Using the patches
How long does nail regrowth take? A realistic timeline
The single biggest cause of disappointment with any nail routine is expecting the nail you already have to change. It will not, you are waiting on the nail that has not grown yet.
Days 1-3: settling in
You are learning the routine: clean nail, flat file, patch on before bed, patch off in the morning. Nothing visible changes yet.
Week 1-2: consistency
The habit is the point. Skipped nights are the usual reason people see nothing at the four-week mark.
Week 3: pack complete
Twenty-one patches take you to the end of the pack. Any change is at the cuticle end, the discoloured nail further forward has to grow out.
Month 2-12: regrowth
Fingernails replace themselves in roughly three to six months, toenails in nine to twelve. Big toenails are always slowest. Take a photo at the start so you have something to compare against.
