So she had them done then agreed that they needed to be thicker and now doesn't like them? Did she not look in the mirror while they were been done?
Sorry, but they really aren't that bad, if she was twenty years younger they'd be bang on trend, they look like her daughters in that article 
My mate gets hers tatooed because she's so fair her eyebrows are none existent, they do look darker for a few weeks but it fades pretty quickly tbh, and it's all mentioned in the consultation. The lady who commented in the article sounds like she informed her about it all before hand.
My mate shaves off her natural eyebrows because that does look odd growing over the tatooed bit.
If she's really unhappy she can get some decent coverage concealer and shape them that way, it's semi-permenant so it can only fade and improve. She'd be daft to get any laser treatment on such a delicate area when it's likely to look nothing like that in a year or so.
