4 months post op

Okay so I have a couple questions. I'm 4 months post op from gastric bypass and I have hit a stall. Like for 3 weeks haven't lost anything. Is this normal? Also my hair is thinning at the top like where my part is. Please tell me that it will grow back ASAP!???

It's pretty normal for both-

i've not lost for 2 weeks and I'm 5 months out. As long as you are staying on plan and drinking your fluids it will come off. If you are not counting your stats in an app like my fitness pal and just winging it, i would be worried.

And I started losing hair about 3.5 months out- I have a ton though so not worried.
