Dear Rabbi Simon,
Can you recommend how to get a kosher haircut for a man who is going bald in front of his head and wants to hide it? It seems to me that the type of haircut which is recommended in such cases is associated with the risk of violating the halachot about peyot.
Simplistically, I would have thought that a man who would like to obscure baldness would not benefit from aggressive hair trimming. But in any case, the “peyot” which must not be trimmed close to the skin are located in the area of the sideburns and in front of the ears. Every man who visits a (new) barber needs to be alert to this!
Rabbi Rashi Simon
