I put gum in my sister's hair.  I guess I should shave it all off, right?

It's best to avoid using physical removal methods, such as shaving, as this can cause more damage than the original issue. Instead, you should try a thorough hair cleanse with a clarifying shampoo, followed by deep conditioning to promote re-growth and strengthen any damage hair follicles.

It depends on the type of gum and your sister's hair. If the gum is not too sticky and it comes out with a normal comb, then you probably don't need to shave her hair off. However, if the gum has dried or stuck to her hair and you cannot get it out with a comb, then shaving her head may be the best option to get rid of it.
