4 reasons why your hair is thinning

It is certainly normal to lose some hair daily, however, there are a number of reasons why your hair may be thinning. Here are the main four reasons to explain why.
1. Iron deficiency anaemia
Being low or deficient in iron can lead to hair loss. Symptoms of iron deficiency anaemia can include fatigue, weakness and pale skin. You may also notice headaches, difficulty concentrating, cold hands and feet and as mentioned hair loss. Iron deficiency essentially sends your body into survival mode, so your body channels oxygen to support vital functions as opposed to what it deems non-vital – like keeping your hair intact. The best way to check your iron status is to see your GP for an iron studies test.
2. Hypothyroidism
Hypothyroidism is a condition in which the body lacks sufficient thyroid hormones; it can result in a host of symptoms including unexplained weight gain, fatigue, constipation, depression and difficulty concentrating. Hair, nails and skin may become more brittle and break more easily, and hair loss is also common.
3. Omega-3 fatty acids
In order to have healthy hair and avoid hair loss, we need to make sure that we are getting enough of the right nutrients in our diets, including omega-3 fatty acids. Adding more of these fatty acids to your diet can help to prevent hair loss and even encourage hair to grow healthier. Omega-3 fatty acids have anti-inflammatory properties, which can help to open the hair follicles, promoting healthy hair growth. When the body is not receiving sufficient nutrients, the hairs that are lost regularly each day are less likely to be replaced, and hair loss is more likely.
4. Vitamin D
Low vitamin D levels interfere with healthy hair follicles regenerating. Again, this can be assessed via a blood test.
There can also be physical reasons such as excessive styling, straightening and dying, which can lead to hair loss. Heat and some chemicals can weaken the hair, causing it to break and fall out. If your hair loss is consistent it's best to seek individualised advice from a health professional.
