Black Human Hair

My wife and I found a lock of black hair, the man in the chamber of our children. The lock of hair was about six inches long and contains hundreds of hairs. He was placed in a blanket that was folded in a drawer under bunk beds for children. There is no way it got there by mistake.
The only people who have access to our house and have black hair team Southeast Asian maids who come each week for the other?
Is there a kind of curse they put on us?

What I know about magic involving the hair that you take the person you want lots to say. So if that is the hair of the maids' you might ask your kids. I do not think it is cursed, but you should definitely ask them what they are leaving tufts of hair around your home.
