Alopecia areata affects people of all ages including young children. It produces circular patches of hair loss that appear overnight. More patches appear over time and eventually about 5% of people affected lose every hair on their body.
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.
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 is a form of alopecia (hair loss). It's a non-life-threatening disease of your immune system that affects the hair on your scalp. With this condition, your body mistakenly views your hair follicles as an enemy. Your body attacks the hair follicles.
Yes, stress and hair loss can be related. Three types of hair loss can be associated with high stress levels: Telogen effluvium. In telogen effluvium (TEL-o-jun uh-FLOO-vee-um), significant stress pushes large numbers of hair follicles into a resting phase.

Scarring or cicatricial alopecias represent a group of poorly understood and uncommon disorders that cause permanent hair loss. Scarring alopecias are regarded as trichologic emergencies as hair loss is irreversible, rapidly progressive, and can be disfiguring.
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.
Alopecia areata
It develops when your immune system attacks your hair follicles. This may be triggered by stress, and it can result in hair loss. Hair may be lost in round patches on the scalp, or across the entire scalp. In a more severe form of AA known as alopecia universalis, hair is lost from the entire body.
There is currently no cure for alopecia areata, although there are some forms of treatment that can be suggested by doctors to help hair re-grow more quickly. The most common form of alopecia areata treatment is the use of corticosteroids, powerful anti-inflammatory drugs that can suppress the immune system.
Alopecia, more commonly referred to as hair loss, is a problem faced by millions of people in the United States. Alopecia does not refer to normal, everyday loss of hair. It is common for a person to lose around 50 to 100 hairs each day. Alopecia suggests an amount of hair loss greater than what is normally expected.
Alopecia areata often happens once and then there is regrowth of normal hair. Sometimes, recurrent episodes of hair loss may occur with periods of regrowth. This may occur over many years.
Alopecia areata incognita (AAI) was first described by Rebora2 in 1987. The disorder has an extremely acute onset with subsequent diffuse hair loss that occurs within a few weeks.
The Ludwig scale defines three broad stages of hair loss. In stage 1, the hair on the top of the head begins thinning. In stage 2, the scalp starts to become visible. In stage 3, all of the hair at the crown may be lost, resulting in baldness.

The human body produces the hormone melatonin. This hormone has been confirmed by researchers to regulate the sleep cycle and increase hair growth. While sleep has a direct impact on the human body's natural hormones, it means that poor sleep reduces the amount of melatonin, potentially cause hair loss.
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.
