Whether you have long, short, thick, thin, curly, or straight hair, you want it to look, smell, and feel clean. Most conventional brands leave your hair laden with proteins and residues instead of providing that clean, healthy sheen. For unconventional, natural cleansing, try Terressentials. Or be green and reduce waste by opting for a solid shampoo like the ones Lush sells; one bar saves three 250ml bottles.
