This is cheaper than the ones you buy and works
as well.
Carefully wash a small jar container with a lid and fill with 1/4 T Castor Oil, 1/4 T Aloe Vera Gel and 1/2 T Vitamin E Oil. Mix the concoction together thoroughly. Buy a new mascara brush and apply a light layer to lashes or brows every night before bed. Castor oil thickens your lashes while Aloe Vera gel lengthens. Vitamin E speeds up the length. After one month, you'll notice stronger, longer, more beautiful eyelashes.
