Listen to the chords. Harmonic minor scale will not work over i-iv-v progression but if you replace the v with a V7 chord, it will work. And that's because the dominant chord has a major third which is the 7th note of the harmonic minor scale. For example in A minor it will be G# that is the third of E major chord (dominant chord of A minor). Harmonic minor scale will work over progressions (in minor) that have the V (dominant) chord.

And you are really using the notes in the chromatic scale every time you play an accidental. Nobody's just playing the chromatic scale up and down. But most solos use some chromatic notes.
