Updated April 17, 2017

If you experience an itchy scalp occasionally, it may be nothing to worry about. But reoccurring itchy scalp and hair loss can be frustrating. There are many different reasons why this can happen. It is important to find out the cause of your itchy scalp, so that you can get the treatment needed to stop the hair loss. You should also be concerned that you do not have any ailment that can be spread to your family.

Dry Scalp

Over-washing hair or using a harsh shampoo is one cause of dry scalp. If you have dandruff, chances are you have dry scalp. The dandruff blocks the pores and can also cause hair loss.


If you have excessive itching of all of sudden, you will need to check your scalp for lice. Lice are tiny insects that are a grey colour. If you have lice you will need to seek treatment right away because lice can be spread from person to person.


Any new product you use in your hair may cause an allergic reaction. When purchasing hair colouring or any chemical hair product, it is a good idea to check the labels for any ingredient you are allergic too.

Oily Hair

A build-up of oils from dirty hair can clog the pores on the scalp. This does not allow the scalp to breathe.

Scalp Conditions

Scalp disorders like Psoriasis, or Dermatitis cause patchy skin irritations that cover the entire head. Most people with these conditions have the rashes on other parts of their body as well. But some only have the condition on their scalp. These conditions require medical attention.
