Maybe you have short strands or aren’t concerned about dry hair, and you just need a solid multi-purpose soap. Well, after 71 years, it’s still tough to beat Dr. Bronner’s. This workhorse eco-friendly hygiene product can be used for hair, body, dishes, clothes, and everything in between—and it’s equally effective in every scenario (from cutting bacon grease to getting the grime off skin). Plus, it comes in nice, not-harsh scents like lavender and even scent-free, which is always recommended for camping. The formula is famously concentrated, which means even the 2-ounce bottle will last a decent amount of time and that you should follow directions to dilute it.
