The Patchouli scents of our shampoo bars are reminiscent of the unique Scottish environment that inspired them. It turns out the spirit is good for more than just your spirit. Because a good single malt is so rich in antioxidants, adding it to our shampoos and conditioners promotes healthy hair and provides glorious hydration and sheen. Hamish & Co.™ shampoo bars are sulfate-free, paraben-free, phthalates-free, pH balanced, natural, 100% vegan, plastic-free, sustainable, cruelty-free, and ethically sourced. And sure, it’s whisky, but not for drinking. Save that for the pub. Safe for use on human hair extensions and wigs.
