Will weight loss impact my new hair?

I would really appreciate your professional opinion on this matter: I have 10-12 kilograms of weight to lose. It’s been a long time since I did sports or any restriction on my diet. The reason of avoiding such dietary and physical stress is to avoid losing hair. Currently I am following a hair loss regime (since December 2019) that is giving me drastic regrowth of my MPB and is reversing it.
