Funny, this was a topic of conversation with my neighbor last night. She bought some from this website: https://www.hairclippy.com/ and they are really good! Her 6 month old has a lot of hair and they don't move. They are not cheap and she is on a budget but she says they are worth every penny! I tried it in my daughters hair which is thinner and it didn't move in her hair either...we are going to place an order any day.
