If you have alopecia areata, it generally doesn't cause pain or other symptoms. However, some people say that right before they lose their hair, they feel tingling, itching, or burning on the skin where the hair will fall out.
Patients with active alopecia areata often complain of mild itching or burning, which often precedes development of new patches. It may be caused by mast cell release of histamine and tryptase as well as lymphocytic infiltration with release of IL-31 .
Alopecia areata is a condition that can cause all or patches of a person's hair to fall out. It can also lead to scalp itchiness.
There can be several causes of the itchy feeling that alopecia areata patients feel at times. One reason for this is due to flaking skin or scaly patches on the scalp. Another reason is that alopecia areata can also cause an itchy feeling on the skin due to stress and anxiety.
Patchy hair loss (alopecia areata)
In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap.
It is believed that the person's genetic makeup may trigger the autoimmune reaction of alopecia areata, along with a virus or a substance the person comes into contact with. Alopecia areata is an unpredictable disease. In some people, hair grows back but falls out again later. In others, hair grows back and remains.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
Minoxidil, commonly known as Rogaine, is a topical treatment that's easy to apply and can be easily purchased over the counter. Minoxidil works to help the hair grow faster once the follicle is no longer under attack by the immune system and is capable of producing hair.
Not all people with alopecia areata require treatment; many patients with limited disease will experience spontaneous hair regrowth.
Scalp pruritus  or itchy scalp can be a result of fungal infections, allergic reactions to hair care products or inflamed hair follicles. All these may damage the hair follicles and cause hair loss. Scalp itching, which is a result of dandruff, can cause itching and scratching.
The extent of alopecia (how much hair has fallen out) varies and links to the different subtypes. Some said their hair loss involved one small patch about the size of a 1p coin which regrew after a few weeks or months. Others developed more patches which sometimes joined up into bigger bald areas over time.
Most people know alopecia to be a form of hair loss. However, what they don't always know is that there are three main types of the condition – alopecia areata, alopecia totalis and alopecia universalis.

Female-pattern baldness is a pattern of hair loss (alopecia) caused by hormones, aging and genetics. Unlike male-pattern baldness, female-pattern baldness is an over-all thinning which maintains the normal hairline.

The term end stage scarring alopecia is often tacked onto the report when the pathologist sees lots of scarring and little in the way of inflammation. To the pathologist, the finding of ESSA implies that hairs in the biopsy have been destroyed and there is not much left anymore to destroy.
Is alopecia contagious? Alopecia is not contagious. Individuals who develop alopecia areata typically have both a family history and some type of environmental trigger, such as emotional or physical stress.
Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels. Vitamin D should be supplemented if levels are low.
Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN- γ is one of the key factors that lead to the collapse of immune privilege.
Can a Blood Test Detect Alopecia? Yes, a blood test can diagnose alopecia. Your doctor may order several blood works to determine the cause of the hair loss along with a scalp biopsy.
