Two years ago I donated 15" of beautiful naturally red, curley hair to Lockstolove. They sent such a beautiful card in return. My son started to grow his hair just for a kick. He just had it cut and donated 12" to lockstolove. His is curly too, dark brown. What a great thing for a college kid to do (Univ of Delaware, Masters in Technical Theatre) I don't think that I'll cut off that much again, but it was sure a good feeling once. They need atleast 10" to use.
