Is 4-5 weeks too often for brow lamination?

I’m super tempted to book another brow lamination appointment because my brows are losing its shape and direction, and it’s only been 4 weeks. They naturally grow downwards and are super thick and coarse (cons of having Asian hair). My tech told me my hair is really stubborn too and left the solution on a tiny bit longer so it could relax. I also oil my brows every single night and do occasional masks/conditioner to keep them hydrated.

I’ve read everywhere that 6-8 weeks even 10 weeks is optimal for a brow lamination but my hair is sooo stubborn I feel like that is too long to go in between. Is going monthly excessive? I just really hate my brows when it’s not laminated.
