Hair (newly grown) is a product of many (bio)chemical synthesis reactions.
It is both a physical and chemical change.
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. :)
Added correction:It is chemical because you can not simply revert it (newly grown hair) back to its original compounds.Plants (newly grown) are product of many (bio)chemical synthesis reactions.It is much the same as growing animals or humans.
Growing taller. All the others are cosmetic changes.
Physical, it's not changing your hair into a different substance. Its still hair. To be chemical change you would have to light it on fire or something like that. Something that would change it into something new. Physical changes can always be changed back, like freezing water, it's still water, and will change back when heated or left out. Chemical changes are most always permanent, if you burn paper you arnt going to get that paper back. It's turned into an entirely new substance, ash and smoke
Growing of hair is a biological process that involves physical changes in the cells of the hair follicles. It is not classified as a chemical change because the structure of the hair remains the same as it grows.
It is both a physical and chemical change.
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.
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.
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. :)
I think it is a physical change Improvement: It's actually a series of chemical changes. As different chemicals are added they break and make bonds within the protein make-up of the hair.
