What would be considered too high for a polycount

Hi everyone, 

I recently started using cc (hair and clutter only for  now) and as i understood the poly count is something about the numbers of squares used to make an item (please correct me if i'm wrong !). 

So i wondered what would be too high a polycount especially for hair cc. I won't lie i downloaded about 20 different hairstyles but haven't taken into account the polycount. 

I know that if the polycounts are high the game might lag, i haven't nooticed too much of a lag for now.

Maybe i should say that i prefer using maxis match cc, i have actually found a haircut i liked and the polycount was 22k, is it too much ? 

I can't seem to find a clear answer for this. Any tips or thoughts are welcome !
