Try a strawberry scrub

Dark nail polish, hormone fluctuations and friction from footwear can all cause nails to take on a yellowish tinge. But a scrub made of strawberry and baking soda can help! The berry’s malic acid and vitamin C lift stains and brighten nails, while abrasive baking soda removes any discoloring buildup on the nails’ surface. TO DO: Mix 2 mashed strawberries and 1 Tbs. of baking soda. Buff onto nails with a clean toothbrush for 1 minute; let sit for 15 minutes, then rinse. Use twice a week for results in one month.
