"Limited" is a weasel word, as it can mean anything. e.g. a "limited time offer" can mean it lasts for 2 days or 2 years, because it is not unlimited.

Likewise, sharing a limited amount of information with Facebook simply means they don't hoover up every single bit. Perhaps Facebook is not interested in those automated texts you get confirming haircut appointments...

On the other hand, if you just got a haircut, then they know that you’ll be looking for another one in a set amount of time (based on your hairstyle, which they also know from photos), and they could advertise hairsalons to you then.

I’m not sure their algorithm is this refined, but it’s not impossible.
