Because this is what drugs can do, kids.
This puffy face situation? I don't know if we're dealing with a straight-up side effect of booze and drugs, or if said substances actually caused a gaunt look that required copious amounts of injectable fillers to compensate. But either way, it's not good at all.
The hair, too, is obviously thinning, and while blonde is the best colour to camouflage that sort of thing (there's less contrast against your scalp), not THIS blonde. It's so brassy, it looks like a DIY Sun-In job.
Wouldn't you love to see LiLo with bangs and a shoulder-length bob (a lob), in a strawberry blonde colour? We also need to stage an intervention about the bronzer, heavy eyeliner and pastel lipstick. Poor LiLo.
