This is correct. This is a reflexive verb that you are doing to yourself. This translates to, "Normally I brush the hair". If it was something like "Normalmente me cepillo el pelo de Anna" it would be incorrect because you are doing it to Anna, not yourself.

The answer is NO
the regulars verbs in present tense always end with an "o"
But some irregular verbs don't always end with an "o" =
SER ► soy
ESTAR ► estoy
SABER ► sé
