There are different types of hair loss. The way in which hair loss occurs also differs between men, women and children. The most common cause of hair loss in both men and women is hereditary hair loss: androgenic alopecia (androgenetic alopecia).

Hair loss is a disorder caused by an interruption in the body’s cycle of hair production. Hair loss can occur anywhere on the body, but most commonly affects the scalp. On average, the scalp has 100,000 hairs that cycle through periods of growing, resting, falling out, and regenerating.


Hair growth cycle Hair Science Clinic


Most people lose 50 to 100 hairs per day as part of this natural cycle. If the cycle of hair growth is disrupted or if a hair follicle is damaged, hair may begin to fall out more quickly. This causes symptoms such as a receding hairline, hair falling out in patches or overall thinning of hair.

Hereditary hair loss

A normal hair growth cycle, which lasts 2-5 years , consists of three phases; first an active hair growth phase, then a resting phase and finally the hair falls out. Excessive natural hair loss occurs when the growth phase is shortened. Hair loss may be linked to many medical and behavioral conditions but genetics are the most common cause for natural hair loss in both men and women. DHT is often the disruptor and main cause of hereditary hair loss.


DHT and hair loss Hair Science Clinic



Male hormones, DHT in particular, cling to receptors on the hair follicles. This causes a shortening of the anagen (growth) phase. Big hair follicles gradually become smaller. The follicles survive the hormonal attack their ability to produce hair is affected. Hair becomes smaller and shorter with every cycle. This so called miniaturization of hair is typical. At the end of every cycle the hair is thinner. 

Patterns of baldness

Allthough a male hormone (DHT) is the main cause, both men and women can suffer from hereditary hair loss. 


Male pattern of hair loss

In men, hair loss can begin any time after puberty and progress over the course of years or decades. It starts above the temples and continues around the perimeter and the top of the head, often leaving a ring of hair along the bottom of the scalp.

Female pattern of hair loss

In women, hair slowly thins all over the scalp, but the hairline usually doesn’t recede. Many women experience this type of hair loss as a natural part of aging, although hair loss may begin any time after puberty. Female pattern hair loss can cause hair to thin dramatically, but only rarely does it lead to baldness.

Genetic cause

Androgenetic alopecia is in fact not a disease or hair condition, but an age symptom that is mainly genetically determined. Scientists have discovered genetic variation in the androgen receptor, but not all responsible genes have been identified yet.



Having to deal with hair loss and baldness at a young age is confrontational. Especially for young men and women suffering from visible hair loss. Losing your hair or becoming bald can be a burden. It can have huge impact on one´s life quality.


Get a professional diagnosis

Hereditary hair loss can easily be diagnosed by a professional, because the pattern is predictable. If heredity is not the cause, hair loss can have many other causes, for example a hair disease, hormones, cosmetics and several other factors. That is why an examination by a physician and a correct diagnosis should always be the starting point for any form of treatment.

Alopecia Areata

Alopecia areata is a condition that causes hair to fall out in small patches. The condition develops when the immune system attacks the hair follicles, resulting in hair loss. Sudden hair loss may occur on the scalp, but also eyebrows, eyelashes, face, as well as other parts of the body can be affected. The condition can result in total hair loss, this is called alopecia universalis.

Alopecia in beard


Alopecia areata is an autoimmune condition. It´s prognosis is different for each person. It can be emotionally challenging, patients often feel isolated and insecure. The hair loss associated with alopecia areata is unpredictable and appears to be spontaneous. Family predisposition plays a role, as well as stress.

Hair loss – is it temporary or permanent?

Hair loss and baldness caused by diseases, medical procedures, stress and use of medication is often temporary. The hair growth process usually restarts after finishing medical treatment and recovery. Hereditary hair loss however is permanent. It´s irriversible: hair that is gone is gone forever.
