I think Lamisil
is a poor choice in todays medicine for your problem, and the problem till now is not cured.
I would like to see a close photograph of the skin in taken about 8AM in morning and on outdoors.
I would advise applying Selsun
shampoo and keep it for 4 hr on skin then wash, apply in the evening., Expose the skin for tanning
in the morning sunlight for 10 minute daily. It will take about a month before cure
