Swapping a bottle of liquid shampoo for a solid bar is a small change with an outsized effect on what's rattling around your shower shelf, and this Black Castor Oil Shampoo Bar makes that switch straightforward. Formulated with black castor oil, jojoba oil, and olive oil, the 60g bar is built to cleanse and condition in a single step rather than asking you to reach for two separate products.
The bar comes in packs of one, two, or three, so you can try a single bar before committing to a larger supply, or stock up if solid formats already work for your routine. Because there's no bottle involved, it slips easily into a wash bag or carry-on without the spill risk that comes with conventional shampoo, and it stores just as easily at home on a draining dish.
Using it is close to using a bar of soap on your hair. Wet your hair and scalp thoroughly, then work the bar directly between your hands or glide it gently along wet strands until it starts to lather. From there, massage the lather through your scalp and hair the way you would a liquid shampoo, then rinse thoroughly. The supplier's own estimate is 40 to 50 washes per bar, though how far a bar actually stretches depends on hair length, how often you wash, and how much product you use each time - treat that figure as a general guide rather than a guarantee.
Between washes, the bar benefits from a little care of its own: set it on a draining dish rather than leaving it in standing water, since a bar that stays wet softens and wears down faster than one that's allowed to dry. That one habit does more for how long a bar lasts than almost anything else.
