My reason is a bit depressing but I'll share it anyway.
Now I don't about this in depth but it made sense to me so I stopped.
15 years ago I wore nail varnish all the time. I loved the stuff. I still do... Which is why I need to get my hands in this washable nail varnish so damn bad.
Anyway... You know how your wudu is incomplete when nail varnish is worn... Well, 15 years ago I was in a car accident. Which left me unconscious for a while. (I wasn't hurt - physically) When I woke, my first thought was, if wudu is incomplete then what would happen at the time if ghusal. (When they wash you at your time of death). That was the last time I wore nail varnish, cause the only guarantee in life is that we will die. If can happen at any point. And I heard that removing of nail varnish from a dead person is not allowed.
That was enough to scare me away from the stuff.
So, I saw on Dina Tokia's Vlog that Nails inc had sent her wash off nail varnish. I googled this and found a company called "s n b" alway do it for mums to be. (safe and beautiful).
I needs this stuff in my life... I love dark reds... I found this in boots... Only applied it for the photos.
(Normal nail varnish- part of a clearance in boots)
After three coats I got the colour I wanted, but it's became to soft and not very neat.
