or hair dye, that you use on your hair or scalp can cause red, flaky skin.
Once you’ve figured out the underlying cause of your dandruff, you can more effectively treat it.
Use a medicated shampoo
If you haven’t already, try using a medicated shampoo designed to help with dandruff. Look for products containing any of the following ingredients:
- pyrinthione zinc
- salicylic acid
- selenium sulfide
For mild cases of dandruff, you may only need to use medicated shampoo for a few weeks.
If you have light-colored hair, you may want to stay away from selenium sulfide, which can cause discoloration.
Regardless of the underlying cause of your dandruff, it’s important to hydrate your scalp with conditioner. This is especially important when using medicated shampoos, especially those containing salicylic acid. These can be drying when used regularly.
For an added benefit, try massaging your scalp with coconut oil, then rinse it out. In addition to being moisturizing, coconut oil has antifungal properties. In fact, a 2015 study found that its antifungal activity was similar to that of ketoconazole, a common ingredient in antidandruff shampoos.
Steer clear of using oils on your scalp if you think you might have seborrheic dermatitis. Extra oil can sometimes make this condition worse.
Avoid irritating hair products
Hair dye and other hair products often contain ingredients that can irritate sensitive skin. This can lead to contact dermatitis. Preservatives and fragrances are common causes of contact dermatitis on your scalp.
Examples of potentially irritating ingredients in hair products include:
- natural or artificial fragrance
Some people use products for years before noticing any kind of reaction. Even if you’ve used the same hair products without any problems, consider changing up your routine if you notice dandruff.
While stress won’t directly cause dandruff, it can weaken your immune system over time. This can make your scalp more sensitive to naturally occurring malassezia fungus. Learn more about the effects of stress on your body.
Get a little sun
Though ultraviolet rays cause premature aging and increase your risk for skin cancer, a little bit of sunlight may be good for dandruff, according to the Mayo Clinic. If you head outside, be sure to wear sunscreen on your face and body.
Having dandruff doesn’t immediately lead to hair loss. However, constantly scratching your scalp can damage your hair follicles and lead to some hair loss. This isn’t permanent and should resolve once you find out what’s causing your dandruff. If you don’t already know the cause, your doctor or dermatologist can help.
