color is a phenomenon when the dye in the clothes absorbes light, the molecule becomes excited to a higher energy level, back to ground state, and a different color light is emmitted. \n\nI'm thinking since the color just looks "darker" without any change in the spectrum. that means you only get a decrease in intensity (fewer photons). so water may have a quenching effect for the flourescence of the dye when it's close to the dye molecule. that way many emmitted photon is quickly quenched by the water molecule and fewer are allowed to escape and be seen so the color looks darker.

Likely not cosmetics unless it's causing an allergic reaction-if that were the case, you'd likely have some symptoms, dryness, peeling, inflammation, etc. \n\nLook to your ethnicity. Mediterreans, African Americans etc have more melanin in the skin (one of the things melanin does is give color) and as one grows older, these changes do seem to occur. \n\nThis information comes from just being around for a while and being a person of color myself as well as being a medical professional. \n\nIf you are of a lighter skinned ethnicity and the darkness is significant, a visit to a dermatologist may give you a better answer.

It is possible that the color of the water absorbed by the plant could tint the leaves darker than the leaves would be if the plant absorbed clear, colorless water.  This might effect the growth rate.\n\nAlso, the color of the water could be due to a chemical that affects growth rate, so in this case, yes the rate could be affected.

No, it will not make you sick. Your skin may absorb some f the dye but it won't harm you. They're supposed to be non-toxic.

my own understanding to this is - and i might be wrong - it has an affect. i based this on Albinos, they lack pegimintation (melinen) in their skin and eyes (which gives them pink or red eye colour) and they have major eye-sight problems and sun can affect them alot. so i would assume the less pigement u have (i.e. blue) the greater affect u will have by sun (even if it is very little) but surely there is a difference.

No, it shouldnt cause you to grow more white hairs. If you continually dye your hair, you just might not realize how much white hair you have until you grow it out. But it doesnt mean your hair dye caused it.\nTrust me...I dye my hair ALL the time! :) \nYou should be safe unless you have any allergies etc.\nCheers Girl! :)

Some people have claimed this, but to my knowledge no research has found any corelation between hair color and intelligence.\n\nAlthough some research has found that hair color can influence social relations, so people might treat a blond as being ditzy, but the blond would still have the same average intelligence as anyone else

There are certain things about your situation you didn't mention, like what is the natural ethnicity of your skin colour. Its cold hearted to suggest asking Michael Jackson, who has never darkened his skin and remains a mystery how it was lightened in the first place (he claims to have vitiligo which looks much different than what he is suggesting). You are obviously troubled by this. Tanning, if your skin has the ability now, is unsafe as there is risk of skin cancer developing. See a hair dresser about hair colour and see a doctor about your skin condition. I wouldn't take a pill that claims to alter hair colour. Hydroquinone is not available in some countries due to cancer risk factors.

Personally, I wouldn't worry about it. Don't, I repeat, DO NOT dye your hair! If it's healthy enough to have that long, dying it will ruin it, as you said. And don't cut it! Take pride in your hair! You've obviously cared for it to have it that long, so don't ruin it now. And you are not an "OLD gal" so don't even THINK it! If you are so terribly concerned about those three grey hairs, pull them out. You will go grey eventually, everyone does, but don't worry about it. Your hair is healthy, so it should grey gracefully and beautifully!

stress and old age. \n\nHair typically turns gray as a result of aging. Pigment in the hair shaft comes from special cells at the root (base) of the hair. These cells are genetically programmed to make a certain amount of pigment (melanin) at specific ages. At some point in the aging process, these cells make less and less pigment until the hair has very little pigment. White hair has no pigment, and gray hair has some but not as much as a red, black or brown hair.\n\nNot all hairs respond in the same way or at the same time. So the graying process usually is gradual. You can't prevent graying. Some people start graying in their 30s, and some not until their 60s. Genetics likely play a strong role in graying.\n\nPeople rarely go gray overnight. If they do, it's typically due to alopecia areata. This condition causes the thicker, darker hairs to stop growing before it affects the growth of gray hairs — giving the impression of graying overnight. Alopecia areata eventually causes roundish patches of hair loss or complete loss of hair on the head or body. Its cause isn't known.

hi there! greetings!,\nwell, the favorite color of somebody depends on the color of the person and sometimes the mood of the person. in reality the color plays an important role in your life. when you are wearing  certain color that really affects your mood for the rest of the day.And that even depends on the feelings,there are persons who really feel somewhat comfortable in certain color, cause of the heat absorption. and othere certain affects.one must select the color very carefully, cause it really indicates ones personality! on the others and the favorite color of mines is black ^ white^red^-----depending the mood!.\nthanks

Hello Dear,please reject some of the stupid answers.I will try to give you the exact answer. First,the hair pigments can be fading and then again working,so stop bothering about some grey hairs right now.Of vital importance is how you shampoo and condition your hair and what you must take as supplements.You mentioned that your hair is thinning,I strongly recomment you to use the best( as per my experience) brand Phyto..Use their great shampoo Phytocyane,containing Gingko Biloba,Grapeseed Procyanidins etc(bear in mind that the pigmentation of the hair will be regain with that stong anti-oxidant formula of that revitalizing shampoo)..To "boost" you hair grouth,strenght and energy apply 2 ampules a week of Phytocyane ampules for women..They work fine..I can tell you a bunch of too expensive supplements for hair,but again work great Pantogar(also is against white hairs) and Revalid,you may seek for them in the nearest pharmacy..Best of luck!!

Previous answer was close.  The hair follicle does not die, just the pigment cells that produce melanin, the chemical that gives hair it's color. As the hair has fewer cells producing melanin, the color becomes less pronounced, until it turns gray.

I did know it was unsafe, that is why when I colored my hair at about 3 months PG, I had the hair stylist just color my hair from right above the root down. That way no dye ever touched my scalp or my skin.
