Your hair is very beautiful! Reminds me of my own.
The very best advice that I can give you is to buy deep conditioners with behementrium sulfate. This ingredient provides soooooo much slip its ridiculous. The deep conditioner I currently use is Dominican. I believe its called baba de carcol (yellow and white with a picture of a snail). If you wet your hair and apply this on your hair with a plastic cap and sit under the dryer; by the time you detangle it should be very easy.
