I will always say it, eyelash extensions look beautiful on any type of woman, no matter who she is, and regarding the shampoo, the only advice I can give you is to make sure it is of high quality, because if it is a cheap, lousy shampoo quality can irritate the eyes of the girl who is going to clean the eyelash extensions, I don’t know about the store, but if I find one that sells only quality products I will gladly recommend it to you
