A lovely zero-waste alternative to bottled shampoo! Thanks to the balanced pH of 5- 5.5, this solid shampoo does not need an acid rinse and won’t have a transition phase! An acid pH of 4.5 to 5.5 is essential to prevent excessive dryness and hair damage during the cleansing process. Acid-balanced shampoos help close the hair cuticle and are recommended for hair that has been colour treated or lightened. Thanks to this pH, the shampoo reacts the same regardless of the hardness of your water. Take our solid shampoo with you instead of a regular plastic bottle. They last for months and as they are so small so they save you so much money and space and are earth-friendly, requiring minimal packaging. If you haven’t experienced a solid shampoo, try one, you’ll be glad you did.
