Your fingernails grow untill you die.Your hair grows untill you die.Your fingernails grow untill you die.

Fingernails, hair and ears are the only body part that show considerable constancy of growth untill the moment of death.

Though many people assume that the nose grows until beyond the age of retirement, the Handbook of normal physical measurements describes that by fact with age the nasal bridge rises producing a more prominent root – which implicates that the nose is not growing much beyond age 18!

Some facts reported by the Telegraph about fingernail & ear growth are:

“The actual rate of nail growth one may (or may not) be interested to learn is 0.123mm a day. But what is remarkable is its staggering constancy over many years – almost as if the nails were aware of the higher purpose they are intended to serve.”

“The only other body part (besides the hair) that shows a similar constancy of growth in adulthood are the ears. They increase in size by the same amount in a year as the nail does in a day. This compensates for the gradual age-related decline in hearing – and accounts for why those in their seventies and eighties have apparently oversized ears. Who says there is not a Designer?”

Fingernail measurement.

In 1941 Dr. William Bennett Bean started his study on nail growth. His investigation began back in 1941 when he filed a horizontal line just above the cuticle and then measured its stately progress up the fingernail.

The American physician subsequently published his findings – once (incorrectly) described as the most boring scientific study ever undertaken – as “Nail growth: 35 years of investigation”.

The actual rate of growth one may (or may not) be interested to learn is 0.123mm a day. But what is remarkable is its staggering constancy over many years – almost as if the nails were aware of the higher purpose they are intended to serve.

The growth slowed remarkably when Dr Bean was laid low by mumps, but compensated by doubling its speed for the following six months. Disease and trauma might be expected to have an adverse effect, but not so: the nails accelerate as if to “grow out” the damage – a fifth as fast again in regular nail-biters.

The only other body part (besides the hair) that shows a similar constancy of growth in adulthood are the ears. They increase in size by the same amount in a year as the nail does in a day.

A milestone in William Bean’s nail growth research concerns his 1963 paper:

‘A Discourse on Nail Growth and Unusual Fingernails’

10 Skin & fingernail tips for men!

THE TOP 10 SKIN & FINGERNAIL TIPS FOR MEN!

– 1 –
Do not bite your fingernails. Fingernail biting can break the skin, spread germs to your mouth and hands, and lead to infections. Trim nails with a nail clipper, instead!”

“Use a skin toner, like aftershave lotion, to reduce the size of your pores. This will help keep your skin looking younger and healthier!”

Structure of your fingernail: the nail matrix attaches the finger with the nail plate.

The matrix is an ‘invisible’ part of the fingernail – but nevertheless it’s the most important aspect of the nail because nails grow form the matrix!

The process of a growing nail can be described as follows:

Fingernails are composed largely of keratin – a hardened protein which is also present in your skin and hair! As new cells grow in the nail matrix, the older cells are ‘pushed out’, compacted, and take on the familiar flattened, hardened form of the fingernail.

In An Atlas of DISEASES OF THE NAIL the ‘matrix’ is described as follows:


“The matrix of the nail the germinative epithelium from which the nail is derived. There is controversy about whether the nail bed and nail fold contribute cells to the substance of the nail plate. Regardless of this, the matrix is responsible for the majority of the nail plate substance.

The proximal portion of the matrix lies beneath the nail folds and the distal curved edge can usually be seen through the nail plate as the white lunula. The proximal matrix forms the superfiscial portion of the nail plate and the distal matrix makes the undersurface of the nail plate.”

NOTICE: The so-called ‘root’ of the nail is also known as the germinal matrix.
