Hello everyone!(^_^)
I hope you are all fine
I just want to ask something.
I have taken an oath not to cut my hair ever again but I wonder if that will harm my hair or lead to hair loss or other unwanted conditions...
As long as you take good care of your hair (keep in clean, conditioned, and untangled), I don't think you'll have any significant problems other than the ends possibly becoming damaged over time due to exposure, wear and tear, etc. This damage is the reason many people with long hair get occassional trims (to remove split-ends).
Good luck, and keep us posted.

No!! growing your hair will not harm it in any way shape or form. Not taking proper care of it will though. Regardless of length.
