"Also" is four letters, so even the length-based guides (AP, APA, AMA) would capitalize it. The only words those guides lowercase by length are prepositions and conjunctions.

"Also" in Sentence Case

APA reference lists, many news sites, and most UI text use sentence case instead of title case. There, only the first word and proper nouns get capitals, so "also" is lowercase unless it starts the title: "Why short words also matter." Pick one of the two styles for a whole set of headings rather than mixing them.
