Welcome again to EmpowHER. That is an interesting question.
Experts say there's no single answer to how often people should shampoo. You may not need to do it as often as you think. It usually comes down to personal preference. For guidance, take a look at your hair type and styling choices.
Shampoo traps oils, so if you do it too frequently, you may dry your hair out, leaving it prone to breakage, says Angela Lamb, MD, an assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City.
The experts agree that only a small group needs to shampoo daily, like those with very fine hair, someone who exercises a lot and sweats, or someone living in very humid place.
A very individual choice!
