Makeup brushes can become coated not only with makeup residue, but also with body oils and dead skin, making them havens for bacteria that will decrease the life of your brush, negatively affect the proper application of makeup and can also cause skin problems and possible infection. It is recommended that you clean your makeup brushes at least once a week. Be aware that the brush handle and bonding must be keept free of water, otherwise you risk the hair begins to trap because the glue breaks. Therefore, keep the brush with hair down under the whole washing process.

  • Once a week, fill your sink or small bowl with a couple of inches of warm water (depending on how many brushes you have to wash) and add a capful of shampoo (about a tablespoon) and a 3-4 drops of Tea Tree oil or olive oil (available at most drug stores and beauty supply stores), and work into a sudsy mixture.
  • Place your brushes in the solution and gently rub the bristles between your fingers for at least 30 seconds for each brush.
  • Rinse each brush thoroughly in warm water, making sure to get all shampoo residue off.
  • Pat the brushes dry with the towel, then lay them flat on the towel, reshaping the bristles, and keep them in a warm, dry location to finish air-drying completely. You may need to reshape the bristles on the brushes to retain their proper shape after they dry.
