How to regrow hair on GSP

[Labradinger]

My gsp had a bunch of bumps growing down both ribs. Happened right after a food switch so vet said switch back and wait. Weeks later, no change. Tried a special shampoo-nothing. Blood tests finally showed hypothyroidism. Between those meds and some prednisone, bumps are down, but all her fur fell out on the bumps. Looks terrible. Any product known to regrow hair?

Not a vet
My Doberman was stung by something likely a bee or wasp couple years ago he broke out in hives on his one cheek and neck vet put him on 14 days steroids can’t remember name now bumps went away but hair was gone on the scaly looking spots I just dabbed castor oil on them not heavy just little goes long ways it soaks In Deep softens the skin so long as it’s in area they can’t lick now wouldn’t know he had a problem But we know he’s allergic to insect bites
Water down vinegar rinse helps with PH

Vaseline will also soften the skin up. It does miracles on those big calluses they get on the elbows. I had a hypothyroid one that did the same thing. The hair came back some but was still thin. The CRP. fields would rub it out pretty quick. She looked like hell from mid-season until a few weeks after.
