How come people have really deformed finger nails?

some problems are brought on from wearing fake nails nad not getting them done correctly.  Females go through alot to be beautiful and do not take in to account the side effects of some of the crap they do. You have to let your natural nails breathe and wearing the fake ones all the time will make the real ones soft, brittle and look really sick.  I still have one that grows wierd from wearing them.

No,that is an impossible reason..There's a condition,usually genetic(that is when is transmitted from genaration to genaration),which cause those nasty inproper grow of the nails..See a good specialist,because in the long run you may experience nasty outcomes if neglected..Good luck!!!

It depends on what you are referring to.  There are some conditions that will change the color, shape or consistency of your fingernails (psoriasis and emphysemia to name a couple) and then there are the things that are more like a fungus.  If you are having other health problems that are causing changes in your fingernails, seek immediate medical attention for the problem.  If you have something like a fungus, there are some over-the-counter remedies as well as prescription medications that may help.  You will need to use these remedies for a long period of time, however, because the root of these types of problems usually start in the nail bed and it will take a good 6 months to grow out the nail so it won't look all discolored and gross anymore.  If you get your nails done or paint them on a regual basis, stop doing that until the fungus clears up.

Try eating more Jello. Believe it or not, Jello or foods with geletin in it helps nails become more healthy. I play guitar with the nails of my right hand and learned of this and use it myself to strengthen my nails to withstand the stresses guitar strings put on my nails.

Because they've done it ever since they were children; maybe they grew out of the sucking thumb phase and started biting their nails. Other people do it when they're nervous or anxious. Some people do it to trim their nails, seriously! I used to bite my nails out of habit. Then I stopped doing it out of habit and just bit them when they got really long. I think long nails on a guy looks kind of feminine. I've never gotten used to using nail trimmers except for toe nails and nail files are uncomfotable and take so long unless you get a really good file, if there is such a thing.

I also bit my fingernails until well past the age of 40.  The only thing that made me stop that disgusting habit was to look closely at my nails when I was out in public.  Everyone I seemed to notice had beautiful, manicured nails and mine were stubs.  I did everything to hide them, but it's pretty hard to hide your hands.  I purchased a clear polish, and every time I thought about biting I would polish instead.  You have to combine that with the sheer willpower that you want your hands to look "presentable!"  Today my nails are strong and beautifully shaped, and I think of what I missed all those years by "nibbling" all the time!  Now I don't have to put my hands in my pockets...I'm proud of my nails and want everyone to see them!  Good luck.  You can do it!

Each finger has its own distinctive mark. So, the answer is they are different.

My only answer to this one is the fact that they get nervous. I used to have a habit of biting my nails, but soon stopped because it is gross and you can get infections from it. I don't necessarily think that people "eat" them. Chewing is maybe something they do and it is a disgusting habit. \nI know that it is most likely a nervous habit.

It's not that only your fingers and toes wrinkle, but they do so more easily.\n\nInevitably, a nice long soak in a bathtub sloughs off the excess sebum from your epidermis. As a result, your skin starts to take on water. The top layer of the epidermis is known as the stratum corneum, which is Latin for "horny layer." These are the tough, dead skin cells that are constantly being sloughed off your body in your clothes, your bed, and in the form of dandruff. Disturbing, but true. \n\nYour fingers and toes have especially thick layers of stratum corneum. Once deprived of sebum, they swell up with water, causing wrinkles.

Some people bite their nails simply as a bad habit and they have to consciously make the effort to stop.\n\nOther people, the ones who get down to bare bleeding skin, may be suffering from depression or something similar.  I used to be this person, I was biting my nails down to the nubbins to (unconciously) cause myself physical pain in order to cover up emotional pain.  After spending some time in therapy I was able to find better ways of dealing with things and now I have lovely nails!\n\nBy the way, this second example of nail chewing is a very similar behavior to people who cut or otherwise hurt themselves... the physical pain is easier to deal with than emotional pain.

Sometimes it's related to nutrition, sometimes to stress (called Beau's lines, I believe), sometimes to external wear such as buffing or filing. \n\nAre your nails healthy looking or are they yellow or green? Lifting in places? These would indicate fungus.\n\nHave you changed your supplements in the past few months? \nPeople sometimes  get a ridge when  start loading on biotin after taking a break (forgetting) for a few months. Have you been buffing them lately? If you are, that would be my first guess unless they're yellow or green.\n\nOTHER CHANGES TO MAKE  HEALTHY NAILS\n\n- drink pure, clean water (6-8 glasses a day)\n- avoid drinking alcohol\n- avoid saturated fats and fried foods they stress the liver\n- eat high fiber diet (brown rice,millet , and legumes are good)\n- make sure to get vitamin A, C, and E - try a good quality multi vit/mineral supplement\n- reduced sugar, candy, etc...\n- avoid caffeine, hydrogenated oils, fried foods, meat, soft drinks\n- reduce dairy products in your diet\n- for healthy nails make sure you are getting enough protein\n- keep nails shorter \n- do not cut your cuticles

Because we have muscles on both sides of our fingers - or rather, tendons.  Our legs and our arms are the same way.  In order to extend our fingers or to clench our fingers, we have to use opposite muscles in order to do so.  When we relax BOTH sets of muscles, we end up in the middle, and hence, our fingers take on a curved look.

I used to think this too, I crack my finger knuckles all the time!  Here's a little medical myth's debunked info for ya!

Feet are bumped, banged, stepped on, and smushed more often as they are on the ground and used for transportation.  Nails (on fingers and toes) are protective devices (the way a helmet is used to protect your head).  Makes sense for toenails to be thicker and stronger, because feet take more abuse in general.

You may not be eating the right foods - you need plenty of calcium for healthy nails and teeth. You may also need some zinc. Or, it could be the way you are filing them - don't use a metal nail file, as this can tear the nails. Don't file right down the sides of your nails, as this will weaken them. When you shape them, keep them rounded, not too pointed, as the shape will keep them stronger. If you tend towards dry skin, use handcream, or make your hands damp and dab vaseline over them (this traps the moisture in, rather than keeping the moisture out and is much less expensive than handcream). Try wearing clear nail varnish, this will help strengthen your nails, and don't chew off your nail varnish as this takes away some of the top layer of your nail. I think that's all I know about fingernails!

Most likely the hair on the toes is remnants from our less evolved ancestors. Since toes, and fingers for that matter, are small and out in the open, they are highly susceptible to the elements, especially cold.  So, to fight the cold on our tiny appendages, we had little tufts of hair.  Hair is a natural way to help the body trap in heat (why do you think people shave their heads in the summer).  However, it is also likely that our ancestors had a lot more hair on their hands and feet, and thus their fingers and toes.  We didn't evolve from apes, but they do have a lot of hair don't they?

You either have a rare genetic defect or you have a fungal infection in the nailbeds. Check with your dermatologist.
