Why Lack of B12 Causes Hair loss and Greying
A new hair grows when the hair cells divide and multiply, pushing the hair out and above the skin surface. You can imagine building hair with a Lego, only thing is that you are building from below.
When the levels of B12 are low, the hair cells can’t divide as efficiently. This causes the hair growth to slow down a lot or in few cases even stop completely.
Also, a lack of B12 affects the overall health, and if you are poorly your hair will not thrive, it will suffer too.
The good news is that once Vitamin B 12 levels are restored, hair cells will be able to grow and replicate properly. And your lost hair will come back in a few months time.
Your body needs B12 for:
- making of red blood cells – which delivers oxygen to every cell in our body (including hair cell)
- healthy brain and nervous system function
- cell formation and longevity
- food digestion, absorption and iron use
- fat and protein metabolism (fat and protein molecules are broken down to create energy)
- healthy immune system function
- mood regulation, and reduce incidence of depression and anxiety
- memory function, concentration and mental clarity
