If I do exosomes again will it cause a massive shed to where the treatment isn't beneficial?

I had exosome injections and caused a massive shed losing half of what I had left. My Dr says some people experience that on the first treatment. Treatments are recommended once every 2 yrs. If i do exosomes again will it cause a massive shed to where the treatment isnt beneficial? I cant find one thing online saying any adverse effects of this treatment. Do exosomes cause more harm then good for some. I am on oral medication, vitamins and use lasercap. Shedding stopped once finasteride was used
