DIRECTIONS

For best results use daily or as directed by your doctor. Work up a lather using warm water and gently massage into affected areas. Soap should stay in contact with affected skin for 60-90 seconds. Rinse well. Use on affected skin or scalp in place of your regular soap or shampoo. In case of accidental ingestion, contact a physician or poison control center immediately. Rinse with water if soap comes into contact with your eyes (the zinc pyrithione will sting).

USE AS SHAMPOO

Castile soap is strong enough to clean the scalp of excess sebum and product build up, but gentle enough to not leave our hair stripped and dry. Experiment using the soap at different dilutions (e.g. 2 teaspoons and one cup water, etc.) until you find the right dilution for you. Many customers use the soap at full strength. Castile Soap is NOT as color safe as sulfate free shampoos. Soaps tend to be alkaline which means that they can open the hair cuticle and remove hair dye quicker.
