Ask an Expert: Why Is My Hair Suddenly Falling Out?

“There are a number of reasons for hair loss,” says Dr Kim Glass, lead GP at Bupa Health Clinics. “It’s not uncommon for your hair to thin with age. Although you can’t stop it, you can delay the process by maintaining a healthy diet and having a health check to make sure there are no underlying causes for your hair loss. If you’re worried about it relating to your physical or mental health, speak to your GP.

“Low iron and low thyroid levels can also cause your hair to become thinner and fall out more than usual. A blood test will identify if you have low iron or thyroid levels, and both of these can be increased through taking tablets. The hair loss should recover completely, although this may take a few months.

“The most common form of alopecia in women is female pattern hair loss, also known as androgenetic alopecia. It’s a genetic condition and people with it will notice hair loss on the top of their heads. It usually occurs in your fifties or sixties, much like male pattern hair loss in men. If you have female pattern hair loss your GP may suggest you try a minoxidil 5% solution, which is a topical lotion or foam that’s available over the counter. It’s not guaranteed, but it can promote regrowth, at least in the short term for some women. If this doesn’t work, you may be referred to a dermatologist for further tests.

“Look out for inflammatory scalp conditions; skin conditions such as psoriasis, eczema or an infection can cause your hair to fall out. Often this can be treated, however, if the condition is severe, it may kill your hair follicles resulting in permanent hair loss. There are a few treatments that can be tried, such as topical corticosteroid creams or steroid injections, but the earlier you can see a doctor, the better.

“Finally, using straightening chemicals and hot combs can damage your hair. It sounds like a simple thing, but also avoid wearing your hair too tight, as you may be pulling out some of your hairs.”

“In cases of hereditary hair loss, sadly prevention isn’t an option as it’s completely natural,” says Dr Patel. “The treatment here will either involve paying for a hair transplant or hairpiece which can be expensive, or counselling to help you come to terms with the loss of your hair.

“If you’re suffering from alopecia, a doctor can suggest various treatment such as steroids, immunotherapy or light treatment to encourage growth, but they aren’t without side-effects. However, it’s important to remember that your hair loss may only be temporary and so might come back without any treatment being required at all.”
