It's normal to shed hair. We can lose between 50 and 100 hairs a day, often without noticing.
If you lose more hair than normal you may have alopecia - the medical name for hair loss.
Losing your hair is not usually a sign of illness, but it can be upsetting.
Symptoms
You may notice:
- your hair sheds more when you brush or wash your hair
- hair not growing, resulting in bald patches on your scalp
Some types of hair loss may last for a short while. But other types are lasting, like male and female pattern baldness.
Where you can lose hair from
You will usually lose hair from your head. You can also lose hair from other parts of your body, for example your eyebrows and legs. Loss of hair on your legs as you get older is common.
Who can have hair loss problems
Adults, children and babies can have hair loss or hair growth problems.
Some hair loss is a normal part of getting older. Your hair thins and you shed more hair.
Some babies are very slow to grow hair. But it usually does not continue into childhood.
Types of hair loss (alopecia)
There are many types of hair loss with different causes.
Common types of hair loss are:
Alopecia areata
If you have alopecia areata you get patches of hair loss on your scalp. Your hair usually grows back.
Telogen effluvium
If you have telogen effluvium your hair sheds and gets thin. For example, after having a baby or period of illness.
Some of the causes are:
- an illness
- stress
- weight loss
- iron deficiency
Your hair stops shedding or grows back after a few months - usually once you are better.
Frontal fibrosing alopecia
Frontal fibrosing alopecia is where you lose your eyebrows and notice your hairline receding. It's more common in women.
Male pattern hair loss
Male pattern hair loss hair is when you lose hair from the crown of your head. It often runs in families and some people lose their hair at a young age.
Female pattern hair loss
Female pattern hair loss is when you have thinning of hair on the crown of your head. This can run in families. It is not connected to your age or to menopause.
Hair loss from cancer treatment
Hair loss from cancer treatment can affect people in different ways. Some treatments cause you to lose only some hair or for your hair to thin. But some cause you to lose hair from all over your body.
Treatment
Most hair loss doesn't need treatment and is either:
- for a short time and it will grow back
- a normal part of getting older
Non-urgent advice: See a GP if you:
- have areas of hair loss that are itchy or sore
- are losing hair in clumps
- are worried about your hair loss
- have sudden hair loss
Hair loss treatments
Treatment may help with some types of hair loss. But no treatment is 100% effective.
Treatments include:
- steroid injections given into bald patches
- steroid creams you put on bald patches
- a tattoo used to look like short hair and eyebrows
- hair transplant - hair cells are moved to thinning patches
- scalp reduction surgery - sections of scalp with hair are stretched and stitched together
- artificial hair transplant - surgery to implant artificial hairs
There are no active clinical trials for hair loss at the moment.
Hair clinics
If you are thinking of going to a commercial hair clinic talk to your GP before doing this. These can be expensive.
Cost of medicine
Your GP can tell you if any medicines are covered by your medical card or under the drugs payment scheme.
Shampoo
There is no shampoo that will help your hair regrow. Use mild shampoo if you have hair loss - ask your pharmacist about shampoos you can buy.
Supplements
There is not enough evidence that vitamins and supplements work for hair loss.
Wigs and hair replacement products
If you have hair loss you may choose to wear a hairpiece, wig or hair replacement. These are usually made with synthetic materials or real hair.
Talk to your specialist doctor, care team or GP. They can prescribe these products and give you details of suppliers in your area.
Talk to them or a hair replacement specialist about the different types of hair replacement products and the costs involved.
Help for hair replacement costs
You may be able to get help with the cost of a hairpiece, wig or hair replacement.
You can get help to pay for these products through:
- the HSE, if your hair loss was caused by your cancer treatment
- you or your partner’s PRSI contributions (the government's Treatment Benefit Scheme)
- your medical card, if you do not qualify for the Treatment Benefit Scheme
- your private health insurance - contact your insurer to check
