An iontophoretic device for stimulating growth and regeneration of hair, comprising means 5 for applying to the scalp a unipolar, low-frequency (0.5- 2Hz) square wave pulse superposed with a diphasic action potential wave (pulse width 1.6-5m.sec.; pulse period 33-50 m.sec.) to introduce medicament into the scalp. The medicaments preferred to the invention are certain photosensitizing compounds having a common amino vinyl structure, such as 2,2'[3'-[2(3-heptyl-4-methyl-2-thiazolin- 2-ylidene)ethylidene]propenylene] bis[3-heptyl-4-methyl thiazolinium iodide], 2-[2-(3-heptyl-4-methyl-2- thiazolinium-2-ylidene)methine]1-3- heptyl-4-methyl thiazolinium iodide, 6- [2-[(5-bromo-2-pyridyl)amino]vinyl]-1- ethyl-2-picolinium iodide, and 2-(2- anilinovinyl)-3,4-dimethyloxazolinium iodide. <IMAGE>
