I would like to know if I may trim my hair during the omer , I am applying antibiotic to the scalp and it is difficult to apply with long hair. I’ve been trimming every week/two weeks.
It’s not to look better , is a really close buzz cut.
Thank you very much
Yes, haircutting is permitted when there is a medical need.
