My worst products are by far
TARIA CURLZ. The who line is pointless and did nothing for my hair. thank goodness I only purchased samples.
MIXED CHICKS STYLING CREAM. This product left my hair dry, frizzy, sticky, and with build up.
ETA: I also think KICK FOR CURLS is a waste of space, why bother when I can get the same affects using water in a bottle.
