Ishaved my head the first week of december 2017, it’s been almost 2 years since i shaved my head and i haven’t cut it at all. i died it once with a ash blonde box dye which made it more ginger but other than that i don’t straighten or use any heat to my hair, i air dry it, and never wrap it in a towel when i get out of the shower. i wash it about twice a week. should i cut my hair? even though it looks pretty fine already, my sister tells me otherwise. saying i need about an inch cut off
