You do need to ditch the polish as fungus loves damp and low light, exactly what layers of polish provide.
I put Vicks on but I also put:
- pure tea tree oil
- pure lavender oil
- vinegar.
Sometimes whilst I'm in bed and with my mini spray bottle I just keep dousing my toenails with vinegar or I soak some cotton wool pad in vinegar then use a plaster to hold it onto the two big toe nails and leave it on overnight.
Get as much fresh air to your feet as you can.
You have to file down the nails (never sharing it with other toes, keep your hands covered and don't re-use the file) and I don't just mean the length, you need to file down the surface of the nail or anything that you put on won't soak down into the nail sufficiently to do any good.
By late 2016 having battled the fungus for a year I thought oh fab, you've sorted it. But just a couple of months ago I could see it had come back - just in time for the summer! I've not been able to wear any shoe or sandal where my toes are on display as whilst they no longer look gnarly and yellow, the lengths of the nails are all over the place as I have to constantly file them down to keep removing the fungally bits.
It's fully managed though and I'd say I'm 80% there - I'm not sure if I'll ever get rid of it tbh! I tried Curanail and so on - didn't work and in fact tea tree oil / vinegar have worked very well. Remember to protect new shoes by putting a plaster over infected nails so the spores don't get into the interior of the shoe, and consider throwing out any slippers for eg that you've worn without socks so as to not reinfect yourself. I change tights socks every single day also to make sure I'm not reinfecting. Tumble drying items that might have come up against the spores is also an important step as it dries the item out such that the fungal spores can't survive.
Good luck with the fungal battle!
