Permanence?

I’m between a Type III and IV,very coarse, black hair, and have had two sessions on my chest. The first was on GentleMax (Alex) at 18mm/10j. The clinic then switched to a GentleYag and I did my second treatment at 18mm/24j.

I’ve read on here that the minimum with Alex to be effective is 14j. I’ve also read on here mixed views on Yag being effective under 30j.

With both sessions, I had very good shedding starting around day 7, and both times the regrowth has been much thinner hair.

My question is, of those hairs that came back, if I were to stop all LHR removal (which I’m not), would the hair continue to grow back with the same thickness, or could those follicles later revert to their original thickness. In other words, could those supposedly “low” settings cause a temporary difference in the coarseness of hair, or what I’ve achieved is with my to stay (of course not counting new hair growth that is due to age and would come anyway even with the strongest settings possible)?

Thanks
