I use Gold Listerine morning and night in a dropper to apply under my nail beds and on top.You can also put it in a spray bottle.Just make sure it gets under the nail bed.It also heals my scalp. I pour it on my clean towel dried hair/scalp. It doesn’t effect my hair or hair color. Just leave it on and towel it dry . Do it until it’s completely gone from your scalp. I do my nails always morning and night and even after they have heal .

Yes , I still use it today everyday, under and on my toenails(especially after a bath or getting your feet wet). It seems to keep the nail Psoriasis under control.If I get lazy about it then I start to see a lot of nail bed separation.As for my scalp it completely healed it up . If I think I’m getting a flair I treat my scalp everyday until its gone.I’m 57 and I started using Gold Listerine when I was 13 years old..It also clears up pimples .I use it on my dogs too if they get a hot spots ..It’s been a horse remedy for years. people use it to clear up a type of fungus that gets on the horses skin and leaves bald spots .I think it’s the same thing dogs get too...What ever it is I know for a fact it works ..

Have read that soaking nails in the old fashioned good Listerine might help per People's Pharmacy siree. No idea if it does help, tho

I also had psoriasis under the nail and in many other places. I changed my diet majorly. No wheat flour or gluten, no refined sugars, got allergy tested but that also affect psoriasis flare ups, stop eating all I was allergic to. It helped the only psoriasis I have left is on my scalp and face under my chin. Everywhere flares up only when I eat something I am not supposed to. I am not perfect:/

Hi ToYoungToFeelThisOld. Do you have nail fungus or nail psoriasis? I have nail psoriasis and can't find anything that works. Thanks for your help.
