“This book claims to bust some myths about fungal nail and it really does that. I feel I had been misinformed with the more 'home remedy' and 'quick fix promise' focused books written by non-scientists or medical professionals on this topic. In contrast, this is a credible book written by a PhD scientific expert and covers the basics of nail fungus first. not an easy thing to treat but this book goes through all the strategies currently available to tackle it at home or with a medical professional. Highly recommend.”
