It is generally acceptable to touch your own scalp. You might do so to scratch an itch, adjust your hair, or simply to feel the texture of your scalp. There is no evidence that touching your scalp directly causes harm, although it's important to note that scratching vigorously can irritate the scalp.
However, touching someone else's scalp without their permission is generally considered inappropriate and potentially offensive. This is especially true if the person has a different racial or ethnic background. For example, asking to touch someone's hair because it is a different texture or style than your own can be seen as disrespectful and insensitive.
The act of touching someone else's scalp can also be seen as a violation of personal space. Even if the intention is not malicious, it's important to respect others' boundaries and avoid touching their bodies without their consent.
Remember, it's always best to err on the side of caution and ask for permission before touching someone else's scalp.
