Our shampoo bar is enriched with probiotics which will accentuate the benefits of all the natural and valuable ingredients while cleansing your hair and scalp as well as balancing and boosting your hair & scalp microbiome and giving relief from an itchy irritated scalp, split ends, hair loss and dandruff. Our Probiotic shampoo bar is free of any harmful chemical such as synthetic surfactants. When you switch to our natural probiotic shampoo bar you may experience a period of cleansing where old chemical residues exit the hair and scalp. This can take up 4 or 5 washes. We recommend the use of our Probiotic Hair Conditioner along with the shampoo bar, especially for long hair.
