### input:
Hi, I have bumps on my scalp that itch a lot. These bumps come and go. Sometimes they are there for 2-3 days and sometimes they diasppear in few hours. But they cause discomfirt and severe hair loss.  Initially they started as harmless small bumps and over few years they have taken this form. Doctors gave me shampoos and local applications - which did not help even a little. I have used oils like ashtabringhandri tailam etc. The itching reduces when my hair is wet or oiled for sometime, but comes back again within few hours. I have stopped using shampoos with chemicals and hair colour sometimes for a month or so, but still the bumps keep coming. Some shampoos have an aggavating effect, (Shampoos like Johnson Babies, Head and Shoulder etc produce more bumps and itching) some have no effect (shampoos like dove - results in neither increase nor decrease of bumps). I am 47 year old, female, not diabetic, over weight, on a break from work and hence not stressed (Currently). I have no other problem except severe itching, bumps and accompanying hair loss. the bumps are mostly on the back of my head and sometimes on the crown. My hair falls off like as it it is too weak to stick on to my scalp. It falls in long strands, many many at a time thruout the day but my pillow does not have any hair fall sign when I get up... I feel I need to take some medicines internallysince this is an infection....

Hello. Thank you for writing to USI have gone through your query and I have noted your concern. Perhaps you have an oily scalp and the bumps are nothing but Scalp acne. I suggest you to take an oral tetracycline e.g. either Doxycycline or Lymecycline for a few weeks (4-6 weeks). It is a prescription medication. In addition, you may use either a ketoconazole based shampoo or a Coal tar with salicylic acid based shampoo, every alternate days. Lather it well on to your wet scalp and allow it to act for 7-10 minutes before rinsing it off. Regards
