How to Cure Smelly Scalp

Washing Your Hair with Medicated Shampoo

Purchase a shampoo that contains tar, sulfur, or zinc. Read the label on the shampoo bottle to see if it contains these ingredients. Tar, sulfur, or zinc are often included in anti-dandruff shampoo, so check these types of shampoos. These ingredients may help to eliminate any odor-causing bacteria on your scalp.

Use the shampoo daily or every other day. Wet your hair thoroughly with warm water, then massage ⁄2 to 1 US tbsp (7.4 to 14.8 mL) of shampoo into your scalp and hair for treatment. Continue to work the shampoo into a lather for about 30 seconds. Then, rinse your hair with warm water until all the suds are gone and the water runs clear.Tip: Don’t go more than 3 days without shampooing your hair as this gives bacteria a chance to build up.

See a doctor if the odor doesn’t improve within 2 weeks. You may notice an improvement in your scalp odor within the first few uses/treatments, or it might take a little longer. If you don’t see any improvement in the odor coming from your scalp within 2 weeks after you start using a medicated shampoo, make an appointment with your doctor or a dermatologist. They can prescribe a stronger medicated shampoo to help stop the odor. Your doctor or dermatologist may also want to test a sample of your hair or take a swab of your scalp to determine what might be causing the odor.

Maintaining Good Scalp Hygiene

Condition your hair from the middle of the shaft to the ends only. Don’t apply conditioner to your scalp as this may cause smelly bacteria to build up since it creates a moist environment. You can skip the conditioner if you like, or apply it to the middle of your strands and down to the ends. Leave the conditioner on for about 30 seconds and then rinse it off with lukewarm or cool water.Tip: Some shampoos are 2-in-1 varieties, so you can skip conditioning your hair if you use this type.

Apply a dry shampoo between washes to absorb oil and odors. Spray the dry shampoo onto your roots and massage it into your scalp and hair with your fingertips. Then, brush through your hair to distribute the dry shampoo. If you prefer not to wash your hair every day, applying a dry shampoo is a good way to reduce excess oil. This may also help to prevent bacteria (and smells) from building up. Make sure to choose a dry shampoo with a clean, fresh scent.

Launder your towel at least once per week. Reusing the same towel over and over again to dry your hair after a shower can reintroduce bacteria into your hair after you wash them out. If you do reuse your towel, don’t reuse the same towel for more than 1 week. Also, make sure that it is spread out on a towel bar after each use so it dries out completely. Launder hats, cloth headbands, and scarves after each use as well.

Change your pillowcase every other day. Put a fresh, clean pillowcase on your pillow before you go to bed each every other night of the week. Chuck the dirty pillowcase in the laundry and slip a new one on. Odors and bacteria may get onto your pillowcase while you sleep and, if you don’t change it regularly, they may end up back in your hair.

Trying Natural Home Remedies

Shampoo your hair with baking soda 1-2 times per week if it’s oily. Dispense about 1 tablespoon (15 g) of baking soda and then massage it into your scalp just as you would with shampoo. The powder will exfoliate and deodorize your scalp. Do this in place of shampooing your hair 1-2 times per week until the problem goes away. As a bonus, the baking soda will remove built-up hair product and give your hair more volume.

Repeat the treatment 1-2 times weekly.Variation: Try mixing 2–3 drops of peppermint, rosemary, or lavender essential oil into a 1 tablespoon (15 ml) of a carrier, such as almond or coconut oil.

Rinse with apple cider vinegar for shiny, deodorized hair. After shampooing your hair, pour 8 fl oz (240 mL) of apple cider vinegar over your scalp and hair.
