I purchased 240 hair strands and the glue gun to apply them but I am kind of hesitant to begin, I wondered if anyone had used a glue gun before? Or if you know how exactly its suppose to be done and if the hair is suppose to go directly on the hair or on the hairline?
Thank all for your help

If you are referring about the fusion method. Hair extension hair is added directly to your own hair using sticks made for extensions placed in a glue gun.

Applying hair extensions is not something you should attempt to do by yourself. It's best to have a licensed cosmetologist or someone who has experience with hair extensions apply it. I recommend going to a salon near you or a beauty school to have the process done.
