My hair wont grow 🤷🏽‍♀️

Im not sure what im doing wrong. I keep my ends trimmed, i keep my hair in protective styles (braids) and theyre never too tight because i have such a tender head. I dont even remember the last time I applied heat. My hair is stuck in this same length ever since my big chop two years ago and my big chop was amber rose short. Any tips on why its not growing? And I purposely dyed my front hair this color so that i can see the new growth when it starts to grow. Out and still nothing. Its been almost a year and my hair is still the same color no new growth. 😢😢😢
