Making the switch from bottled products to plastic free shampoo and conditioner is one of the best swaps you can make in your journey to zero waste. Not only can it save you money, but as the products are made with natural ingredients and are free from nasties such as SLS and parabens, they should actually leave your hair in better shape!
The Soul & Soap shampoo bar range in particular are one of my favourite swaps. There is no transition phase with these shampoo bars so you shouldn't need a vinegar rinse. If you need any help making the final decision on the solid shampoo bars, just drop me a message on live chat.
