How long does it take to regrow hair if protein deficiency was the cause?

Hi, AMOS family. I am about 8.5 months post-op and just went through a devastating hair loss. At least 40% of my hair fell out in months 4-8. It has stopped falling out now but is still very thin. I didn't think I had a protein deficiency, because my blood tests came back normal ... but I was reading on this site the other day that you need at bare minimum 60 g. of protein per day, because our post-RNY bodies don't absorb all 60 grams. I have only been getting in about 30-40 grams, which may explain my hair loss problems. I immediately bumped my protein intake up starting a few days ago. I try to get 70-100 g. of protein in everyday. How long until my new diet will cause my hair to recover? Anyone have experience with that?
