I was in the bathroom with 2 mirrors looking at the back of my hair. I noticed the back of my hair at the neck is uneven.
Is hair at the back of the neck supposed to be like this or is this a bald patch setting in?
I am nearly 40 and I noticed my hair is thinning. I did a search on thinning hair and I read it can be caused by low iron. I do have low iron so I will take iron supplements religiously from now on.
