Medical information on thinning hair in men
Thinning hair is something that affects many different people and can be caused by many different things. The good news is that, in some cases, thinning hair may only be temporary and could resolve itself within a few months. In other cases, thinning hair may be caused by a long-term condition which may or may not be treatable.
Why is my hair thinning?
In many cases, thinning hair does not have to be a cause for concern. This is because it is a natural part of the ageing process later in life. It is also something that can happen due to illness, stress, hormonal changes or certain medications. In the case of the former, hair loss is to be expected and should therefore not cause too much alarm when it begins to happen. In the case of the latter, the thinning of your hair is likely to be temporary.
For other people, however, thinning hair or patchy hair loss may require medical attention.
Causes of thinning hair
Male pattern baldness
If you are a man experiencing hair loss in the form of a receding hairline and thinning on the crown of the head, it is likely that you are suffering from male pattern baldness. This is the most common type of hair loss (affecting approximately half of all men over 50). It is recognisable as, typically, it only affects the crown and front of the head (above the temples). There is no cure for thinning hair caused by male pattern baldness but there are successful treatments. For more information on successful prescription treatments, visit our online hair loss clinic.
Female pattern baldness
If you are a woman experiencing thinning hair on the top of the head, it may be that you are suffering from female pattern baldness. This type of hair loss cannot be treated using finasteride (used for male pattern baldness). However, it can be treated using minoxidil, a foam or lotion rubbed into the scalp once or twice a day.
Some people may not find that their hair is thinning, but that it is falling out in patches. This type of hair loss is called alopecia areata, a condition caused by problems in your immune system. The good news is that this type of hair loss often resolves itself within a few months, leading to regrowth. In other cases, it leads to more severe forms of hair loss which cannot be reversed. Alopecia areata can be treated with minoxidil, light therapy and corticosteroids, amongst other treatments.
In some cases, thinning hair can be caused by hormonal changes, stress, illness, changes in your diet or certain medications. This is known as telogen effluvium and is characterised by slight - and temporary - hair loss on the head. A more serious version is known as anagen effluvium, in which there is widespread hair loss across the body. This is commonly caused by chemotherapy and radiotherapy and usually stops after treatment has ceased.
Treatments for thinning hair
The most effective treatment for thinning hair caused by male pattern baldness, is finasteride. Finasteride works by disrupting the effects of the male hormone DHT upon the hair follicles. In one study, 90% of the men who took a tablet containing 1mg of finasteride every day for 6 months experienced the halting of hair loss. You can learn more about the generic version of finasteride here.
Another treatment for thinning hair is minoxidil. This is a medicine available over the counter in pharmacies. It can be used to treat male pattern baldness, female pattern baldness and alopecia areata. It is clinically effective in 60% of men, and can lead to the halting of hair loss and regrowth when used correctly. Minoxidil comes as a foam or lotion and must be rubbed into the scalp once or twice a day for around four months before effects are seen. Like finasteride, hair loss will resume after treatment with minoxidil has ceased.
Hair loss shampoos
Many brands of hair loss shampoo are available in high street pharmacies, but there is little evidence to suggest that they actually work. These sorts of products may improve the overall health of your hair, but are unlikely to affect how it grows.
In the case of alopecia areata, there are many treatments available. These include injections of corticosteroids, topical corticosteroids, immunotherapy and light therapy. These will vary in effectiveness and - as with finasteride and minoxidil - are treatments not cures.
If you’re a man currently suffering from male pattern baldness, you may be able to effectively treat your thinning hair by using prescription treatments. Visit our online clinic to learn more.
