredients include biotin and peptides. Though there isn't any definitive data to prove biotin actually helps with hair growth, it is an essential vitamin for producing keratin, which is the protein that makes up your hair, skin, and nails. You can most commonly find these ingredients (and other moisturizing oils) in serums and treatments formulated specifically for your lashes and brows.
Additionally, you can ask your dermatologist about using one of the two medications that have been shown to improve hair growth: topical minoxidil, which is intended to be used on the scalp, and Latisse, which is available via prescription.
You should always do a patch test on your arm before putting any new product on your face, and if you're particularly sensitive (or just cautious), you can always speak with your dermatologist or ophthalmologist before using castor oil on your eyebrows. Always apply the castor oil to clean brows, and in order to increase the likelihood of seeing results, use it consistently (either at nighttime before bed or in the morning as part of your p.m. skin care routine).

Not having to deal with extra wands is definitely a plus.."
