Barra de Champô de Coco - D R Harris London

The lather this bar whips up is genuinely impressive — a tiny amount goes a long way, so I can see this tin lasting months. It's also nice not worrying about plastic bottles in the shower anymore, and the metal case keeps it tidy for weekend trips.

I've been taking this bar on every trip since I got it—the metal tin keeps everything dry in my toiletry bag, and one bar has lasted me months of daily use. It's the rare solid shampoo that actually feels like it cleans without leaving that waxy residue.

The lather really is voluminous—a tiny twist on the bar covers my whole head, and the aluminium tin means it survives a week in my gym bag without turning to mush. It rinses out clean and leaves my hair feeling soft, not stripped.
