Get a brush. Face masks are best applied with a soft-bristle brush, such as a paintbrush (normally used for art making) or a tint brush (normally used to apply hair dye). Invest in a brush that you will use for this purpose, and be sure to clean it when you are done.
How to apply castor oil. Itâs best to use castor oil as a hair mask. This is particularly helpful if youâre trying to regrow hair or give it more moist and shine. Castor oil has a thick consistency, so you can mix it with coconut oil, olive oil or jojoba oil in a half and half ratio. This will make the mask easier to distribute throughout your hair. Use your fingers or a brush and start applying it onto your scalp with circular motions.
