Hi, I have extremely itchy scalp in the top middle of my hair and there is nothing visible, like a fungus, rashes or dandruff, only that my hair is extremely short where it itches, it even itches after washing my hair. I ve tried tea tree oil and selsun blue and natural no-sulfate products and still it itches and my hair has not grown in the place where it itches. Also, I do not have insurance so i cant visit a dermatologist. But i strongly believe there s something else happening in my scalp.
