Our expert says:
The correct way of diagnostically confirming a fungal infection is to do a) Wood's Lamp(not very effective) b)Microscopic examination of the hair and c) Cultural test(takes 3 weeks for result - most effective test).
If the tests are positive then I would treat systemically with Itraconizole, Terbinafine, Fluconazole or Grisofulvin. Topical treatment with lime sulphur dips has been reported in the literature although I have never used this technique.
I hope this info can assist you with your decision.
