This is right up my alley, for me.

I have been suffering from a staph infection on the scalp for the last decade. I am colonized, and every time I do a cycle on Doxycycline I am clean for 4-5 days and it's back... The symptoms are puss filled boils on the head, sometimes bloody. Sometimes known as folliculitis.

I believe I am colonized, but I also believe my cat is also infected and we mutually retransmit it to each other as we share pillows.

It all started in the nose 10 years ago, unlocked all sorts of issues and permanently damaged it. Then it spread to the scalp. It seriously reduced my QoL and made visits to a barber a challenge. It increased my hair shedding aka more prone to balding.
