Suffering from hair loss? Causes and Prevention

Hair Loss: Causes and Prevention

Hair loss affects many men and although not harmful, it can have a considerable impact on someone's self-esteem. Hair loss can have various causes. However, in more than 90% of cases, the cause of hair loss lies in genetic factors and the effect of DHT.

Genetic Factors

One of the most common causes of hair loss is genetic predisposition. Androgenetic alopecia, better known as male pattern baldness or male hereditary baldness, affects many men. This type of hair loss is characterised by a predictable pattern and is largely due to genetics and DHT.

Dihydrotestosterone (DHT) and its effect on hair loss

DHT is an androgen, a type of sex hormone that has a major influence on hair growth. While DHT is essential for certain male characteristics, it also plays a crucial role in androgenetic alopecia, or male pattern baldness.

DHT binds to receptors in hair follicles, especially in areas that are prone to hair loss, such as the hairline and crown. This can lead to a process called miniaturization, where hair follicles shrink and eventually stop producing healthy hair. This process not only reduces the size of the hair follicle but also shortens the growth phase of the hair, resulting in thinning hair and ultimately hair loss. Interestingly, while DHT contributes to scalp hair loss, it can help promote hair growth on other parts of the body, such as the beard and chest.

Nutrition and stress have an impact on your hair growth

A lack of essential nutrients can contribute to hair loss. Iron, protein, and vitamins such as vitamin D and vitamin B12 are essential for healthy hair growth. A balanced diet rich in these nutrients can help prevent hair loss.

Both physical and emotional stress can cause a temporary form of hair loss known as telogen effluvium. Managing stress through techniques such as meditation, regular exercise, and adequate rest can help reduce hair loss.

Treatment options focused on genetic and hormonal causes

Finasteride

Finasteride is particularly effective because it inhibits the action of 5-alpha reductase, which blocks the conversion of testosterone to DHT. This lowers DHT levels in the scalp and slows the hair loss process. By reducing DHT production, finasteride can reverse or slow the progression of hair loss and, in some cases, stimulate new hair growth. Research shows that in 94% of cases, hair loss stops and hair grows back in 66% of cases. Finasteride works better in men than women and is available by prescription.

Minoxidil

Minoxidil works in a different way than finasteride and has no influence on the hormonal causes of hair loss. Instead, it works by improving blood flow to hair follicles, which can help strengthen them and stimulate hair growth. For example, it can strengthen hair affected by DHT and extend the lifespan. Minoxidil is a topical treatment suitable for both men and women.

Understanding the complex interaction between hormones such as DHT in relation to hair loss offers valuable insights into how treatments such as finasteride and minoxidil can help. With the right approach and treatment, it is possible to minimize the effects of hair loss and, in many cases, improve your hair growth.
