@harleytiger,

My facial hair under my jaw never did go back but I also had Cisplatin chemo (which intensifies the effects of radiation) and Photon radiation back in 2008 for left tonsil cancer. Nice I don't have to shave there but looks weird as it grows on my right side if I grow it out which I don't anyways so no big deal as my beard is neatly trimmed up to my jawline.

Blessings,
Rob
