A menopausa causa queda de cabelo?

GP Dr Aarti Narayan Denning, who specialises in cosmetic medicine, points out that hair loss during the menopause and perimenopause is more common than you might think.

"Most women experience overall hair thinning rather than noticeable bald spots. The thinning can occur on the front, sides, or top of the head. Hair may also fall out in large clumps during brushing and showering," she points out.

"It's estimated that around 70% of women over the age of 70 experience hair loss," she adds.

Nevertheless, such a change in your appearance can be understandably distressing.

Why menopause affects your hair

Why might the menopause affect your hair? The answer, of course, is hormones. Lack of oestrogen could lead to a lacklustre mane.

"Hair loss during menopause is the result of lowered production of oestrogen and progesterone. These hormones help hair grow faster and stay on the head for longer periods of time. When the levels of oestrogen and progesterone drop, hair grows more slowly and becomes much thinner," Denning explains.

The majority of us can relate to the lack of confidence associated with a 'bad hair day'. And many women find that menopause-associated hair loss damages their confidence.

"We live in an age of easy image sharing and broadcasting, with the side-effect that our appearance is exposed to judgement. Even though hair loss is not life-threatening and considered cosmetic in many cases, the effects on patients' quality of life are real," says Denning.

And the research backs this up. While both men and women are affected by hair loss, the impact may be more devastating in women, sometimes leading to social self-exclusion and severe depressão.

But if you've become unhappy with your hair since the menopause, you're not alone. More comforting still, there's plenty that can be done.

Denning advises that you speak with your GP early - as soon as you notice a change in your hair - so that a possible cause can be identified. You might have a nutritional deficiency, for instance, that can easily be remedied with the right supplement.

She explains that your doctor will want to take a full medical history.

"I look at a woman's stress levels, changes in hormone treatment, chronic illness, life stage changes. And of course, examining the hair to look for any physical changes."

Your GP might call for some exames de sangue, to check for healthy levels of iron and various vitamins, along with your thyroid and other hormones.

If the blood tests come back normal, hair loss treatment minoxidil is sometimes prescribed, which many women find helpful - although this is highly unlikely to be available on the NHS. But don't rule out non-medical intervention, says Denning. Never underestimate how much your hair will thank you for avoiding aggressive styling, irritating chemicals and heat treatments. "Sometimes the simplest approach is the best."

If hair changes during the menopause are associated with other uncomfortable symptoms such as skin changes, hot flushes, and mood swings, terapia de reposição hormonal (TRH) may be worth looking into. But always ask your GP whether it's appropriate for you.

"We need to take into consideration the many different factors affecting hair growth, hair fall and hair distribution first," cautions Denning. "But the good news is that when hair loss is part of normal hormonal changes and ageing, it is treatable."

However, it's important to bear in mind that the risks and benefits of HRT must be carefully assessed before planning treatment.
