I'm not sticking up for her in any way here but looking at it from the other side, maybe companies work with her because they think she IS relatable.
Yes, I see that showing peeling feet & not showering/washing hair is disgusting to some people but in reality it IS real life. Whether it needs to be documented or not remains to be seen but it IS things that people do day in day out but I guess don't openly admit/talk about.
I follow a very well respected influencer and imo amazing lady who doesn't always shower instantly she leaves the gym ....
One of my girlfriends didn't wash up or shower for 2 days last week because she was exhausted, was on her own & not feeling great
I sandpaper my feet with a foot grater thing
I think we all do things that other people might think is disgusting .... I'm running on here but I think my point is, Companies may well think, that BECAUSE she's far from a clean freak, can be quite open about a lot of things & appears to not care, that that is relatable & often real life to people
I hope I've got across what I'm trying to say here without sounding like I'm raving about her because that isn't my intention
