The following outlines a process for applying solid shampoo products. This involves wetting the hair thoroughly, then directly applying the solid product to the scalp and hair roots, creating a lather. The lather is then worked through the hair, similar to liquid shampoo. Rinsing completes the process.
Solid shampoo offers potential benefits including reduced plastic consumption and travel-friendliness. Historically, soap-based hair cleansing bars were common, with modern formulations often incorporating milder surfactants and conditioning agents. The concentrated form contributes to its environmental advantages, reducing water content and packaging waste.
