Luckily my husband did not lose the strip across the back where the radiaton exited. It would of looked awefully strange since he already lost the hair on top. He did lose the hair on the back of his neck but I just noticed he has some fine hair coming in on one side. As far as his beard he had lost everything below his lips but it has returned on his chin in the last month or so. He needs to keep freshly shaved or his sideburns look like porkchop sideburns which I do not like at all because of the missing beard. He sure saves time on shaving these days!!
