kind of OT - surgery and hair

I'm contemplating a few cosmetic procedures and I'll be under general anesthesia for 4 hours.  I've heard that the trauma of surgery can cause hair loss, and I've had a history of hair loss over the years from unknown causes which is why I wear extensions!  I'm terrified I will lose more hair and it's causing me to reconsider the surgery.  Anyone who has been under general - did you experience hair loss?

the anesthesia is what does a number on your hair, i have gone under a few times and the main thing i experienced is my hair felt dry then sorta fly away for a couple weeks, just condition and take lots of vitamins, you should be fine

I've had a few surgeries in the past couple years that required me to be under for lengthy periods of time and I was okay with hair loss.  I was under significant stress at the time due to concern regarding the health issues (all is well now) and it didn't seem to affect my hair in a noticable way.  Good Luck!

thanks sooo much guys!  I feel like I'm being so irrational about this but I can't get it out of the back of my head and I don't want to regret the surgery.  Btw, the procedures I am having done are rhinoplasty and surgery to correct a deformity of my ears.  It's very scary as I've never had surgery before!

I just had breast augmentation a few months ago (under for about 2.5hrs) and had my extensions in during the surgery. I noticed no changes at all. No hair loss, no extension issues or anything even related to that. Hopefully you'll be just fine!
