    Thinning hair in men is common 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.

    What is thinning hair?

    Thinning hair is the process by which your hair gets thinner. This might be in patches, from the hair line or along the crown. 

    Why is my hair thinning?

    Other than ageing, thinning hair is also something that can happen due to illness, stress, hormonal changes or certain medications. In this case the thinning of your hair is likely to be temporary.

    For other people, however, thinning hair or patchy hair loss may require medical attention.

    Is thinning hair normal with age?

    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.  Hair loss is to be expected and should therefore not cause too much alarm when it begins to happen.

    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 typically affects the crown (top of head) 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.

    Alopecia areata

    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, and is a so called "auto immune condition"; it can also be caused or triggered by stress, but often we don't know why it happens. 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.

    Telogen effluvium

    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.

    Will hair loss caused by stress grow back?

    As explained above telogen effluvium, the loss of hair due to stress, illness, changes to diet or hormones, is likely to be temporary and the hair will grow back. Even the more serious anagen effluvium, which causes hair loss across the body (often caused by cancer treatments) will usually stop once treatment has come to an end. 

    Can thinning hair be restored?

    For some men thinning hair might be temporary and hair could come back within a few months. For others, thinning hair may be long-term, and you may or may not be able to treat. 

    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 and online. 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.

    Products for thinning hair 

    Hair loss shampoos

    Many brands of hair loss shampoo are available in high street pharmacies (or you can buy DHT blocking shampoo from our service), 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.

    Supplements for thinning hair 

    Hair loss vitamins are nutritional supplements. They aim to improve the quality of hair and treat male pattern baldness. If you think a vitamin deficiency is the cause of your hair loss, taking a supplement may be effective.

    Other treatments

    In the case of alopecia areata, the treatment options are different. 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.

    We offer a bundle of non-prescription hair loss treatments, which might help support hair health, and treat hair loss for some men.  

    What is the best treatment for thinning hair?

    The most effective treatment for hair loss for men is Finasteride or branded Propecia. These treatments are not suitable for women. 

    Depending on your hair loss, you might find that minoxidil shampoo, such as Regaine, will help manage your thinning hair. You can get both male and female versions of the shampoo so this might be a good option for women who can’t take Finasteride/Propecia.  

    Hair thinning treatment for females

    Other than Regaine for Women, unfortunately, there aren’t any treatment options for women experiencing hair loss. Wigs, steroid injections or hair transplants might be options for some.

    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. Alternatively, you will find plenty of hair loss advice in the advice hub.
