I can't find a specific word for "head hair" in English, other than hair, which is the general term for hairs all around your body.

In many languages like French, Italian, Spanish, Portuguese, Russian....there's the word hair which can be used for everything (your scalp hair, your facial hair, your body hair, eyebrow hair...) BUT there's also a specific word for the hair on your head, though using hair is ok.
Those languages, like English, also have words to describe fine hair (vellus), or beard for the thick hair on your face, or eyebrows, etc... or also mane for a long mane of hair, or bun or ponytail...But when it comes to the physical thing, the strand of hair, lots of languages can use either "hair" or the other one (Cabello, Cheveux, Capello, etc....)
In shampoos for example, those countries never use the umbrella word hair. They always use the specific word, let's call it "Scalpstrand" in English. For example "for oily scalp strands" or for curly "scalp strands" or for blonde "scalp strands", etc...
I know it's a bit complicated for you English native speakers, hope you understand what I mean. I'd like to know if you always use hair.
Examples:
ITALIAN: Pelo (Hair, regardless of its location). Capello (Hair on your head).
SPANISH: Pelo (Hair, regardless of its location). Cabello (Hair on your head).
FRENCH: Poil (Hair, regardless of its location). Cheveux (Hair on your head).
PORTUGUESE: Pêlo (Hair, regardless of its location). Cabelo (Hair on your head).
RUSSIAN: Volosy (ВОЛОСЫ) (Hair, regardless of its location). Kabel'o (кабельо) (Hair on your head).
