Back in 2011, switching to shampoo bars was the first real step I took towards a low waste life. Here's an affordable shampoo bar, nice for greasy hair, with a wonderful scent of lavender and rosemary.This shampoo bar is free of palm oil, perfume, SLS and SLES.A medium size will last you the equivalent of 4 shampoo bottles while a small one is half the size.Tip: the medium sized bar can be a bit too big for small hands but you can easily cut it into two.
