So in August 2022 I had bleached blonde hair. I quit my job so I couldn't afford the maintenance anymore. So the cheap route ( worst mistake ever) was to buy brown box dye it was permanent. After that my hair just got thinner and thinner, It's stressing me out. My hair was so thick and full and wavy before. I cut my hair to my shoulders. Will my new hair that grows, grow back to its original thickness?
