<s>[INST] Hi, my daughter is 4 years of age and has been treated for scalp ringworm5-6 times.  No one else in the family has gotten a ringworm and I dont think she has gotten it from anyone at school because she has since changed schools and yet they persist.  I am a nurse, so I make sure she takes her full regimen of griseofulvin as prescribed, but yet the ringworm returns.  This last time she went approximately 1.5 years without the ringworm because the doctor suggested taking the med twice a day to keep the levels in her system steady and give with whole milk, since we drink soy in the family. And this worked, and i thought it was gone forever, until this week when I noticed a new lesion in her scalp.  Can she possibly have a genetic predisposition.  Why does she keep getting this scalp ringworm?  Im starting to wonder if she has a problem with her immune system. [/INST] Hi repeated scalp ringworm infection could be due to any of the underlying disease mentioned here.a. Type 1 diabetes decreased immunity doe to continuous intake of steroids/ any other immunocompromised state-HIV, cancers etc or it could be due to some pet animal in the house which is infecting her repeatedly. Try keeping her scalp Chat Doctor.  Try leaving her hair and not tying a pony/ plat, to avoid any sweat accumulation in scalp. Use anti Dan </s>
