Is poly tar shampoo ok to use on permed hair?

Poly tar shampoo is generally not recommended for use on permed hair. Permed hair has already been chemically treated, and using a harsh shampoo like poly tar can further damage the hair and break down the perm. It is advisable to use mild, sulfate-free shampoos and conditioners specially designed for permed hair to maintain its health and style. Consult a hairstylist or beauty expert for specific product recommendations.
