All-natural vocal sprays like Clyor might be great for comforting the voice, but they are no substitute for correct technique. They are not magic pills. There is no substitute for singing properly and the best tip to keep your voice healthy is to sing constantly! Don’t go more than 2 days without singing, as singing (properly) keeps the muscles loose.
As for singing properly, one thing I can offer here – always place your notes from above, never come from below or think up to the note.
