In an NIH study of 46,709 women, permanent hair dye was linked to higher breast cancer rates in Black women. That’s a link, not the cause. Plant powders colour hair without permanent-dye chemicals.

Brown: Light Mountain henna, medium brown, 3 × 4 oz
A makeup wipe can leave its preservatives, and sometimes fragrance, on your face with no rinse. Washable cotton rounds let you choose what touches your skin.
What you put on your skin and hair often stays there for hours. These swaps look at specific chemicals researchers have studied: TPHP in nail polish, benzene that turned up in some aerosol dry shampoo propellants, PFAS in long-wear makeup, and permanent hair dye chemicals. Several of the studies here show a link, not a cause, and each swap says so. The other thread is fragrance: US labels can list a whole scent formula as one word, and some of its ingredients cause skin allergies, so our picks have no added fragrance in the maker’s own ingredient list. Each swap names a pick that meets our written rules, or says when we haven’t found one yet.
