      @aleksandraanya9559 7 років тому +17

      It can be just from nail polish. Or if you're a smoker, it can be from that, too. Try filing just a small patch of yellow on your nail and if it comes off and underneath it's white you're good and it's just nail polish stains. Don't file too much though, that can really damage your nails.

    Btw just so people know if you use dark pigmented nail polish and don't use a non-yellowing base coat you can see the tips of your nails change colors. As long as your cuticle growth (new nail growth) doesn't look yellow you should be fine, but start using a proper base coat to prevent yellowing.

      +Steven Wills I never dropped a brick on my toes but once when I came home I was in a bad mood and slammed the door shut behind me a little too fast so the tip of my index finger got squished. I didn't even feel anything for the first 5 minutes or so (as in, it felt like my finger ended just before the nail), after that it hurt like hell and the whole nail turned blue. On the positive side, I got to know how fast my nails grow since I could just follow the old dried blood as it moved along with the growing nail.

  • @Idasmurf
    @Idasmurf 8 років тому +84

    Adding in that yellow nails can be completely healthy, repeated wear of nail polish and especially darker colors stain the nail and that is not a problem at all. So if you wear nail polish a lot and your nails are yellow then you probably don't have to worry.

    This is so interesting! Everyone should watch this to possibly detect health issues early. Being able to able to spot issues like infection, lack of oxygen, skin disorders, diseases, and cancer just from certain characteristics of your nails is incredible and should be more of a common knowledge to people. Nails and their trends tend to be overlooked or flat out ignored. This video helps enlighten people that maybe they should be more observant of it. It's not like it would be difficult to actually glance at your nails ever so often and take in mind the changes in them. One never knows what small thing could benefit them in the future. This video proves that everything has a reason and in this case that reason isn't just for decoration.

    I got Beau's lines from my chemotherapy last year (unsurprisingly, since of course the chemo targets and kills fast-growing cells, and can't differentiate between fast-growing cells that are supposed to be that way and ones that aren't; it's why you lose your hair as well). Very evenly spaced (as were the treatments themselves), very regular, one for each course of treatment.
    Eventually they grew out, of course, but it was neat to see. Happened on all of my nails. I was lucky, actually; most people lose at least a couple nails from chemo when the matrix and nail bed die, and I didn't lose any; just got the lines.
    --Incidentally, we caught it in time, my treatment went well, and so far as we can tell I'm all good. :)

    Watching this video makes me very concerned with the health of my nails because I have the bad habit of biting my nails constantly. It was very fasinating to learn about how nails grow and all the medical issues such as Beau's nails, Pitted nails, Raynaud's disease, onychomycosis and subungual melanoma can be caused by the unhealthy care providing to ones nails. Not only will the bad conditions of nails, but these conditions can cause further medical issues such as asthma, eczema, emphysema and lymphatic system. This video was very educated and is wanting me to start making a change in the way I treat my nails by preventing myself from biting them as much as I do.

    The lines you discussed first are really interesting. I kicked a door hard enough that my nail 'died' and turned an ugly purple color. It slowly loosened and fell off about a month later, revealing a smaller, bright red nail like a fresh layer of skin after you peel off a scab. About three weeks after that one of those lines appeared in that same nail. I've been panicking, but now I know it was just a result of the same injury. :)

    Certain shoes can also affect your nails-like steel toes boots or ballet slippers. I still have a nail that just kinda builds up super thick ‘cause stuff dies under it from when I had to wear steel toed boots years ago (and occationally it all just peels away from what’s growing underneath. My brother still works a job that requires steel toed boots so all his nails are just like that.)
    I also had my feet get waaayyy too cold with mild frostbite I think. Killed all my nails. Most have recovered, but it’s been a decade and I still have a nail with a permanent divot all the way from root to end with this kinda flaking area at the root where it just stops growing onto…despite the rest of the nail being a normal pink
    (And my raynauds doesn’t really seem to affect my nail growth. My fingers and toes turn red to bluish then bright red and puffy or marbled, but my skin and nails are otherwise normal looking)

      +whyareyoulookingatme
      It probably has someting to do with chemicals/minerals that make up the paint seeping down between the layers of nail plates, changing its color and/or refractive index. Maybe a thicker/harder transparent lacquer applied before the actual color is applied could help. It might seal the nail enough that the paint can't get between the plates.

    • @nithia
      @nithia 9 років тому +1

      +whyareyoulookingatme Your nails are getting stained. It is the same for ink or smoking. Paint, ink, smoking, and anything with strong pigment or a large concentration of small particles can soak into your skin as well as your nails, and the more of it that is allowed to soak in the darker the staining will appear to be as well as the longer it will take to fade away. If you are using a nail polish that tends to stain your nails try using a different brand, applying less, or applying less often. It is concentration and exposure time that affects this so trying different kinds of polish to find one that does not stain may mean that they kind you were using contains the right kind of concentration, or your nails may be more sensitive. As a guy, I have only worn nail polish about 3 times in my life, and the one time that I tried black polish, that did stain my nails. So I blame the polish first until you try some different kinds.
      As far as lighter or paler I cant explain that based on the polish. The only thing I can help with there is the remover may be having that effect, and darker or thicker polish requires more remover. So that could be the reason for that.

    I have had a red ring on all my nails for two year's now. My daughter died December 12th two years ago exactly. I found her. My mind snapped, for lack of a better word. I couldn't eat for the first year. I have custody of her daughter and need to be here to keep her safe. So I drank ensure, which is loaded with vitamins and I obviously lived, if you call that living. A friend said the first year is the easiest because you're in shock and denial. No truer words have ever been spoken. I was drifting away and finally agreed to try an anti-depressant. I've been on it for about six months now and I've started eating and being more active, but I still have the red rings and my hair is still falling out. I thought this would stop with eating healthy and taking my vitamins, plus being active, but there's no change. I've shown four different doctor's and non have done tests or have a clue what is happening. Please, if anyone has any idea what this could be, please say so. Her baby girl is five years old and when I say she needs me, she really does. It's literally a case of life or death if her father is allowed back in her life. Please. Thank you.

      This means you need vitamin B. I used to have white spots, but after a few months of eating more vitamin B rich food and drinks I do not have white spots anymore.

      No deficiency or so called Calcium deposits cause that thing. It can be due to some sort of repeated injury or nail biting.

      They are basically the same thing as a wrinkle like what you get from aging. The matrix of the nail atrophies over time just like your skin and this causes the height of the segments of your nails to be variable.

      That's calcium build up. Don't not worry it's perfectly healthy. It list means you nail matrix was having a high calcium flow when those particular cells were being formed😃😃
