Does the crown grow slower than the front

I searched the sub but did not find an answer, sorry if it has already been asked. I’m on the big 4 since the end of November. I know it’s too early to draw any conclusions but I already had very good results on top and front, managing to fill an area on the right temple that has been bald for 15 years! However hair on the crown is still rather thin, as if it’s lagging behind.
