Final answer:
The answer is false. Cosmetologists do not need to work with every hair texture and hairstyle trend.
Step-by-step explanation:
The correct answer is False. While it is important for cosmetologists to be knowledgeable about various hair textures and hairstyles, it is not necessary for them to work with every single type and trend. Cosmetologists often specialize in specific areas or have expertise in certain hair types, such as curly hair or color treatments.
For example, a cosmetologist who specializes in working with curly hair may not have as much experience or knowledge in working with straight hair or other textures. In addition, hairstyle trends can vary greatly and change over time, so it's important for cosmetologists to stay up-to-date with current trends, but it is not a requirement for them to work with every single trend.
