KNOT today!

One thing newbies to the natural hair world complain about is being able to detangle their hair without pulling their brains out. It's not the traumatic experience people make it out to be.
Remember that you are not relaxed anymore, so the ability to comb your hair from root to ends is now null and void. You can forget about using a fine tooth comb of any kind, you'll be asking for trouble.
With the hair being in a natural state, knots will become apart of the equation of curly hair growth. With that being said, you may need to change your daily regimen.
Shampoos can sometimes do more harm than good when shampooing the hair. It's capable of creating more knots when you emulsify it through your hair. So try just shampooing the scalp and then pulling the shampoo through your hair.
When detangling natural hair, gently start at the ends using a wide tooth comb and your fingers. Make sure the hair is wet and with conditioner. It makes it easier for the comb to glide through the hair and use your fingers to gently pull the hair apart.
When pulling the hair into a style, it prevents friction and knot creation. Wearing the hair up means the hair is in a fixed state and not forming knots with all the other spiral strands. If you like to wear your hair out, be sure to keep the hair properly moisturized. It will make it easier to finger comb out loose  knots before they form into tight ones.  
Lastly, remember to wrap up your hair at night. Hair that's free during the night is going to be knotted and tangled by morning.
