Updated edition of 93's natural tea tree oil shampoo / body wash. The updated formula includes a higher concentration of tea tree and is sulfate-free. Like the previous issue, these bottles are 12oz each (with updated packaging and improved formula). Carefully tested, developed, and bottled in the USA. No added coloring or dyes. No animal testing. No added fragrances (the shampoo has a pleasant and natural tea tree oil scent, but no artificial odors added).
