It is not uncommon for your scalp to itch, but when it does, there is an underlying cause for this. If your scalp itches all of the time, that is an important sign not to overlook. There are some situations in which that itchy feeling is more than just an annoyance. In some situations, it can lead to the development of conditions that cause hair loss. If you already have hair loss and your scalp is bothersome like this, it may be time to speak to your doctor about what is behind it.
