How do I stop the itching on my head!??!?

ok, so last summer i got lice, and it was a nightmare. i’m already naturally anxious, but throw in lice and i’m crazy. i found out and my parents treated me with the shampoo . i also found my best friend got it from me, but we both ended up fixing the problem , and we thought we were both cured and all was well. but then i started getting these small itchy bumps on my head. i ignored it, but throughout the entire year i’ve been worrying and i’ve also gotten these little itchy scabs on my head that won’t go away. i’ve tried dandruff shampoos but they wont work. now its this summer, and i still have the problem. i don’t know what it is…lice, bad dandruff…but i’ve told my mom and she told my to ignore it. my head is so itchy and i don’t know what to do.
