Getting your hair hopelessly tangled up in a brush, particularly a round brush, has probably happened to every woman with long hair at least once in her life. The key is to stay calm and stop brushing, as you could make the tangle worse rather easily. Take deep breaths, don't despair and certainly don't resort to scissors: while cutting the brush out of your hair is a quick fix, it's also a surefire recipe for an odd, lopsided hairdo.
Slide the knitting needle or smooth chopstick underneath the base of the tangle, so that the bottom end of the needle or chopstick is touching the base of the brush.
Wiggle the chopstick around trying to loosen pieces of hair from the grip of the brush. Start in sections: loosen hair from the right end of the brush, then work to the left end of the brush, and then relax the tangle in the middle of the brush.
Add a quarter sized amount of conditioner to the top, bottom, sides, and middle of the tangle. This will help for smoother de-tangling.
Unravel the brush from the base of hair. This will be difficult, so go gently and slowly, sliding out locks of hair that block your progress with your knitting needle or chopstick as you go.
Gently untangle the remaining strands with your fingers.
In Step 3, you can always wash the conditioner out of your hair when finished as it is a lot of conditioner in a concentrated area. It is better, however, to use more conditioner to lubricate the process than risk damaging the hair.
