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.
Photosynthesis involves a chemical change.
no physical change is ptting ice cream and milk and mixing it for a milkshake or burning a piece of paper.

Yes it is chemical because the sun is producing food by causing chemicals and substances
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Physical changes
Growing of plants involve many chemical reactions.
Is chemicals from plants chemical weathering or physical weathering
No, plants decaying is a chemical change because the process involves the breakdown of organic compounds within the plant material into simpler substances. This chemical decomposition results in the formation of new compounds, rather than just a rearrangement of existing particles, which is characteristic of a physical change.
Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!
