Final answer:
Shaving is the most common form of temporary hair removal, commonly achieved using various types of shaving creams to ease the process. Chemical depilatories, such as those from Nair and Veet, work by chemically breaking down hair structure and are also widely used. The correct option is 1.
Step-by-step explanation:
The most common form of temporary hair removal is shaving. Shaving and trimming take away the part of the hair that is above the surface of the skin. When it comes to chemical depilatories, such as gels, creams, lotions, aerosols, roll-ons, and powders, they work by breaking the disulfide bonds within the hair's keratin, weakening the hair structure so it can be easily removed. Common brands include Nair, Magic Shave and Veet. For example, chemical depilatories often contain calcium thioglycolate and maintain a high pH level to effectively dissolve hair without damaging the dermal papilla, which means the hair will eventually grow back. Shaving creams, which come in various forms like aerosol shaving foam or lathering creams, serve to soften and lubricate the hair for a closer shave.
