Hi There,
I got loads of white hair growing and I first of all thought it was to do with ageing, there was so many so soon that crept out of nowhere and i was getting more by the day, it didn't add up, i've red hair and didn't have one grey hair, then i found out through chance because my hair was falling out in handfulls and looked dead and my overall hair colour looked more like a mousey light brown colour with a tinge of red and i was so sick, i changed my doctor because the other one was never any help to me, the first thing my new doctor did was send for blood tests and gave me an overall health check and my blood came back that my iron level was dangerously low, i started my iron and within 3 months of taking it, the white hairs are dissapearing and my red hair coming through, i read afterwards that the ferritin in the hair is the last to go when the stores are used up in the liver, it makes sense to me now and a doctor at hospital backed it up too, i hope this is of some help to you, its worth getting her blood checked out anyway.
Elaine :)
