Greendoor Orange Shampoo Bar, 75 g

Why it is on the list

A 75 g solid shampoo sold in a folding paper box, so it replaces a liquid shampoo bottle without plastic wrapping around the bar.

Watch out for

Solid bars need to dry between uses (a draining dish helps) and the listing quotes an orange-oil fragrance, which some people react to.

We have not physically tested these products. Our shortlist is research-based: we check what the listing says, favour non-plastic main materials and name the limits we can see. Always read the listing for sizes, certifications and care instructions.
