Partial nail avultion--how long does a pna take to heal?

Finger or toe? Nails take time to grow out. Toenails grow out slower than fingernails. Average toenail growth rate is about 1.5 mm/month compared to fingernail growth rate of about 3.5 mm/month. The big toenail grows faster than other toenails & the little fingernail grows slower than other fingernails. Hope this helps.
