True or False: Hair should be shampooed as often as necessary to maintain good condition.

The statement that hair should be shampooed as often as necessary to maintain good condition is true. Regular shampooing is essential for removing dirt, oil, pollution, and product build-up, which can contribute to unhealthy hair and scalp conditions. However, the frequency of shampooing can vary based on individual hair types and lifestyles.

For instance, people with oily hair might feel the need to shampoo more frequently, while those with dry or curly hair may require less frequent washes to avoid stripping natural oils. Therefore, while shampooing is important for maintaining good hair health, the specific frequency is often tailored to meet the unique needs of each individual's hair type and condition.

The other choices suggest limitations that do not fully encompass the idea that regular shampooing plays a critical role in hair care routines. Understanding the balance of cleansing without over-washing is key to maintaining healthy hair.
