Sorry don't know what you mean by Lodi?
I haven't had hair loss losing weight this time around, but once went travelling to a country where I had food poisoning on and off for 3 months and lost LOADS of hair, so I do feel your pain. The only plus (though not sure whether it'll make you feel any better short term), is that it did grow back thick again, once I could keep my food inside me.
I think hair loss can be caused by a lack of calories, or other factors such as a nutrient deficiency. I'd take a multivitamin (every other day, to improve absorption), if you're not already, in case it's the latter, and manage any stress etc. But if it's the lack of calories itself, there's not much you can do ime, and the damage might already be done short-term, because the hair loss usually happens during the next cycle of that follicle iirc. That is, the calorie restriction last week, may already have "programmed" some of your hair follicles to lose / not regrow for the time being.
A side note, when my hair thinned, I was recommended an oily scalp massage to slow it, by lots of people trying to be helpful. I really, really wouldn't recommend!! It seemed to knock a load of my hairs loose when I tried it (might be useful under other circumstances idk) and the poor man doing it had to stop because his hands were covered in lots of greasy, dislodged hairs 😬
