Follicle cells in your scalp assemble proteins to build new hair. this most likely involves reactions.

Dehydration Synthesis Reaction

Explanation:

When water participates in a reaction as a product, the process is called a dehydration synthesis reaction, since atoms of H and O are removed from the molecule, which join together to form a water molecule. This occurs at the bonds between amino acids to form proteins. This also occurs when a cell gathers its proteins to create a structure in the body, an example of this occurs when the follicular cells of the scalp gather proteins to create new hair.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
