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.
Bald spots of the scalp, brow, or beard are commonly caused by a medical condition called alopecia areata. It is also commonly called spot baldness, and it is believed to be an autoimmune disorder that causes the body's immune system to mistake hair follicles for foreign invaders, and then, attack them as such.
People with certain autoimmune diseases, such as psoriasis, thyroid disease, or vitiligo, are more likely to get alopecia areata, as are those with allergic conditions such as hay fever.
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.
Make an appointment to see your doctor if: You suddenly develop a bald spot on your scalp. Your hair stylist tells you that your hair is thinning, or that you have small bald areas. You have lost your eyebrows or eyelashes, your beard is thinning, or you have noticeably less hair on your underarms or pubic area.
In most people, new hair eventually grows back in the affected areas, although this process can take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
Stress-related hair loss, also called telogen effluvium, typically starts 2 to 3 months after a stressful event and can last for up to 6 months.
Alopecia is the medical term for hair loss, and it can be caused by genetics, hormonal imbalances, lifestyle factors such as how you wear your hair, medical treatments like radiation or chemotherapy, or even a very stressful event.
After controlling for age, high cholesterol, smoking and other variables, they found that hypertension was “strongly associated” with male pattern baldness: those with a blood pressure reading above 120 over 80 had twice the risk of the others.
Sudden hair loss is typically a sign of two conditions: telogen effluvium or alopecia areata. Telogen effluvium is commonly caused by stress, which increases the natural rate of hair loss. Alopecia areata is an autoimmune condition that causes your body to attack its hair follicles, resulting in hair loss.
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.
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.
Hair Loss in Your 20s
The majority of androgenetic alopecia (or male pattern baldness) sufferers start noticing their hair loss in their mid to late twenties.
Hair loss can be a sign of male-pattern baldness, a fungal infection or something more serious, such as a thyroid condition. If you have hair loss that you feel is abnormal, it's best to see your doctor about it, especially if you notice a rash or pain on your scalp.
If your daily hair fall is more than the usual 80-100 strands of hair, you might be suffering from stress-related hair loss. If you notice bald patches on your scalp, it may be a sign of Alopecia Areata. If you have had the urge to pull out your hair, it may be stress-induced Trichotillomania.
After hair stops shedding, the hair will slowly grow back. This can take 6 to 8 months for all the hair to grow back. The whole cycle takes about 12 months. This type of hair loss is called telogen effluvium.
Ways to Stop Alopecia Areata from Spreading or Worsening
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
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.
Type 2 diabetes was associated with an increased risk of severe central scalp hair loss in AA women. Patients with type 2 diabetes should be followed closely for central scalp hair loss so that appropriate treatment can be offered.
The first sign of alopecia areata is often a round or oval bald patch on the scalp.
New patches may spread by joining existing bald patches. These larger bald areas can appear while hair is regrowing in older hairless patches. Loss of hair can be permanent in some cases. Hair follicles may deteriorate, but oil producing glands in the skin (sebaceous glands) usually change very little.
Ketoconazole shampoos help treat Alopecia by cleaning the skin area around your hair follicle of sebum, or the skins natural oils that are produced. Getting rid of these oils can allow your hair follicles to receive more nutrition and release for your hair to regrow.
Although infrequent, alopecia can be caused by benign cutaneous tumours.
