Types of alopecia: understanding the different variants

Alopecia is a disorder characterized by hair loss in patches or in its entirety. Men, women, and children of any age can be affected by this condition, and it can often be the result of an autoimmune problem. Alopecia is a hair disorder that comes in many forms, each with its own set of symptoms and treatments.

female pattern baldness

It is the most common form of hair loss in women. This is due to hair follicles, tiny holes in the skin that contain each hair. Baldness occurs because the hair follicle gradually shrinks over time, producing thinner and shorter hair. When the follicle stops producing hair, the hair is still alive, suggesting that there is still a chance for it to produce new hair.

There are certain possible causes for female pattern baldness, although the exact reason is still unknown. Among them we can mention:

  • the aging
  • Changes in androgen levels. These hormones have a stimulating effect that can affect many aspects of physical and aesthetic development.
  • Baldness caused by heredity, often manifesting itself through male or female pattern baldness. Knowing the family history of baldness can give an indication of the transmission of the gene to future generations.
  • Heavy menstrual bleeding during your period.
  • Medicines that contain estrogen, such as oral contraceptives.

male pattern baldness

It is the most common type of hair loss in men. It affects the vast majority of men and can cause severe hair loss or complete baldness over time.


Male pattern baldness is genetic and is related to male hormones. It usually starts with a receding hairline and tapering at the top of the head.

air alopecia

Alopecia areata is a medical condition that results in patchy hair loss and is usually seen as circular bald patches on the scalp or facial hair. Alopecia areata is identifiable from other types of alopecia as it does not cause inflammation, redness, scaling or other abnormalities. The affected area is normal in appearance and can affect both sexes and at any age, although more cases are reported in adolescent males.

Different types of alopecia can be confused with alopecia areata, such as trichotillomania, tinea capitis, loose anagen hair syndrome, syphilis-induced alopecia, and tick-induced alopecia. It is important to identify and differentiate these types.

Drugs that can cause alopecia

Hair loss can be a side effect of certain medications or drugs. The chemicals in these medications act on the hair follicles during the anagen stage, causing the hair to thin or fall out within days of consumption.

Certain medications such as vitamin A, chemotherapy drugs, antithyroid drugs, mercury, and high dose valproic acid are known to cause hair loss or alopecia. Clinical studies have confirmed that once the use of a certain drug is stopped, hair loss ceases. Generally, drug-induced alopecia resolves within 2 to 3 months after stopping the drug.

Different drugs can have an adverse effect on hair health. Some of these include ACE inhibitors, anticoagulants, antifungals, antineoplastics, antiparkinsonians, anticonvulsants, beta blockers, oral contraceptives, H2 antihistamines, pesticides and retinoids.

It is always recommended to consult your doctor about the possible side effects of any medication he prescribes. This is a way to better protect yourself from unforeseen health risks.
