Which product is essential for prepping hair before heat styling?

Using a heat protectant before styling hair is vital for several reasons. Heat styling tools such as flat irons, curling wands, and blow dryers can reach high temperatures that may damage hair if it is not properly protected. A heat protectant product forms a barrier over the hair strands, reducing moisture loss and minimizing the risk of damage caused by direct heat exposure. It often contains ingredients designed to withstand heat, ensuring that the hair remains healthy, shiny, and resilient after styling.

While a detangler can help manage knots and make hair more manageable, it does not provide the protective qualities that heat protectants offer. Hairspray, on the other hand, is typically used after styling to hold the hair in place and does not serve a purpose in protecting hair during the heat application process. Leave-in conditioners moisturize hair and can assist in detangling, but they do not specifically address the risks associated with heat styling. Thus, the heat protectant stands out as the essential product for preparing hair before applying heat.
