Mostly a physical change. There's really no chemicals from a curling iron its self. Some people use special shampoos to curl their hair. I suggest using the curling iron if you want the curls to last a short time. The chemicals stay in for about a week, so if you want them daily, use the chemicals. But if your head is sensitive, then don't use it for too long.
Yes it is because when the microns, proteins, and the carbon fiber fuse together, the energy released heats your hair causing it to change shape.
you dont have to but it is best to as it protects you hair from getting damaged :)
curling iron
the four-in-one cortex curling iron! its a clampless iron with interchangeable heads. its a great investment. also you can try curling your hair with a flat iron. there are tons of videos to show you how to do so on the Internet.
Put the end of the clump of hair in between the scissor part of the iron. Then slowly twist with one hand on the handle and the other hand at the very end of the curling iron. Hold for a few seconds and release the pressure of the scissor.
Curling hair with hair rollers is a physical change because no new substances are being formed. The shape of the hair is being temporarily altered by the application of heat or by setting it in rollers, but the chemical composition of the hair remains the same.
Cutting hair and shampooing hair are purely physical changes. However curling or straightening hair involve chemical changes too (i.e. sulfur crosslinks move). Dyeing hair is also chemical.
It is both a physical and chemical change.
Curling your hair is a physical change because it does not alter the chemical makeup of the hair strands. It involves applying heat or using tools to change the shape of the hair temporarily, which can be reversed by washing or straightening the hair.
Chemical Change
Cutting hair is a physical change because it does not alter the chemical composition of the hair. The cutting process only changes the physical appearance and length of the hair without changing its chemical structure.
cutting your hair is probably a physical change I don't know
Bleaching your hair is a chemical process, not a physical property. The chemicals in hair bleach work to break down the natural pigments in your hair, resulting in a lighter color. This change is due to a chemical reaction rather than a physical characteristic of the hair itself.
No, the drying of wet hair is a physical change, not a chemical change. The change in state from wet to dry is due to the evaporation of water and does not involve any chemical reactions altering the composition of the hair.
Does your hair actually change when it's cut? No, so it's just a physical change from long to short.
Coloring hair is a chemical change because it involves a chemical reaction between the hair dye and the hair strands, altering the composition of the hair.
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
