I have known several women going through chemotherapy, including some very close friends. None looked that good, nor did their baldness look that neat. She looks like a healthy and rather cute actress playing a cancer patient.
I too have known a few people with cancer who went through chemo. Most shave their heads to avoid it falling out in “clumps” as that is distressing. The part that gives her away is the close up picture. Chemo makes all your hair fall out and I mean ALL. One chick on chemo had no eye lashes and eye brows and did not pencil them in nor use false eye lashes, in my opinion she looked like an alien from the X-Files just creepy. The chick in this picture has her lashes and brows.
