Edit Common causes of men's hair loss

<p><strong>Acute/chronic telogen effluvium:</strong> In our <a title="Hair: What is it and how does it grow?" href="/blog/597/hair:-what-is-it-and-how-does-it-grow">first blog</a> we discussed the stages of the hair growth cycle. In this condition, a sudden change in our physical or psychological health drives hair follicles into the telogen phase.</p> <p>This results in more hairs falling out than growing and gives rise to generalised hair loss over the entire scalp with no specific pattern.</p> <p>In the acute form of the condition, this shedding occurs over six months and often resolves on its own. However, if the hair loss is sustained this is described as chronic telogen effluvium.</p> <p><strong>Alopecia areata:</strong> Patients develop small bald patches in their hair which occurs as a result of the body’s immune system overreacting to its own hair follicles.</p> <p>They then become thin, discoloured and fall out. Given time they will often grow back without the need for treatment. In rare cases, the hair loss may develop into a loss of all scalp hair (alopecia totalis) or the entire body (alopecia Universalis).</p>
