It is both a physical and chemical change.
Hair (newly grown) is a product of many (bio)chemical synthesis reactions.
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. :)
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
the acids chemical reaction for hair dying is that your hair will blow up!
no it is a color dye added to the dead cells that are your hair.
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.
no you must dye it
It is both a physical and chemical change.
Dyeing your hair is bad for it regardless. What you can do is just dye over it with black or brown, or go to a professional & have the stylist lift the colour for you.
Bleaching your hair is chemical change
I would say about 6 monthes
Chemical Change
No, there is no change at all to you hair. _____________ This is not a chemical change, but a physical change instead.
Short answer is yes. Dying the hair involves a chemical process, which damages the hair. This causes the texture of the hair to change for a short while and it becomes dry, rough and often normally smooth hair will get knotty.
no it isn't a physical change it doesn't change the actual chemical properties of the hair
Yes.
