Will vegtable oil help eyebrows grow?

While vegetable oil may help moisturize your eyebrows, there is no scientific evidence to suggest that it can help them grow thicker or longer. For brows, you can try coconut oil, almond oil, castor oil or olive oil. However, if you are experiencing sparse or thinning eyebrows, it's best to consult with a dermatologist or trichologist for proper diagnosis and treatment options.
