What do the figures 15UL, 45UL, and 60UL represent?

The figures 15UL, 45UL, and 60UL are actually designations related to units of Lye used in the process of electrolysis. Each of these figures indicates a different concentration or strength of lye, which corresponds to various hair types during treatment. Lye is utilized in electrolysis to effectively remove hair by breaking down the protein structure, and the concentration needs to be matched appropriately to the thickness and coarseness of the hair being treated.

Understanding this relationship helps in choosing the correct concentration for effective hair removal and ensuring client safety and comfort throughout the electrolysis procedure.
