Plucking immediately after laser treatment?

I have very course, dense, black chin hair which grows very quickly (everyday) and my technician has advised me that I will need 8 treatments every 3 weeks. After my first session yesterday, she told me I should pluck out all black facial hair that was treated in the next 2-3 days when it's above the surface, but will this affect my results? Also, does plucking facial hair promote the growth of even more hair and dormant hair? Thank you in advance.
