Kitsch

Yes. A Kitsch bar lathers and rinses like a gentle liquid shampoo, and the formulas are free of sulfates, parabens, silicones and phthalates and pH balanced. The brand rates one bar as replacing about two bottles of liquid shampoo or conditioner, and its rice water bars at up to 100 washes. If you are switching from a silicone-heavy shampoo, the first few washes can feel different while that build-up rinses out.

Match the bar to what your hair is doing. Castor Oil is the everyday nourishing one. Coconut Oil suits dry or damaged hair. Rice Water is the strengthening, volume-building option. Rosemary and Biotin is the volumising bar for fine hair. Purple Toning is for blonde, grey, white or highlighted hair that is going brassy. Tea Tree and Mint clarifies an oily scalp. Ultra Sensitive is fragrance free. Each one has a matching conditioner bar.

Keep it out of the direct spray and let it dry between washes. A self-draining soap dish or a mesh bar bag gives the bar airflow on all sides, which is the single biggest thing that decides whether you get a couple of months out of it or a couple of weeks. Both are in this range.

Yes. The bars are pH balanced and the brand states they are safe for colour-treated hair. The Purple Toning Shampoo and Conditioner Bars go further, and are made specifically for blonde, grey, white and highlighted hair to neutralise brassy and yellow tones.

The bars are vegan and cruelty free, and much of the range carries Leaping Bunny certification. The bars are made in the USA from globally sourced ingredients. Certifications differ product by product, so check the individual product page for the one you are buying.

Invisible and Transparent suit most hair colours and leave no cast. Dark Tinted is the one for dark brown and black hair, because it blends in rather than leaving a grey film. All three are non-aerosol pumps, so there is no butane or propane in them, and they travel without the pressurised can.

The hair perfumes are made for hair alone. The Hair and Body Perfume Mists are the same idea in a formula you can also wear on skin. Both use odour-neutralising molecules rather than simply covering a smell, which is why people reach for them between washes or after the gym.

Satin is a weave, not a fibre, so it gives you the same smooth, low-friction surface as silk at a fraction of the price and it machine washes. Kitsch satin is OEKO-TEX certified. The smooth surface is why satin scrunchies, headbands and flexi rods tug less than cotton elastics or rough fabric.
