71 Year Old Woman Experiencing Hair Breakage

I am female, age 71 and have a question. My hair has been breaking off quite badly for over a month. My Physician says I am not taking medication that would cause it. I have never dyed, bleached, or stripped my hair but I do wash it daily. I have been treating it with the Nioxin treatment kit for about 3 weeks but see no improvement. I do not brush it, use wide comb and have it man cut short. Have any suggestions for stopping the breakage?

Try a good conditioner made for dry hair and see if it helps. Check with a good stylist for suggestions.
