1. Tame flyaways.
You know those wispy baby hairs that stick out when you tie your hair into a ponytail? Yeah, those things are annoying. Here's a super quick solution: Apply hair serum or hairspray on a toothbrush, and use it to smoothen out those flyaways. You'll get super sleek hair—without OD'ing on products.
Those yellow armpit stains are a nightmare to get rid of—especially on a plain white tee. Mix equal parts of baking soda, hydrogen peroxide, and water together. Then use a toothbrush to apply the solution to the stain. Leave for 30 minutes, and toss in the washing machine after.
3. Use it as a lip exfoliator.
You don't need an expensive lip scrub to keep your puckers kissable. After brushing your teeth, use the toothbrush to exfoliate your lips gently (when they are still damp). That way, you slough off dead skin, making lippie application a B-R-E-E-Z-E!
4. Tame your brows.
No brow brush? Use a toothbrush to tame unruly eyebrows.
5. Clean your hairbrush.
Some bristle-to-bristle action between your toothbrush and hair brush ought to remove the tangled hair stuck on the base of the latter.
