There really isnt any way to reduce the diameer of hair through any method.If you want to thin out the hair, as in reduce the number of hair growing on your face, then electrolysis is definitely the way to go here. I can tell you this having had 12 sessions of laser myself, which left a patchy result and most hair regrew over time.
Whether laser or electrolysis , hairs can reduce diameter temporarily if the energy thaat reached the dermal papillae is insufficient, but sufficient to cause some damage. Over time however that damage is repaired by the body , and often the dermal papillae ir repaired with more blood supplying capillaries.
TL:DR : Thin ( as in quantity/hair density) , and the nbest tool, is yes electrolysis ( just like I said the first time !) . The electrologist can pick and choose the individual hairs to destroy, versus a laser which works over a 1 inch by one inch area on you face.
