Shaved head after 3 years post hair transplant. Will it grow back to the way it was?

Hi there, I’m wanting understand whether my hair will grow back thick as it did 1.5 years post surgery. I recently shaved my head so it’s been 3 years since my hair Transplant. My hair is growing, it’s been a month and a half since i shaved it and it’s grown like half an inch. Will it grow back to the way it was? Will it thicken up as it did post surgery?
