Scalp Follicuilitis

I am a university student of age about 21 years. I am very much puzzled with my Scalp FolliculitisFor a long time, I am suffering from Scalp Folliculitis and losing hair, a brief history is given below.

In November 2015, it was found that a number of warts on the scalp like coli-flower. Some of them were very big in size. I got homeopathic treatment at that time. By taking Homeo medicine all warts gone but a number of sore (folliculitis) found on the scalp and losing hair. My hair was very much thick but after taking Homeo medicine warts disappeared but losing hair of about 60%. Homeo Doctor change medicine several times but found no improvement in more than 2 years. The Doctor did not tell the name of medicine.

Then, I left the Homeo Doctors and went for allopathic treatment for 3 years but no improvement.

Now again I have changed the allopathic doctor and gone to Home Doctor (Not the old one). I am taking homeo medicine again for about two years but the folliculitis not disappearing. It is white color, no pain if not touched, having sticky pus, no bad smell, increase in hot weather or if I sweat. I am losing hair, very few numbers of hair getting gray. Here in Bangladesh, Home Doctors Do not tell the name of medicine.

Some picture of Folliculitis is attached.

Which medicine can I take?
