Dip a cotton ball into the lemon juice and baking soda solution and apply it to your teeth. Let the lemon and baking soda solution sit on your teeth for around a minute. Brush your teeth to remove the acid. I saw results the first time I tried this.
I may no longer have to be jealous of my little brother's awesome eyelashes... Wash an old mascara or nail polish container and fill with: 1/4 of the container with Castor Oil, 1/2 Vitamin E Oil, 1/4 Aloe Vera Gel. Mix the concoction together as well as you can with your mascara wand, 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 accelerates length. Give it a month for results.
