Your Hair-Washing Routine Should Change As You Age—Here’s Why
Summary
As people get older, their scalp and hair change in ways that affect how often they should wash their hair. Experts say that because the scalp produces less natural oil with age, washing hair less often—about every two to three days—is better to keep the scalp healthy and avoid dryness and irritation.Key Facts
- The scalp makes more natural oil (sebum) in young adulthood, which helps protect hair and scalp.
- After the 20s, oil production steadily goes down, causing the scalp to become drier and more sensitive.
- Less oil means the scalp loses moisture faster and takes longer to heal from irritation.
- Hair strands get thinner, weaker, and the outer protective layer becomes more fragile with age.
- Hair growth slows down, and hair follicles shrink or stop producing hair, leading to thinning.
- Hormone changes, especially lower estrogen, can cause hair texture changes and thinning.
- Younger people with oily scalps may wash hair daily, but older adults should wash every two to three days or less.
- Not washing hair for more than 7-10 days is not recommended because the scalp still needs regular cleaning.
