Hello headline help,
To ind out exactly what is going on with your scalp you need to see a dermatologist and get cultures taken of your scalp.
You might even need a hair analysis.
It sounds like you could have an infection and once that is treated you scalp should start to look a lot better.
Also ask if it is ok for you to take a multivitiamin and extra B-complex to help your hair regrowth.
Best Wishes to you,
