Why is my hair thinning?

hair loss

by Lorna White |

Did you know that it's normal to lose 50 to 100 hairs per day? But if you're losing any more than that, it could mean your hair is starting to look on the thinner side.

Thinning hair doesn't always mean you have bald patches, but it's likely that overall your hair may look sparse in areas.

As hair thins over time over a very gradual period, you might not notice these changes straight away, so it can be hard to pinpoint exactly what is causing the thinning.

If you've noticed your hair is looking a little thin and you want to try and do something about it, we've rounded up everything to help you learn why your hair is thinning, from the causes, remedies and when it might be something to worry about.

What causes thinning hair?

Everyone's hair is different, and your hair type can depend on a number of things including your genetics, diet, lifestyle choices plus how you style your hair. Different medications and medical conditions can also cause thinning of the hair.

Other causes include:

• Over colouring or perming your hair

• Harsh hairsprays or gels

• Stress

• Lack of iron in your diet

• Regularly wearing tight hairstyles

• Lack of vitamin D

• Recently had a baby

• Recently stopped hormonal contraception

• Skin disorders

• Experiencing hormonal changes

• Losing a significant amount on weight in a short period

How can thinning hair be treated?

If you're concerned about thinning hair, it's worth talking to your doctor before trying any treatments or remedies. Your doctor will also be able to rule out any other underlying cause of your thin hair.

Thickening hair shampoo

There are many thickening shampoos and conditioners available on the market. They work to add volume to the hair to help it appear thicker. Many also contain vitamins to help improve your scalp health, which may lead to more hair growth. In some cases, you might be prescribed a prescription strength thickening hair shampoo.

Vitamins and supplements

If you struggle to have a balanced diet, it might be worth getting some multivitamins. It might even be worth asking your doctor for a blood test if you think you might have a deficiency.

A daily multivitamin supplement might be a good place to start, but there are extra vitamins and supplements you can buy that support hair growth including:

• Folic acid - great for generating cells

• Vitamin B7 - also known as biotin

• Omega 3 and 6 - great for your skin and fighting inflammation

Scalp massages

Giving yourself a scalp massage can be very relaxing and it won't cost you a penny. It's a nice thing to do when washing your hair in the shower or bath. Apply some pressure to your scalp with your fingertips while you're washing with shampoo, and this will help encourage blood flow around the scalp. You could also use a massage tool if you prefer.

Essential oils

Although the evidence to back the effectiveness of essential oils when it comes to hair loss, some swear by lavender oil or rosemary or thyme oil. Just make sure you dilute them and do a patch test before applying to your scalp.


There are medicated options you can buy for hair loss if the other options aren't working for you.

• Minoxidil -also known as Rogaine, it's an over-the-counter hair loss treatment that's applied to the scalp

• Spironolactone - this might be recommended if your hair loss is down to hormonal reasons

• Finasteride - a pill that men could be prescribed
