Myrrh

I feel you.
My surgery was in march and I started to shed hair in may. It's quite heartbreaking, especially while washing hair, it just comes off all the time and the amount is... really something. My only hope is that it will stop falling off, cause it's been two months already and at this pace I will be bold by the end of the year.
Do you know if it's better to keep your hair shorter during this time? Like visually.

you're fine. And you're right - you're starting out at a lower BMI than a lot of us, so you're likely to lose more slowly. There are so many things that affect your rate of weight loss - age, gender, starting BMI, genetics, metabolic rate, your activity level, how closely you stick to your program, whether or not you lost a lot of weight prior to surgery, etc. The only two of those that you have much control over are your activity level and how closely you follow your program. If you're doing well with those two, then that's all you can do. I was a slow loser as well, and I ended up losing over 200 lbs. So don't worry about it. You're doing fine.
