Imagine a helmet with hundreds of little spikes inside that sit on the scalp and secrete a tiny drop of topical formula. A person could dry and style hair first, then place the spiky helmet onto the head and press a button to secrete one dose. Does anything like that exist? I've heard of dropper based applicators, but what I'm talking about are hundreds of spikes that secrete such tiny drops of liquid that it doesn't run too much and so doesn't get into the actual hair as much.
