grow light alternative

Are there any less painful alternatives to waxing or tweezing your eyebrows?
My mom doesn't want me to wax or tweeze my eyebrows. Are there any other less painful alternatives? Also is there any alternatives that have the hair grow back not so dark, because my eyebrow hair is light blonde.
Threading... You can barely feel it at all, and it is SO COOL!
It is by far my favorite way to have my eyebrows shaped.
