Why does your hair appear longer when it is wet?

Possibly if you have curly hair, when it is wet it is straighter, and when you blow dry it, or whatever it bunches up?

I don't think that's normal.  All the older girls I know have a full head of hair.  Some of them may turn white but they don't lose hair other than your normal hairfall in the shower.  You may have alopecia. Or it could be a symptom of something else. Go check with your doctor.

When water falls, it becomes a mist. Then light refraction occurs and the wave length changes. It looks white because it scatters the light. I also creates rainbows because of the light refraction.

The reason for it to get darker is because when it absorbes water it fills up little micoscopics air caveties and ones is does this it absorbes more light, therefor it looks darker. (is doen't change its color, just looks like it)

Some people think it's because the skin expands to allow extra water inside. The expanded skin ends up looking really wrinkly. Other people think that it's because the skin is tied down to the tissue underneath in certain places. So when the skin is full of water, it swells up (gets puffy), but only in places where it is not tied down, which makes it look wrinkly.

because when it is wet, more of the particles stick.

It's drier in the winter.  The moisture level is way lower simply because it's colder.  And since moisture deters static charges, you get more static electricity in your hair when you brush it in the winter!

Your skin has a limited capacity for keeping water out. \nAfter a long bath, your skin will absorb some water, and will tend to expand its surface. However, due to the lack of space for expansion, it gets wrinckled.

It should tone down a bit after several days.  It's probably just the excess dye in your hair.

You don't, it just doesn't evaporate like it would in non-humid conditions.  Its all about the movement of water, and if the air is already very dense with water particles (ie. humidity) then the liquid on your skin is less inclined to enter the air.  But in very dry conditions, the water on your skin evaporates quickly and this cools you down.

If you stay in the water TOO LONG then your skin is obviously going to because you've deepend the D.N.A lines\nToo much science stuff to understand? Ask your local neighbour!

I'm not for sure but I think it is the way that it grows or maybe the fine little hairs that grow on them. This site might help you more than I could.

You have two different types of bodily hair.  One is called terminal and the other is called vellus.  Terminal hair is the longer growing hair that is on your head, legs and things like that.  So, to answer why do they keep growing it is bc of the type of hair it is.  The vellus hair doesn't know how long it is....it only grows to a certain length according to your own body type.  I hope this helped a little bit

Hair does get lighter naturally with sunlight... we all know that.  The heat of a blowdryer can dry hair out and fade it, making it appear lighter.

when you shave your hairs the reason they come back darker and thicker is that, the part that wasn't cut will begin to grow and since it is already thick at the base it will grow up and look thicker than the previous hair. reason y it is longer i don't really remember but i heard that the more you shave the faster it grows back and longer it become.

Spring or fall  - If its in the summer, you might have tan lines and in the winter the extra cold is kind of a shock (you lose a lot of heat through your head with out the hair there)\n\n---In response to the person below - it can actually heat you more in the summer.  With the sun beating down on you without at least a little hair there, your head will actually heat more.
