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.
Sudden Loss of Patches of Hair
Bald spots may grow very slowly in one area or you may notice a patch or strip of hair loss that appears within just a day or two. In some cases, you may notice burning or stinging before sudden hair loss.
Alopecia (hair loss)
When hair follicles are damaged or irritated, it can cause itching or tingling, as well as areas of hair thinning. When tingling, discomfort, or pain in the scalp results from hair loss, the symptom is called trichodynia.
Alopecia areata typically begins with sudden loss of round or oval patches of hair on the scalp, but any part of the body may be affected, such as the beard area in men, or the eyebrows or eyelashes.
The main symptom of alopecia areata is hair loss that occurs in small, round patches on your head. This leaves smooth, peach-colored areas of scalp exposed. A mild case of alopecia areata starts with one to two coin-size hairless patches. In many instances, it stops after that.
An increasingly common hair loss pattern in older women is a receding hairline (frontal fibrosing alopecia). Circular or patchy bald spots. Some people lose hair in circular or patchy bald spots on the scalp, beard or eyebrows. Your skin may become itchy or painful before the hair falls out.

Alopecia and hair loss
A form of hair loss called alopecia areata can also cause scalp tenderness. In this condition, hair follicles fall out in round clumps from the scalp and sometimes the body. Alopecia areata presents in patches, while alopecia totalis involves the loss of all hair from the head.
What causes alopecia areata? Alopecia areata is an autoimmune disease. This means that your immune system mistakenly attacks a part of your body. When you have alopecia areata, cells in your immune system surround and attack your hair follicles (the part of your body that makes hair).
Cluster, eyestrain, and tension headaches may all trigger a tingling sensation in the head due to changing pressure and blood flow. A migraine aura may occur before a migraine episode. A tingling sensation is a common part of migraine auras.
A tingling feeling in the scalp (paresthesia) can occur for many reasons, including anxiety, ASMR, chemical irritation, medication, migraines, nerve compression, skin sensitivity, and underlying health conditions. If you have chronic (ongoing) scalp tingling, see your healthcare provider.
Formication is also a type of paresthesia which is defined as tingling dermal sensations. Causes of crawling sensations on the scalp include delusional infestations, hallucination, substance abuse, a parasitic infestation, side effects from medication, or issues with the neurologic system.
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30. Alopecia areata is not life-threatening and does not cause physical pain. However, the psychosocial effects of hair loss can be devastating.
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.
Alopecia areata frequently presents as the sudden onset of smooth, round, hairless patches on the scalp. The affected areas are usually skin-colored but may have a peach color. Occasionally, there are scattered short colored or white hairs within the hairless patch.
A sore scalp can be caused by infected hair follicles, scalp pimples, or tension from certain hairstyles that may pull the hair too tight. Other causes for scalp tenderness include trauma from a head injury, or underlying skin condition like eczema or cellulitis.
Possible causes
scalp psoriasis. seborrheic dermatitis (dandruff) scalp folliculitis. allergic contact dermatitis.
Migraine headaches cause intense, throbbing head pain. These headaches also can make your nerves so sensitive that even the slightest touch hurts. This is called allodynia, which means "other pain." Up to about 80% of people with this condition have allodynia during an attack.
Thankfully, mild cases of alopecia areata often get better without treatment within a few months to a year. In some cases, patchy baldness may come and go over many months or years. The size of the bald patch or patches and how long they last are quite variable.
It is not contagious; you can't catch AA from someone who has it. Researchers believe AA is an autoimmune disease such as rheumatoid arthritis, but in this case the individual's own immune system attacks hair follicles instead of bone joints.
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.
