Question

which hygiene practice has both social and health benefits?
coloring hair
brushing teeth
wearing deodorant
disposing of toxins

Explanation:

Coloring hair is mainly a cosmetic choice. Brushing teeth helps prevent oral - health issues like cavities and gum disease, and also gives fresh breath which is socially beneficial. Wearing deodorant controls body odor, improving social interactions and also helps in maintaining skin hygiene. Disposing of toxins is more of an environmental - health practice. Brushing teeth and wearing deodorant are more directly related to personal hygiene with both social and health benefits, but wearing deodorant is more focused on social acceptability due to odor control while brushing teeth has significant oral - health benefits along with social benefits from fresh breath.
