I turned 40 this year and my hair is getting thinner, and I think it happens when I brush it. It has never been thick, but it is getting worse. The individual hair strands are thin and my hair gets tangled very easily, I often wake up in the morning (I don't sleep with a pillows, don't like them) with matted hair that is hard to detangle. For some reason it's really bad in winter, it's like the matting is caused by coat necks and scarves. Tying it up or plaiting it doesn't seem to help.
I have should length hair and I get a cut every 3 months or so. I wash every 2 days and I always use conditioner. I never blow-dry. I use a tangle teaser hair brush. Most days I tie my hair up in a pony tail.
I eat a good diet (recently went paleo), I make sure I get good sleep and I exercise.
I have never been very good at hair! I can't make a French plait to save my life and I never know what to do for special occasions. I never use hair spray or similar. Just so you know my level of "education" ;)
What can I do to stop my hair from breaking and thinning?
