Can I continue to cut my hair short while treating?

The light based treatment works by bathing your scalp in two wavelengths of light to help regenerate the cells that grow hair. Continue to cut your hair as you normally would for the style you want. Remember, the regenerated cells heal from the inside out and may take a few months to show new growth. You just want to avoid doing anything that might irritate your scalp or damage the skin while trying to renew it.
