The only benefit you can get from skipping washes is preventing it from getting too dry due to excessive use of shampoo.

Many people wash hair daily with shampoo. The presence of chemicals in shampoo not only remove dirt and grime but they can also strip off natural oil from the scalp when used daily (1). As a result, the hair become dry and frizzy. The lack of moisture in hair also contributes to making them prone to breakage.

Here, it is essential to mention that all these adverse effects are only due to excessive use of shampoo, especially since it is not gentle on the scalp and hair. If you are over-washing hair or using shampoo every morning while taking a bath, you could experience all of these, which may eventually result in hair loss.

  • Natural oils called sebum create a thriving environment for bacteria
  • Sweat provides moisture that favors bacterial growth on the scalp
  • Product buildup attracts bacteria
  • Environmental pollutants accumulate over time, inviting bacteria to thrive

On the other hand, people who do not develop sweat often and have dry scalps should wash only after 2 to 3 days to keep the scalp clean and hair healthy. Remember, a healthy and clean scalp ensures faster hair growth.
