Is the sign for the noun 'a comb' the same as the verb 'to comb'?
Yes, they use the same handshape and location. However, in ASL, nouns often have a smaller, repeated double movement, while verbs have a larger, continuous motion. For the noun 'comb,' you might do two quick, short motions.
Can I use this sign for brushing hair?
While similar, the sign for 'brush' typically uses a different handshape. For 'brush,' you usually use an 'A' handshape or a modified fist (like holding the handle of a hairbrush) and make the brushing motion, rather than the clawed handshape used for 'comb.'
Does it matter which side of my head I sign this on?
You should generally use your dominant hand and sign on the corresponding side of your head. If you are right-handed, use your right hand and make the combing motion on the right side of your hair.
