Hair loss

Hair loss

At any given time, 10 to 20 percent of the hair follicles on the head are in a resting phase where they are not producing hair. On average, it is normal to lose between 50 and 100 head hairs per day. In the case of hereditary hair loss, illness, poor nutrition or a stressful life situation, the normal daily hair loss can increase considerably.

Hormonal hair loss

Hormonal hair loss is most common in men and in women after menopause. This type of hair loss can be caused by elevated concentrations of a type of testosterone in the scalp (Dihydrotestosterone - DHT). DHT can settle in the scalp and hair follicles, and this can disrupt the normal growth phase that is important for healthy hair and natural hair growth.

Hereditary hair loss

Hereditary hair loss can come from both the mother's and father's side, and affect both men and women. Hair loss in men is often more concentrated on the top of the head and in the temples, partly because more DHT is seen in these areas. In women, hair loss is usually more diffuse and more evenly distributed over the entire head. Many women also experience this type of hair loss, especially after pregnancy and after menopause.

Physical and psychological stress and hair loss

A high level of stress can also lead to hair loss. This type of hair loss is usually not permanent. When the stress is reduced, the hair follicles begin to produce hair again through a natural growth phase. It is still important to use good hair care products.

Increased hair loss due to increased sweating on the scalp?As mentioned, increased occurrence of DHT in the scalp can lead to thinning hair and hair loss. As the enzyme involved in the formation of DHT in the scalp is also produced in the sweat glands in the scalp, some studies have shown that there may thus be a possible connection between increased sweating in the scalp and increased hair loss. The theory is based, among other things, on the fact that exercise and sweating, as well as the use of helmets and headgear, which can also lead to increased sweat production in the scalp, can have an impact on the production of DHT and thus also hair loss.

Hair loss during pregnancy and breastfeeding

There are several changes that occur in a woman's body during pregnancy. Physical and psychological stress in connection with childbirth as well as hormonal changes can both lead to hair loss after childbirth. This condition is temporary and most women begin to regrow their hair within 6 to 12 months after giving birth.
