Eyebrows regrow after yag laser?

The laser tech chipped away tops of my brows with the yag laser during full face laser sessions (she did this for two sessions). what are the chances they will grow back, it has been 5-6 months and I've only seen small hair growth? I am hoping they are only in prolonged dormancy stage, and the longest they will last is a year!! the setting was pretty high in fluency 40-45 joules, but pulse width was only 15-10 m/s respectively. please i hope this is encouraging for regrowth...only two sessions. what can I expect? my hair very dark but I understand yag is not attracted to melanin?
