Shaving and Body Hair

I have aging off in my newest game save. I have to say the eldest child in this family is a YA. I gave him a limited beard and then noticed some time later, it had grown quite full! I had the option to shave or to shave to the limited option. I chose the latter. He looks good with some facial hair, but a full blown beard, not so much. LOL His father has a fuller beard, but so far I haven't see any changes in that.
