Fingernails and toenails are made of a tough protective protein called keratin. This protein is also found in the hooves and horns of different animals. It is made up of dead skin cells. Nail Care Tips:
The nail consists of:
• 1- the nail plate
• 2- the nail matrix
• 3- the nail bed below it
• 4- the grooves surrounding it.
A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries.
It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger.
The nail then acts as a counter-force when the end of the finger touches an object, thereby enhancing the sensitivity of the fingertip, even though there are no nerve endings in the nail itself.
Finally, the nail functions as a tool, enabling for instance a so-called “extended precision grip” (e.g. pulling out a splinter in one’s finger), and certain cutting or scraping actions.
Fingernails require three to six months to regrow completely, and toenails require twelve to eighteen months.
Actual growth rate is dependent upon age, sex, season, exercise level, diet, and hereditary factors.
The nail is often considered an impermeable barrier, but this is not true. In fact, it is much more permeable than the skin, and the composition of the nail includes 7–12% water.
This permeability has implications for penetration by harmful and medicinal substances; in particular cosmetics applied to the nails can pose a risk.
Nails can dry out, just like skin. They can also peel, break, and be infected.
Common organisms causing nail infections include yeasts and molds (particularly dermatophytes).

Take a close look at your fingernails. Are they strong and healthy looking? Or do you see ridges, dents, or areas of unusual color or shape? Many less than desirable nail conditions can be avoided through proper fingernail care. Others might indicate an underlying condition that needs attention.
Your fingernails — composed of laminated layers of a protein called keratin — grow from the area at the base of the nail under your cuticle.
Healthy fingernails are smooth, without pits or grooves. They’re uniform in color and consistency and free of spots or discoloration.
Sometimes fingernails develop harmless vertical ridges that run from the cuticle to the tip of the nail. Vertical ridges tend to become more prominent with age. Fingernails can also develop white lines or spots due to injury, but these eventually grow out with the nail.
Not all nail conditions are normal. Consult your doctor or dermatologist if you notice:
• Changes in nail color, such as discoloration of the entire nail or a dark streak under the nail
• Changes in nail shape, such as curled nails
• Thinning or thickening of the nails
• Separation of the nail from the surrounding skin
• Bleeding around the nails
• Swelling or pain around the nails

Fingernail care: What to do
• Keep fingernails dry and clean: This prevents bacteria from growing under your fingernails.
Repeated or prolonged contact with water can contribute to split fingernails.
Wear cotton-lined rubber gloves when washing dishes, cleaning or using harsh chemicals.
• Practice good nail hygiene: Use a sharp manicure scissors or clippers.
Trim your nails straight across, then round the tips in a gentle curve.
• Use moisturizer: When you use hand lotion, rub the lotion into your fingernails and cuticles, too.
• Apply a protective layer: Applying a nail hardener might help strengthen nails.
• Ask your doctor about biotin: Some research suggests that the nutritional supplement biotin might help strengthen weak or brittle fingernails.
Fingernail care: To prevent nail damage, don’t:
• Bite your fingernails or pick at your cuticles: These habits can damage the nail bed. Even a minor cut alongside your fingernail can allow bacteria or fungi to enter and cause an infection.
• Pull off hangnails: You might rip live tissue along with the hangnail. Instead, carefully clip off hangnails.
• Ignore problems: If you have a nail problem that doesn’t seem to go away on its own or is associated with other signs and symptoms, consult your doctor or dermatologist for an evaluation.
• Use harsh nail care products: Limit your use of nail polish remover.
When using nail polish remover, opt for an acetone-free formula.
Care if you visit manicures and pedicures (nail care)
Manicures (for the hands) and pedicures (for the feet) are health and cosmetic procedures to groom, trim, and paint the nails and manage calluses.
They require various tools such as: cuticle scissors, nail scissors, nail clippers, and nail files. Artificial nails can also be fixed onto real nails for cosmetic purposes.
If you rely on manicures or pedicures for healthy looking nails, keep a few things in mind:
• Stick to salons that display a current state license, and work only with technicians also licensed by the state board.
• Don’t have your cuticles removed — it can lead to nail infection.
• Also, make sure your nail technician properly sterilizes all tools used during your procedure to prevent the spread of infection.
