hi im dr satya and welcome to health care magic
is a recurring infection of the hair follicle super added with inflammation and reaction.
You said that the problem started after a visit to a barber with possible mix up of utensils, considering your theory then the folliculitis will be most often of tenia or fungal infection
and not that of lichen planus
. lichen planus also affects hair follicles and will present as loss of hair or fine black spots over the head. The possibility of your infection responding to oral medication is high and you will need a few applications of celestoderm.
Please do visit your nearest dermatologist
for a good examination and suitable prescription. Im hopefull for a remission and a good soulution for your problem.
feel free to contact.
