Dry scalp and dandruff can both cause an itchy, flaky scalp. This can sometimes make it hard to tell the difference. However, excess oil causes dandruff, and loss of moisture causes dry scalp.
When you have too much oil on your scalp, your skin cells can build up. Your scalp may appear red, oily and scaly. The scales quickly flake off, and then dandruff appears. Dandruff looks like larger pieces of dry skin flaking off your scalp. It frequently comes and goes and is a very common condition.
Seborrheic dermatitis is the main cause of dandruff. Seborrheic dermatitis is a skin condition with various causes. Yeast that lives on your skin, stress or your health can all cause seborrheic dermatitis. Babies can get seborrheic dermatitis, too. If your baby has a scaly, dry scalp, it’s called cradle cap.
While a dry scalp can cause itching and flaking, it’s different than dandruff. If you have a dry scalp, the rest of your body may experience dryness too. In addition, the cause of the condition is different. The loss of moisture can be due to many factors, including various skin conditions.
If you’re wondering why your scalp is so dry, you’ll need to consider several reasons. The products you use on your hair could be causing contact dermatitis. Contact dermatitis is a reaction to something that causes itchiness and irritation. Many hair care products dry out your hair by stripping it of its natural oils, which can leave your scalp irritated.
The weather could also be causing your condition. Environments with low humidity and areas located in cold climates can dry out the skin on your scalp. In addition, as you get older, your skin starts to dry out. However, the condition can occur for more serious reasons. These conditions may include:
Psoriasis is a long-term (chronic) skin condition that causes your skin cells to grow too quickly. This rapid growth makes your skin cells pile up on the surface of your skin in patches. These patches are called plaques. Psoriasis has many genetic components, but other factors may trigger it as well. These factors include infections, injuries and medications. It also includes lifestyle factors such as drinking alcohol or smoking.
Tinea capitis, or scalp ringworm, is a fungal infection of the skin on your scalp. Tinea capitis spreads very easily. You can get it through direct contact with other people and animals. You can also get it by sharing objects, such as hats and brushes, and by touching surfaces that harbor the fungus. Tinea capitis can live for a long period of time on infected surfaces and objects.
Actinic keratosis, or solar keratosis, is a type of precancerous sun damage caused by unprotected sun exposure. It’s most common in people assigned male at birth who’ve experienced hair loss, because they have less protection from the sun. Actinic keratosis is also common in people who are age 50 or older who spend a lot of time outdoors without sun protection. Genetics and family history can also play a role.
Dry scalp treatment depends on the cause of the condition. If hair products have caused the condition, you may just have to do a better job rinsing out your shampoo. Shampoo that’s left behind after you shower could be irritating your scalp.
If that doesn’t work, you may be able to try home remedies for your dry scalp. If a hair care product is causing contact dermatitis, you may have to stop using that product. You can usually get rid of dry scalp by switching to a non-medicated, gentle shampoo. A shampoo for dry scalp helps stop the dryness and flakes.
If a more serious health issue is causing your condition, call your healthcare provider. A dermatologist can diagnose your condition and help fix your dry scalp. Treatments may include:
Your dermatologist may prescribe a medicated ointment or cream such as a corticosteroid to apply to your scalp. Corticosteroids reduce itching, redness and scaling quickly. Your dermatologist may also recommend:
