Hair loss is one of the most common conditions affecting people all over the world. While it is a natural part of aging, there can also be medical reason behind it. One of the most common reasons is alopecia areata. This is not as simple as you may think, because even this condition can be a sign of a much deeper problem. This article will give you more insight into the causes, symptoms and treatments for alopecia areata. If you’re interested, keep reading.
Alopecia areata is actually diagnosed by the initial bald spots it causes on the head. For this reason, it is sometimes referred to as ‘spot baldness’. This can be easily confused with the standard hair loss that comes with age. However, the condition can develop into two different types if left untreated, including:
- Alopecia Universalis: this type affects hair on the entire body
- Alopecia Totalis: this type affects hair on the scalp
The condition is mainly associated with various thyroid disorders, where the hormonal balance in the body in charge of maintaining the health of the hair follicles is thrown off balance. It is better to treat the condition while it is still mild, as it may get worse overtime. There are also times when situational or psychological factors cause some small flare-ups of hair loss and alopecia. In these cases, the condition generally fixes itself and the hair grows back.
