My biceps is having a plateau right now, will one week of rest break through the plateau?

all of my other muscles group is increasing weight like nothing but my biceps seem to be at a standstill and i just can't add more weights to my biceps because it can't do it but the rest of my muscle group is growing strong fast but not my biceps. will one week of not working out the biceps help it gain more strength? my brother said so since i've been working out my biceps a lot lately
