Hair loss can be very distressing for both men and women. Especially if hair loss is beyond control and no remedy seems to be working. There can be many symptoms of hair loss but the most common is hair thinning and hair loss at the crown. It is true that men are more likely to lose hair than women primarily because of male pattern baldness. But even females experience hair loss in the form of extensive hair loss at the crown area.

What Is Androgenetic Alopecia?

Androgenetic Alopecia is a term used to describe patterned hair loss in both men and women. In men, androgenetic alopecia is also known as Male Pattern Baldness and hair loss begins as early as in their 20s. In women, this condition is known as Female Pattern Baldness and they usually don’t experience hair thinning until they reach their 40s.

Around two-thirds of men around the world are affected by male pattern baldness. Although hair loss starts in their 20s, 40% of males tend to experience considerable hair loss by the age of 35. What starts as receding hairlines initially leads to partial or complete baldness if left untreated.

On the other hand, androgenetic alopecia in women is not noticeable until their 40s or later. Around one-third of women experience female pattern androgenetic alopecia at some time in their lives. Women generally experience extensive hair thinning and widening of hair partitions.

What Causes Androgenetic Alopecia?

Androgenetic alopecia is caused due to an increase in the androgen levels in the body. Androgen is a male hormone found in men and in small quantities in women. The increase in the levels of androgen increases the sensitivity of hair follicles making them shed hair faster than normal.

Although an increase in androgen levels is the principal cause behind androgenetic alopecia in females as well as males, yet there are other factors leading to the same –

Androgenetic Alopecia In Females –

PCOS Or Ovarian Conditions – Certain ovarian conditions such as cysts or Poly Cystic Ovarian Syndrome (PCOS) are linked to higher levels of androgens. Women with these conditions are at a higher risk of developing androgenetic alopecia.

Oral Contraceptives – Some oral contraceptive or birth control pills are highly androgenic and trigger hair loss in women.

Hair Supplements – In some cases, iron deficiency may be the cause of hair loss or the deficiency of other vitamins and minerals. Especially, in pregnant or anaemic women, iron supplements may prove beneficial.

Other Alternatives – Good quality hair pieces or wigs may be the best option to cover the bald areas.

Alopecia Areata Vs Androgenetic Alopecia

Androgenetic alopecia is a genetic male pattern baldness whereas alopecia areata is an autoimmune disorder where hair loss is experienced in round patches. Androgenetic alopecia is known to affect about 50% of men in the age of 50 or above. Alopecia areata affects 1.7% of the world. Both the conditions require a different line of treatments.

Telogen Effluvium Or Androgenetic Alopecia?

Telogen effluvium is a form of hair loss which occurs due to larger amount of hair cycling into the telogen or resting phase. In this stage, hair is ready to fall out eventually leading to excessive hair loss. The hair loss can be caused by pregnancy, stress, certain medications or surgery. This type of alopecia usually gets resolved on its own after several months, unlike androgenetic alopecia which requires proper treatment.

Is Baldness Inherited From Mother Or Father?

The primary baldness gene is on X chromosome which men only get from their mothers so the hereditary factors indicate that it is more dominant on the mother’s side. But in some cases, it has been found that men tend to develop male pattern baldness if they have bald fathers.

Is Androgenetic Alopecia Genetic?

Androgenetic alopecia will not always be due to genetic reasons as various environmental factors are also responsible for the same. However, having a relative with this condition puts you at a higher risk.

Is Androgenetic Alopecia A Disease Or A Disorder?

Androgenetic alopecia is a disorder that affects both men and women. What causes androgenetic alopecia is genetically determined yet the inheritance pattern is still unclear.
