Understanding Hair Loss and Hair Thinning in Men Causes Treatment

Many people experience changes to their hair at some point during their lives. While women also struggle with thinning hair and hair loss, men outnumber women in this category: 70% of men struggle with hair loss in comparison to 40% of women.

With such a high percentage, even if you’re not struggling with hair loss or thinning yourself it’s highly likely you know someone who is. However, the causes differ from person to person. Your lifestyle choices, environment, hormone related conditions , thyroid disease and genetics can all contribute to a reduction in hair coverage, and your experience of hair thinning or loss could differ from your best friend’s, or even your father’s1.

Many men affected by hair thinning will suffer emotionally, with their confidence being affected and even dealing with anxiety, depression, or insecurity. A survey commissioned by Nioxin has found that over half the men were in denial about their hair loss, refusing to talk to anybody about the problem.

What Causes Hair Thinning Or Hair Loss In Men?

Many causes of hair loss and hair thinning are due to the interruption of the hair growth cycle, which has three phases – anagen (growth phase), catagen (transitional phase) and telogen (resting phase). Hair normally sheds at the end of the telogen phase as a new hair pushes through, but a disrupted cycle could mean that hair sheds before new growth is fully ready2.

Genetics, underlying medical conditions, or environmental causes like stress and unhealthy lifestyle choices could all be reasons for hair thinning, and in some cases progressing to a partial loss of hair (e.g. a receding hairline) or even total loss of hair.

Genetics is one of the main reasons for hair loss in men. If you have a family history of hair loss, it is possible that you will experience it too, and that fact holds true for both males and females. However, there are other reasons our hair thins or falls out, some of which we can control. Other causes include:

Hormonal changes especially increase in dihydrotestosterone (DHT), the male sex hormone. DHT affects the hair follicles, making them produce smaller and shorter in length, until shrinking completely and not producing any more hairs3. Some hormonal changes may be age-related.

Extreme dieting and malnutrition – hair grows from inside the body, so if the body is not supplying the correct nutrients hair growth may be substandard.

Medical and genetic conditions such as alopecia and male pattern baldness

Medications and treatment used for diseases like arthritis and heart problems, and radiation for cancer patients

Environmental factors such as polluted air or water


Damage to the hair follicles through excessive straining (as with certain hairstyles) or harsh chemical treatments
