Updated on December 2, 2013

What is an Itchy scalp?

This is an inflammatory reaction of your skin that is underneath your hair. It is a common problem, especially among adults. How severe, how long it will last, and how frequent a person will have an itchy scalp depends on what is cause the itch. There are many different causes to have this medical symptom.

Itchy scalp and Hair loss

Having an itchy scalp is bad enough but when you combine it with hair loss it can be very frustrating. It can also be a cause for a person to worry, especially if it is a woman who is experiencing the hair loss. Most of the time hair loss that is caused by an itchy scalp is not permanent. The hair will grow back but this will only happen if you have the right treatment.

Some of the treatments that a person can use if experiencing an itchy scalp and hair loss may include:

  • Changing your shampoo and/or conditioner to see if either of these two products are causing the problem.
  • Keep your hair and scalp clean which means that you may have to wash your hair more frequently, especially if your hair and scalp get dirty and greasy on a daily basis. You may have to wash your hair every day.
  • You should avoid chemical and heat treatments but if you do get either of these treatments you should make sure that you are using the right hair care products for these treatments on a regular basis.
  • Make sure that your diet is rich in vitamin B and folic acid.
  • Eat a variety of vegetables, especially spinach and lettuce.
  • Get the right amount of protein in your diet by including such foods as eggs, milk, and dairy.

One of the main reasons a person can loose hair due to an itchy scalp is the excess secretion of oil from your scalp, which can cause inflammation, persistent flaking, and extreme itching and can lead to bacterial infections. Scalp psoriasis is another cause.
