Q: If there is no or very little hair on pubic areas is shaving still compulsory?
A: If there is no hair, there will be no need to shave. If there is little hair and it has lengthened, it will be necessary to shave it. It is necessary to shave at least once every 40 days. So if the hair was left for 40 days, then regardless of how short it is, one must shave. Not to do so is sinful.
