How does a hairdryer dry wet hair?
When you plug in the hair dryer and turn the switch it on, the electrical current flows through the hair dryer. The circuit first supplies power to the heating element. In most hair dryers this is a bare coiled wire, but in models that are more expensive there can be fancier materials in action, like a tourmaline-infused ceramic coating. The current then makes the small electric motor spin and that turns the fan. The airflow generated by the fan is directed down the barrel of the hairdryer, over and through the heating element. As the air flows over and through the heated element, the generated heat warms the air by forced convection. The hot air streams out the end of the barrel. The hairdryer uses a small fan that looks like a hydraulic turbine (i.e. water wheel). The fan in a hair dryer uses electrical energy to generate airflow. The small motor actually sits inside the fan, which is firmly attached to the tip of the motor. When you supply power to the motor, the motor and the attached fan both spin. The centrifugal movement of the fan blades draws air in through the small round air inlets in the side casing of the hair dryer. These holes are covered by a safety screen that prevents other objects (such as strands of your hair) from being sucked in as well. The air is then blown down the barrel of the hair dryer. When you use it on your hair this hot air blows the water, or chases it, off the hair shaft. Imagine the hair is like glass. Water runs straight off of it.

Thanks for the feedback!
You can wet the hair first before rolling it into perm rods or you can simply squirt each section about to be rolled with a water bottle in order to dampen it. The hair defini…tely needs to be dampened to effectively roll it onto the rods.
Hair should be dry when coloring it. Any moisture left in the hair will dilute the color and affect the desired results.
The general rule is that hair color should be applied to DRY hair, as wet hair will dilute the hair color mixture. Only on occasion should color be applied to wet hair, …IE. When toning at the shampoo bowl immediately following a bleaching service.
Either. Obviously if the hair's dry, the rollers need to be hot. If you're rolling your hair while it's wet, they don't have to be. And although rolling your hair when it's we…t takes a long time to dry, the curls turn out better looking and tend to last longer.
Do it while the hair is wet. You can also put the rinse in your conditioner and apply it that way. It will save you time from applying each step separately.
you wet your hair first
Because its being weighed down. When its wet it has more weight, so it pulls on your scalp. This pulls the hair and the roots, which makes it longer. Wet hair is at its most …vulnerable state when wet and can stretch up to 30% which is why it is best to detangle gently and to take into consideration when cutting wet hair.
If you are using non-heated rollers, then it is fine to put rollers in your hair while it is wet.
I'd have to say that if you have damp hair it works fairly well, and you still have time to fix those little glitches before it dries and hardens.
Physical cause it hasn't changed its just gone from wet to dry :-)
you put rollers on wet hair because when it drys it has more bounce
Wet, because it's easier for the hair to "cooperate" under the scissors. Dry haircuts don't come out well and your hair can go "bonkers". It is true......There is more control… when the hair is wet, but when texturizing, hair should be dry.
Dry, because when you put the dye in your hair will get wet.
No, there is no change at all to you hair. _____________ This is not a chemical change, but a physical change instead.
I have an amazing set of 'Wet to Dry hair Straighteners'. They are Remington S7902. My hairdresser told me about them, and i now love them! They are currently half price in …boots and superdrug at the moment. £39.99 in Boots, £29.99 in Superdrug.
Electricity is converted partially in to heat by means of a heating element built in the dryer. Another part of electricity is converted to a circular motion of an electri…c motor with a fan, which forces the hot air out of the hairdryer.
