Update (2018-12-05): Since Danny of Mentality Nail Polish has generously sent me a cease and desist for defamation as seen in the comments section, I’d like to interrupt your regularly scheduled programming to clarify (even though I think it’s pretty damn clear already) that the causes of the issues are science-based opinion and speculation. 

Welcome to every nail polish lover’s nightmare – nail disease. Wearers of Mentality Nail Polish have been waking up to this horror:

Thanks to @dmm_nails for letting me use images of her poor nails!

The technical term for this is onycholysis – when your nail detaches from the underlying nail bed. It’s painful, it’s inconvenient, it’s ugly, and you have to wait til it grows out to recover (if it ever does). There are lots of write-ups on the multitude of legal and ethical fuck-ups that Mentality Nail Polish have made in handling this issue, so I’m not going to rehash that in this post (you can read all about it at The Mercurial Magpie and Ashley Is Polish Addicted, amongst others). Like many others, I’ve been racking my brains wondering what exactly went wrong.

Of course, we won’t know for sure until someone gets analysis results back from a lab. Mentality “almost have enough funds” for an analysis now (although they’ve reportedly known about this problem since September last year, and a GCMS can ordered for under $100 and they haven’t even done that, so I’m guessing we’ll hear the results in 2020 or after an injunction?). But since they’re going full Laganja on this one, I’m not holding my breath.

In the meantime, here’s my analysis of all the speculations that have been flying around. Keep in mind that these are just speculative hypotheses and my opinions on them only – they’ll change as we get more complete information (which is pretty tricky, as Mentality have been deleting their posts, and I’m having trouble finding some of their past statements… I’m sure a lot of links I currently have here will die!). As I’ve read more, I’ve changed my mind about 7 times about what I think the most likely cause is. I’ll be updating the possible explanations as they develop.

What we know

• Indie makers typically buy a pre-made base from a larger manufacturer, then add tints and glitters. This is what Mentality have supposedly been doing.

• From Mentality’s Facebook page:
  • Mentality were using Tevco and Fiabila base (3/4 free), but sometime late last year/early this year they switched to a base from Arminex (5 free – parent company of Nubar). They’ve since switched back. They do not make nail polish base themselves… “yet”.
  • The problematic polishes aren’t isolated to the neons, although the neons were very popular and consumed whole barrels of the base, so they’re the most commonly reported.
  • Mentality degassed all the bases to “remove air bubbles and found that Arminex base is very foamy, compared to the other manufacturers whose polish base does not foam upon degassing.”
  • Not everyone who wore them were affected (around 40 people have reported reactions to Mentality so far). The earliest case was @spilledmilknails, a Mentality swatcher, in September 2014.

• From people who own the affected polishes:
  • The polishes with the different base smell very “chemical” “like melted plastic”, and the smell seems to have gotten worse over time.
  • Some people were reporting stinging, itching and redness upon application.
  • People who experienced nail detachment generally wore them for longer periods, while swatchers who removed them immediately were generally affected less. There are exceptions though – apparently someone swatched them for 4 hours and ended up with nail damage a few days later.

Faulty Arminex Base Theories

This is the angle that Mentality have been pushing, which makes sense because it means less liability for them and hence their best chance of getting out of this without being buried in a steaming turdpile of legal troubles.
