Rhinoplasty + Dye Q&A

I'm 5 weeks post op and I dyed my hair but while it was being dyed I found that the chemical smell from the hair dye was very strong. Has this caused any damage or irritation to my nose? Thanks

My surgeon done a facial graft on me during my rhino/septo, and i am planning to dye and blench my hair. My cast is removed and now im taping only for 5 days. Can i still dye my hair even though i had facial graft. It wont affect it? Thank you

Is there any way a day before my surgery, dying my hair that the anaesthesia could do any permanent damage to my hair. Being a male, I do worry about losing my hair but hope that won't be until my 40's and I'm just worried if the anaesthesia could have had any adverse effects on my hair a day after dying it. Should I mention this to my surgeon?

I had a septo rhinoplasty 2 weeks ago, and I wanted to know how long should I wait until I can start laser hair removal sessions, ( Upper lip and chin ) ? And is it ok to dye hair after the surgery ? Thank you
