I had nail fungus on most of my nails-over half of them. I had a problem years ago with only the thumb nail. This time it was really bad-I'd had artificial nails and I neglected them. When they were removed, my nails were absolutely gone-paper thin with fungus. After removal this continued to spread lower and lower. Over half of my nails had extensive fungus--apparent by the unattached white colored nails. Some were almost unattached all the way down to the "moon". From my other incident years ago I learned there is NO cure other than to cut away COMPLETELY ANY and ALL nail that isn't attached (debriding). I messed around with a thumbnail for over 2 years. Attended a doctor who game me Rx and told me to keep my nail dry-nearly impossible. Finally I got fed up and cut down the thumbnail all the way as far as I could. Knowing this, this time I cut back my nails completly all the way down as far as possible. This involved over half of most of them. Kind of hard on the eyes, but why screw around with all these liver damaging drugs, and soaking, and failures. Amazing! I marked the calendar: by the time 4 weeks had passed all of my nails had reached the point of where the natural quick is--except the 2 thumbnails-they're alot slower! It's been 6 weeks since I trimmed them all the way back. I did have to invest in some special clippers-"cuticle trimmers". Otherwise it would have been impossible to get rid of all the "white"with regular nail clippers. The clippers are about $14.00. Much better than Dr. bills, Rx's soaks, salves; Also much better than fooling around for weeks, months, and years. Generally for me, the smaller the nail, the faster the recovery. I would like to thank the manicurist on this site for her imput. She has been a manicurist for 19 years and her advice includes using clear iodine on your nails. This, she says makes the nails grow fast. I have a slow thyroid so the iodine thing is very intesting to me. The best part aobut ths whole thing is: Not only did my nails fill back in quickly, but now they are the strongest I've ever seen them! Almost every night I put the clear ("blanco") iodine on them. I'm not a doctor, but I would NEVER take any prescription drug that would damage the liver. That to me is unconsiousable. I am not a doctor and cannot advise others. All I wish to do is share how quickly this worked for me and how strong my nails are now! I'm very grateful!
