What ingredient helps protect hair from heat damage during styling?

Heat protectant is specifically formulated to create a barrier between the hair and heat sources, such as blow dryers, curling irons, and flat irons. These products typically contain ingredients that can withstand high temperatures and reduce the risk of moisture loss and structural damage to the hair shaft. When applied before heat styling, heat protectants work to minimize the adverse effects that high temperatures can have, such as brittleness, split ends, and overall hair deterioration.

The other choices, while they serve important functions, do not specifically target heat protection. Sulfates are often found in shampoos and can strip moisture from the hair. Moisturizers are beneficial for keeping hair hydrated but do not provide protection against heat. Detanglers help to ease combing and reduce breakage but do not offer any thermal protection. Therefore, heat protectants are vital for anyone who regularly styles their hair with heat, ensuring it remains healthy and resilient.
