These ingredients can help treat multiple bacteria-related conditions on the scalp. Here’s the DL.


Bacterial folliculitis is inflammation of the hair follicles, typically due to Staphylococcus aureusinfection. You may notice symptoms like:

  • inflamed skin
  • brown or yellow scabs
  • pimples or whiteheads
  • pus-filled or crusty sores
  • itching, burning, or tender skin

Antibacterial shampoo can help curb the bad bacteria and get your scalp back on track.


Dandruff is often caused by a fungal infection on the scalp. However, a bacteria called Malassezia globosa can also play a part. This single-celled microbe feeds on the delicious oils produced by your skin. This can turn your once flake-free scalp into the Itchy & Scratchy Show.

Antibacterial shampoos containing triclosan and zinc pyrithione might help resolve your flaking, itchy scalp. But your doc might also suggest an anti-fungal shampoo or rinse, too.


Impetigo is a mild skin infection that’s caused by Streptococcus and Staphylococcus aureus. The infection can pop up anywhere on your bod. Common symptoms include itchy, red sores that can leak pus or clear fluids.

Antibacterial shampoo can help resolve symptoms and may provide relief from itching.

Antibacterial shampoo is generally safe when used correctly. However, there are some potential probs to keep in mind.

For peeps with sensitive scalps, the ingredients in antibacterial shampoos can cause:

  • redness
  • irritation
  • burning

  • inflammation

Itching is also a common side effect. If you experience any of these symptoms, stop using the shampoo and see your doc if the symptoms don’t improve.

P.S. Antibacterial shampoo can kill good and bad bacteria. The imbalance of microbes can sometimes cause more problems than it solves. So, unless you have an actual condition that needs to be treated with antibacterial shampoo, stick to your normal haircare routine.

Your healthcare provider can prescribe stronger medicated shampoos or give you other treatments. In some cases, you may need antibiotics to clear the infection.
