Most tea tree shampoos in this selection are formulated for a range of hair types, commonly labeled for normal and dry hair; some formulas are specifically marketed for color-treated hair.
Users commonly report a minty or tea-tree scent and a tingling or cooling scalp sensation. Many reviewers note a rapid reduction in flakes and itch with a refreshing feel, while a minority find the scent strong.
Several products pair tea tree with zinc pyrithione and cleansing agents (for example, olive oil) to help target yeast and microbes, reduce flaking and itch, and remove buildup.
Multiple formulas in this set are labeled sulfate-free and paraben-free; some also advertise being phthalate-free, dye-free, silicone-free, formaldehyde-free, and gluten-free.
Typical sizes in this selection include 6.8 fl oz, 8 fl oz, 12 fl oz, and 16 fl oz.
