it's due to sun bleaching. Some peoples hair is capable of photobleaching. For some people the lightening can be extreme, as is in my caseuhh ,she has bleached highlights, so no, her hair isnt totally natural. plus, she's still having periods, as soon as she goes in menopause, she will match her husband. stress free no way. no such thing. and hey, he's an old guy, I dont think he looks bad, nice head of hair for an older man. I wonder why she's not darker skinned though. that seems weird to me for someone who is living the bush life...
