Nail Structure

The only reference to claws in humans tends to be a reference of romantic entanglement gone wrong. But in fact, human fingernails were derived from claws many millions of years ago. Claws, hooves and fingernails are made primarily of keratin. The fingernail itself has two layers and is attached to the skin at the matrix. The visible part of the matrix is the white crescent shape at the base of the nail on the thumb. It can sometimes be visible on other fingers, and may not be visible at all on the pinky finger.

Nails grow continuously throughout life. The key to nail growth is the nail matrix. It is where keratinocytes work to produce keratin. The fingernails themselves are layers of dead cells mixed with keratin. The new keratin slowly pushes the dead cells out from the nail bed, resulting in fingernails.

The shape of fingernails is related to the shape of the bone underneath the finger and blood supply or trauma to the finger. As the nail grows out from the matrix, it flattens and hardens. Nutrition and overall health status also affect the nail shape. Ridges, lines and discolorations can result from malnutrition or nutrient deficiencies. A study done in carpenters vs. office workers showed a greater flattening of nails in the carpenters. A similar study was done in jazz bassists and showed comparative results. The fingernails of the most commonly used fingers were flatter than the lesser used fingers. The studies support the theory that increased trauma and circulation to the nail, results in greater extent of flattening.

Fingernails grow at a rate of 3mm per month. Summer months and activity that increases blood circulation to the hand may slightly increase the growth rate. Poor nutrition or illness can result in slowed growth.Toenails grow at about half the rate of fingernails.

 

Nails Nutrition

Fingernails can be one of the most obvious signs of nutritional status. Adequate protein, micronutrients and fatty acids are critical for healthy nails and continued nail growth. Fingernails are made from keratin which is produced from amino acids . Amino acids are found in high protein sources. Protein found naturally in foods is the easiest form of protein to absorb.

We may color our nails so much that is can be hard to remember what a natural healthy nail should look like. The visual appearance of healthy nails are smooth nails with a pinkish nail bed. A white crescent shape at the end of the nail without any discoloration should be visible. The dermal layers surrounding the nail should be intact without redness or cuticle breaks. The end of the nails should have a smooth white edge without any breaks or layers visible.

Dieting that results in too little protein or limited fatty acids can result in brittle nails. The body will conserve essential fats and shunt them away from fingernails resulting in weak and broken nails. Other nutrient deficiencies can happen with other diet imbalances including excessive glucose, too much alcohol or a vitamin deficiency. Eating a well balanced diet and taking a nutricosmetic supplement are good tips for optimum nail health. 

Daily Nail Care Tips

Nails require good nutrition to maintain optimum appearance. Adequate protein and fatty acid intake are crucial for building keratin and maintaining moisture to prevent brittle nails. There has been very little proven to actually increase nail growth, however protecting existing nails and reducing breakage can give the illusion of improved nail growth. Below are some nail care tips for beautiful and strong nails. The American Academy of Dermatology Association has some additional tips at their website

  • Trim nails straight across regularly
  • File any hanging broken nail edges
  • Maintain adequate protein and vitamin intake
  • If on a low-fat diet, make sure to eat enough fatty acids for healthy nails
  • Avoid using acetone polish remover
  • Avoid removing nail tips without professional help
  • Do not pick at cuticles, instead try a cuticle oil or lotion at bedtime
  • Avoid buying nails or biting cuticles
  • Be careful of putting harsh chemicals on the nails, such as household cleaners
  • Wear gloves when hand-washing dishes
  • Wear shoes that fit properly
  • Avoid digging out an ingrown finger or toenail
  • Wear shoes in public showers to avoid picking up any fungus which can transmit into your nails
