can you suggest me a hairstyle?

I have diffuse thinning and currently using minoxidil. My current hair is 1.2 to 1.5 inches long on top. Do you think I should get a buzz cut with faded sides or grow it out more to get a crew cut or regular tapered cut?

The hair would cover more area if it was longer.

I would grow it another inch.

If you want to try short hair, than by all means buzz it, but don't go lower
than an inch.

As a diffuse thinner myself, I can say that my hair always look better longer than it does short. I try to keep the hair on top of my head between 2-4 inches. I would love to rock a buzz cut, but if I go shorter than 1.5 inches my hair looks very thin on top.
