Hey,
Don't worry i have the same problem and on top of that lots of hair!
I currently use something by Schwarzkoff it is called Herbal Konzil. I don't know if it is available where you live, but check out your salons or else online. It is my life saviour, it is a treatment conditioner that protects your hair and if you use it in the shower leave it in for 3-5 minutes and use a comb from the bottom up and start combing the tangles out. Also, you can flip your head over and gently glide your hands through your hair from bottom uo and eventually throughout the whoole thing.
Hope this info is useful, good luck
