I added a few drops of rosemary essential oil to hair products and massaged into scalp. Lots of collagen supplements, I used the powder in smoothies and mixed into any liquid. Other supplements: Diatomaceous earth, Horsetail, any of the nail/skin/hair supplements, drink green tea. But even with all of that my experience is it runs it's course after 2-3 months so focus on growing back. Mine came back but somewhat unevenly.
