Welcome to HCM.
I am suspecting white piedra
infection of the hair. This is caused by a fungus called Trichosporon begeilii. It is common in hair of scalp
, armpits and pubic hair. The hair has small white nodules attached to them. It does not cause any itching as skin involvement is not there. I suggest you get a KOH (potassium hydroxide) examination of the hair to confirm diagnosis.
Shaving of the hair is treatment of choice.
Get in touch with a dermatologist
for prescription of antifungal cream.
