Final answer:
The traditional method of sugaring uses a thick paste applied against hair growth and removed in the direction of growth for hair removal. In contrast, chemical depilatories like calcium thioglycolate creams break down hair's structure for removal but do not target the hair's growth center.
Step-by-step explanation:
The method of sugaring in which the product is applied against the hair growth and removed in the direction of the hair growth is known as the traditional or manual technique. This method uses a thicker application of the sugaring paste, which adheres well to the hairs without attaching to the skin. To effectively use this technique, the paste is molded against the direction of hair growth and then quickly flicked away in the direction of hair growth, allowing for a less painful and more thorough hair removal process compared to other methods.
Chemical depilatories, another method for hair removal, operate on a different principle. These products typically contain 5-6% calcium thioglycolate within a cream base and utilize an alkaline pH maintained by calcium hydroxide or strontium hydroxide. The product breaks down the hair's structure by severing disulfide bonds in keratin, which allows the hair to be easily wiped away after approximately 10 minutes. However, unlike sugaring, this method involves a chemical reaction that does not target the dermal papilla, meaning hair will eventually grow back.
