How Can Hair Loss With Dryness Be Treated?

Hello, I desperately need some halp with my hair. I am presently going through a messy divorce but do not feel too stressed about it and am coping well, however all of a sudden this last fortnight, the hair accross my fringe and at the side of my face seems to be dying off. I have had it trimmed to see if that would help but no sooner was it cut, as soon as it began to dry, the frizz returned with avengance and has progressively got worse over the last week. I am treating it every night with conditioner left in, olive oil amongst other things and every time I wash it, I use a treatment conditioner too but nothing is working. My hair is my crown and glory and this is really starting to get me down. Please help..Cathy
