What causes a dry itchy scalp?

There are many potential causes of a dry and itchy scalp. Medical conditions like eczema, psoriasis, and seborrheic dermatitis can all cause dryness and itchiness. Allergies to certain hair care products, such as shampoos, conditioners, or dyes, can also cause these symptoms. Weather conditions, such as cold weather or low humidity, can also lead to a dry and itchy scalp.

Some people may also experience a dry and itchy scalp as a result of over-washing or using harsh cleansers. This can strip the scalp of its natural oils, leading to dryness. If you suspect that your dry and itchy scalp is due to over-washing, try cleansing your hair less frequently or using a milder shampoo.

A dry itchy scalp can be caused by a number of things. It could be due to dandruff, psoriasis, seborrheic dermatitis, or even eczema. Hair products, hard water, weather, and stress can also play a role in making your scalp dry and itchy. If you're not sure what's causing your dry itchy scalp, it's best to see a doctor or dermatologist so they can properly diagnose and treat the issue. There are many possible causes of a dry and itchy scalp. Some common causes include:
  • Dandruff
  • Seborrheic dermatitis
  • Psoriasis
  • Dry skin
  • Allergies
  • Hair products

If you're experiencing a dry and itchy scalp, you should talk to your doctor to rule out any underlying medical conditions. You may also want to try changing your hair care products or using a medicated shampoo.

If you're noticing a dry itchy scalp, there are a few possible causes. It could be due to weather conditions, dandruff, or even something more serious like psoriasis. Let's take a closer look at each of these possibilities.

Weather Conditions

If the air is particularly dry, it can lead to a dry itchy scalp. This is especially common in the winter when indoor heating sucks the moisture out of the air. If this is the case, you can try using a humidifier in your home to add some moisture back into the air. You can also try changing your shampoo to one that is more hydrating.


Dandruff is another common cause of a dry itchy scalp. It's caused by a fungus that lives on your scalp and feeds on the oils produced by your skin. This can lead to flaking and itchiness. There are a number of anti-dandruff shampoos on the market that can help to get rid of this problem.


Psoriasis is a condition that causes the skin to produce too many cells. This can lead to patches of thick, scaly skin. It can also cause itchiness and redness. If you think you might have psoriasis, it's important to see a doctor so they can confirm the diagnosis and prescribe the appropriate treatment.
