Experiencing hair miniaturisation, my question is: A shedding may occur during the first month of Laser LLLT treatment? (Photos)

I am 38 years old and have a miniaturization of the hair with a retreat of frontal line. I lost only 35% of my initial hair density and therefore hair transplant is not required. I followed two PRP sequences (2.5 mL each) in octobre 2016 but I experienced some hair shedding, then i decided to stop PRP injection. I am now interested by LLLT treatment. My question: a shedding can occur during the firstS monthS of Laser LLLT treatment ? Thank you
