Who’s likely to experience initial shedding side effect with the Capillus cap?

My dermapathologist suggested LLLT for my AA. I’ve seen some hair growth from my treatment of 3 years of Rogaine, finasteride and Spirolactone. But my temporal follicles are not responding well. I read that some experience shedding when first using the lasers. why do some patients experience this, and some don’t? My new Capillus arrived and I’m terrified that I’ll shed - yes, I know that it’ll be temporary. Each time my doc increases my finasteride dose, I shed. I have v sensitive follicles!!
