Hair that has the largest diameter and usually requires more processing time is:
- A.
Fine hair texture
- B.
Coarse hair texture
- C.
Medium hair texture
- D.
Gray hair
Correct Answer
B. Coarse hair textureExplanation
Coarse hair texture refers to hair that has a larger diameter compared to fine or medium hair. This larger diameter makes the hair strands thicker and stronger. Because of its thickness, coarse hair usually requires more processing time, such as styling or chemical treatments, compared to finer hair textures. This is because the thicker strands take longer to absorb and react to the products or processes being applied.

A. StapHylococciExplanation
A carbuncle is an inflammation of the subcutaneous tissue, commonly caused by staphylococci bacteria. Staphylococci are a type of bacteria that can enter the body through a cut or wound and cause an infection. They can multiply rapidly, leading to the formation of a carbuncle, which is a painful, pus-filled lump. Other options like mites, nits, and headlice do not typically cause carbuncles.Rate this question:
