Should a man invest in pheromones?

I realized that looks maxing probably isn't enough for someone who is 5 out of 10 like me. At best I can push it to 6 out of 10, and this is even assuming a mathematically perfect haircut with AI doing all the statistical calculations regarding hair, such as what type of hair attracts women the most, what type of hair has highest success rate.

But then I decided to read some science, and apparently pheromones are a thing.

I think I already have enough pheromones given how rare i shower and how rare I change my underwear, so I am a bit unaware of how those pheromones help.
