Hi all - just to let you all know I used a very good nail oil and varnishes while going through my chemo, radiotherapy and Herceptin treatment - I got it from foothealthfirst.com. It doesn’t have any of the damaging components of normal nail varnishes and the oil was a life-saver for me and I didn’t lose any. Just a tip from someone nearly at the end of this horrible journey. Love to all x
