With winters knocking on our door, our skin isn’t ready to lose its moisture all over again. When it comes to taking care of skin, just like any problem, prevention is better than cure. We are mostly too focused to protect our hair hence, forego the scalp, which is the actual breeding ground of our luscious locks.
If you have a dry, flaking scalp, you may suspect dandruff. But it could be a sign of dry scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions.
In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Knowing which of these conditions you have can help you get the right treatment and banish those flakes for good.
Causes and Symptoms
You get dry scalp when your skin has too little moisture. The skin on your scalp becomes irritated and flakes off. If your scalp is dry, the skin on other parts of your body, like your arms and legs, could be dry, too.
Dry scalp can also be triggered by factors like these:
- cold, dry air
- contact dermatitis caused by a reaction to products you apply to your scalp, like shampoo, styling gel, and hairspray
- older age
The skin cells on your scalp and body normally multiply when you need more of them. Then they die and shed off. When you have dandruff, skin cells on your scalp shed more quickly than usual.
If the cause is dry scalp, the flakes should disappear once you shower the next morning. Some hair stylists can perform a scalp treatment that uses steam to deliver more moisture to your scalp.
The main cause of dandruff is seborrheic dermatitis, a condition that turns the skin oily, red, and scaly. The white or yellow scales flake off, creating dandruff. You can get seborrheic dermatitis anywhere you have oil glands, including your eyebrows, groin, armpits, and along the sides of your nose. In babies, it’s called cradle cap.
Often, a fungus called Malassezia triggers dandruff. This fungus normally lives on your scalp. Yet some people have too much of it, and it causes skin cells to multiply more quickly than usual. Certain factors can cause Malassezia to multiply, including:
Dirty hair doesn’t cause dandruff, but if you don’t wash your hair often enough, the oily buildup can contribute to flakes.
One way to tell the difference between dry scalp and flakes from dandruff is by their appearance. Dandruff flakes are bigger and they look oily. In babies with cradle cap, the scalp looks scaly or crusty. Both dryness and dandruff can make your scalp itch.

Seeing a Doctor
You can treat most dandruff yourself with an over-the-counter shampoo – Selsun blue is a good option. If you’ve tried a dandruff shampoo for at least a month and your flakes haven’t improved, they’re getting worse, or the skin on your scalp looks red or swollen, make an appointment with a dermatologist, which is a doctor that specializes in treating the skin. You might have another skin condition that needs to be treated.

If you have dry scalp, wash with a gentle shampoo and then use a moisturizing conditioner. One way to tell whether you have dry scalp or dandruff is to apply a light moisturizer to your scalp before you go to bed. If the cause is dry scalp, the flakes should disappear once you shower the next morning. Some hair stylists can perform a scalp treatment that uses steam to deliver more moisture to your scalp.
For mild dandruff, wash your hair every day with a gentle shampoo to reduce the amount of oil on your scalp. If your dandruff is more severe or a regular shampoo doesn’t work, try a dandruff shampoo.

Most dandruff shampoos contain medicine that kills the fungus on your scalp or removes flaky skin. Here are some examples:
- Pyrithione zinc(Head and Shoulders) is an antifungal drug. It kills the fungus on your scalp that causes flaking. Pyrithione zinc shampoos are gentle enough to use every day.
- Selenium sulfide(Selsun Blue) reduces fungus and prevents too many skin cells from dying off. If you have blond or gray hair or you dye your hair, ask your doctor before using shampoo containing selenium sulfide. It can change your hair color.
- Ketoconazole(Nizoral) kills the fungus that causes dandruff. You can buy it in over the counter or prescription strength.
- Salicylic acid(Neutrogena T/Sal) removes extra scale from your scalp before it can flake. In some people, salicylic acid can dry out the skin and cause more flaking.
- Coal tar(Neutrogena T/Gel) slows the growth and shedding of skin cells on the scalp. Tar-based shampoos can also change your hair color if you have blond or gray hair.
Shampoos containing tea tree oil are an alternative remedy for dandruff. Tea tree oil is a natural ingredient with antifungal properties. An older study from 2012 showed that a 5 percent tea tree oil shampoo reduced scaling without causing side effects. Some people are allergic to tea tree oil. Ask your doctor before you try it. Stop using the product if you have any redness or swelling.

No matter which dandruff shampoo you try, read the instructions on the bottle and follow them carefully. If you’re not sure which shampoo to use or how often to use it, ask your doctor or pharmacist for advice. You might have to try a few brands before you find one that relieves your dandruff.
Once your dandruff improves, you might be able to cut back on the number of days that you use the shampoo. For more stubborn dandruff, your doctor can prescribe a stronger shampoo or a steroid lotion.
Here are some tips to prevent dandruff and dry scalp:
- If you have dandruff, wash your hair often with an antidandruff shampoo. Make sure to rinse out all the shampoo.
- Avoid using hair products that contain harsh chemicals, like bleach and alcohol. These ingredients can dry out your scalp. Also avoid oily hair products that can build up on your scalp.
- Spend a few minutes out in the sun every day. There’s some evidence that ultraviolet light exposure can help control dandruff. Yet you don’t want to get too much sun exposure because it can increase your risk for skin cancer.
