I tried this on my hair, but it's a bit shorter so had to tweak it a little. I gathered more hair into the braid halfway down. Pulled it into the pony, then wrapped hair around the rubber band. LOTS OF TEASING WAS INVOLVED TOO! Works best on dirty hair.
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.
