If you go to Fortress you can buy a special electric shaver/razor used to give short "buzz" haircuts in salons--not too expensive--less than $200 HKD, I think. They have one type that is especially meant to use on children and isn't as loud as the other one. My husband and I bought the adult version in May or June this year and it works well. Just go to the counter that sells electric razors. In that way--you can cut your baby's hair and any male (or female?) hair in your family. I now do all of my husbands "haircuts" at home--especially in the summer when it is really hot. They have adjustable length attachments for the razor so you can choose your length. Otherwise, I think if you go into any local "barber shop" and tell them to buzz off all of your baby's hair they will do it for probably less than 20 HKD.
