Which of the following should be avoided to maintain healthy hair?

Regular trims
Heat styling without protection
Hydrating treatments
Using sulfate-free shampoos

The correct answer is: Heat styling without protection

Heat styling without proper protection can lead to significant damage to the hair. High temperatures from tools such as blow dryers, flat irons, and curling wands can strip moisture from the hair, weaken the hair shaft, and ultimately lead to breakage, frizz, and split ends. When heat is applied directly to the hair without a barrier, such as a heat protectant spray or serum, the risk of thermal damage increases, making it crucial to protect the hair when using these styling methods. On the other hand, regular trims help to remove split ends and maintain the overall health and appearance of hair. Hydrating treatments provide moisture and nourishment, combating dryness. Using sulfate-free shampoos is gentler on the hair and helps preserve natural oils, promoting healthier hair in the long run. These practices work to support and maintain hair integrity, contrasting with the detrimental effects of unprotected heat styling.
