Stand in front of a mirror, and try to lift your right eyebrow. Then try to lift only your left eyebrow. Which one do you feel that you have better control over? This is likely your dominant eyebrow, and the one you should try to focus on. Don’t worry if you feel you don’t have control over either, just pick one and go from there. Make a note of which eyebrow you will focus on. This way you won’t get mixed up and waste time trying to train both eyebrows at the same time.
Place tape over the raised brow instead of using your hand if this feels more comfortable. Doing this gives you more muscle control since you’re not relying on your hand to lift the brow. It also forces you to assist in the process of holding the brow up by straining those muscles. With your eyebrow still raised, trace your finger over the muscles along the brow bone. They should feel taut. These are the muscles you want to focus on when you’re lifting the brow. Even if you are primarily using your hand to practice, this is a good exercise to help you remember where the brow muscles are located.
Practice this for 2-5 minutes each day.
Again, do this for 2-5 minutes each day. It is conceivable that some people simply may not be able to individually lift a brow without using the hand as a guide. However, you’ll probably need more practice to be able to tell if this is the case. Even people that eventually are able to do it usually require some form of training, so you won’t know until you give it a try for a little while.
