Here’s how often you should wash your hair, according to a dermatologist

The Factors That Dictate Your Routine

Dermatologists suggest that your washing frequency should be determined by three main variables: oil production, activity level, and hair texture.

1. Sebum (Oil) Production

Your scalp produces a natural oil called sebum. If you have fine hair or a naturally oily scalp, you may need to wash every day or every other day to prevent clogged follicles. Those with thicker or natural hair textures often find that sebum takes longer to travel down the hair shaft, allowing for more time between lathers.

2. The Sweat Factor

For those who engage in consistent physical movement—such as teaching or practicing movement flows—sweat can be a major factor. While sweat itself isn't oily, it can trap dirt and bacteria against the scalp.

• The Rinse Rule: If you’ve had a heavy session but don't want to strip your hair with shampoo, try a thorough water rinse followed by conditioner on the ends.

• Post-Sweat Care: Focus the shampoo only on the scalp to remove salt buildup without drying out the lengths.

3. Environmental Exposure

If you spend time in high-heat environments, such as a sauna or a heated studio, your scalp may require extra attention. Heat opens the hair cuticle, making it more prone to moisture loss, but it also increases perspiration.

Can You "Train" Your Hair to Be Less Oily?

You may have heard that if you stop washing your hair, your scalp will eventually stop producing so much oil. Most dermatologists agree this is a myth. Your oil production is largely hormonal and genetic. While you can't "train" your sebaceous glands to shut down, you can train your hair to look better between washes by using dry shampoos or opting for sleek, pulled-back styles during high-activity days.

The Dermatologist's Bottom Line

The best indicator of when to wash is your scalp's comfort. If you notice itching, redness, or visible flaking, it’s a sign that buildup is causing irritation. Conversely, if your hair feels brittle and snaps easily, you are likely over-cleansing.

For those who prioritize wellness and recovery, treating your hair care as part of your overall hygiene routine—adjusting for sweat and heat—is the key to maintaining a healthy, vibrant head of hair.
