Are solid shampoo bars same as liquid shampoo?
Both solid and liquid shampoo can cleanse your hair and scalp – just a matter of how harsh they are! No problem!
One main difference is how they incorporate beneficial nutrients such as herbal extracts etc. Liquid shampoo can easily incorporate water soluble and easily absorbable nutrients such as fleece flower root, ginseng, ginger etc. These nutrients will be carried to your scalp and hair through the lathering process and be absorbed along with the water or moisture. But solid shampoo bars need to use oil-based contents. The surfactant or soap will react with these oils and carry them away likely leaving no trace on your hair and scalp. So, if you wish your shampoo to do more than cleansing, there is a difference between shampoo bar and liquid shampoo.
