Reviewers commonly report rapid and sustained reductions in dandruff and scalp itch, an overall improvement in scalp condition, and effective cleansing or clarifying action.
Typical sizes include 8 fl oz and 16 fl oz, with some products also available in 12 fl oz containers.
Some tea tree sprays are marketed as daily leave-in spritzes for areas like the scalp, behind the ears and the neck to freshen, detangle or provide topical benefits.
