how fast do nails grow? Enter the experts, please... How long
does it take nails to grow? And, how much faster do they grow on
the fingers? The old "rules of thumb" were: - Fingernails: 6-8
months to grow out fully Thumbnails 8-12 months to grow out
fully - Small toenails 12 months to grow out fully - Great
toenails 12-18 months to grow out fully Mr. William B. Bean
studied his own nail growth for 35 years and published the data
in Arch Intern Med, 1974, Vol. 134, 497-502 (30 yrs) and ibid,
1980, Vol. 140, p. 73-76 (35 yrs). He found that nails grow more
slowly with age; growth rate at age 32 was 0.123mm/day, but by
age 67 had decreased to0.095mm/day. No variation with
geographical location, physical activity, or season. Thumb nails
grow faster then the rest of the fingernails. Great toe nails
grow faster then other toenails. Toe nails grow slower then
fingernails. Umm.... Just like you thought!
