That happens to me with Got2b too. When I used regular hairspray i only got white stuff when it dried and got hit or something. So, I guess it's pretty normal, but then again I put on LOTS of hairspray.
ROFL...My girl said the exact same thing to me bout it looking like someone had jizzed on my head. from what i can work out if u spray to close and dont rub the spray into your hair when u dry it, it seems to dry as a foam on the surface of the hair. either spray from further away and just add more layers. or spray close and before drying work the spray through your hair.
