Conditioner Bars

Conditioner bars are the natural companion to a shampoo bar routine, and in some ways, the more immediately satisfying one. Where a shampoo bar takes a few weeks for hair to fully adjust to, a conditioner bar tends to deliver results from the very first wash.

The bars in this section are syndet conditioner bars, built around BTMS-50 rather than soap or silicones. They condition without coating, which is a distinction that’s hard to describe until you feel it. After the very first wash, my hair felt like…my hair….not like hair-coated-in-product.

This category is newer than the shampoo bar section and will grow as recipes are tested and results are confirmed. Everything published here has been made and used, not just formulated on paper.

The beginner conditioner bar recipe is the foundation — one tested formula with every ingredient explained and the process documented in full.

If you’re using both a shampoo bar and a conditioner bar for the first time, change one thing at a time. Start with the shampoo bar and add the conditioner bar once your hair has settled. Isolating variables makes troubleshooting much easier.
