Achieve Fuller, Thicker Brows With These Expert-Approved Buys

"Castor oil is used in a list of beauty products, but using it alone is great for brow growth. It does wonders for the skin because it is a follicle-stimulating oil — full of vitamins, minerals, and ricinoleic acid. I recommend testing on the skin first, and then applying by dabbing at night with a Q-tip. You can start with two times a week. Olive oil is another option but may take longer to achieve growth." — Tedrick LaMar
