Tell your parents that 你 think 你 have lice and ask them for help. There's special shampoo for getting rid of lice, so, if it turns out 你 DO have lice, try some of that. Also, don't share anything that has touched your head with anyone, just to be on the 安全 side.
go to the pharmacy and get lice shampoo. (and if 你 live with your parents tell them. partly so they can help and partly so they dont all end up catching it too). lice wont kill 你 but its a pain in the 屁股 in 你 dont get it treated, so do something as soon as possible.
你 do a lice treatment (this involves your parents). This includes using the lice shampoo and then using a lice comb comb them out and pull out the eggs. 你 may have to do this once 或者 twice before 你 get rid of them. If your case is really bad probally talk to someone professional that would know how to get rid of them.
