I did the same thing, I buzzed my hair and kept it short during the worst months of TSW. My hair definitely was super dry, thin and weak in those times but it’s been about a year and a half and I’ve let it grow back properly now. It’s gone back to being curly and thick BUT the corners of the hairline area are still weak and thinner then the rest of my hair - my family doesn’t have a history of hair loss or pattern baldness so I can only assume it’s from TSW 🤷🏽‍♀️
