Review (4/5): Easy to use  but gets itchy
Easy and reasonable cost, but it does get the scalp itchy, wouldn't recommend leaving in for more than a day. Good coverage in a pinch. It does seem to splatter sometimes, possibly need to clean nozzle after spraying? Best to apply before makeup or you'll need to touch up your face due to splatter.
Good for larger areas and not on small hairs near face.
