If you can’t get away from straightening, curling, or blow-drying your hair, use a heat protectant spray before you style or blow dry to reduce the severity of damage. Any type of heat application on the hair will damage the hair but applying a heat protectant spray can help increase the longevity of the health within the hair when using heat-styling tools frequently.
So, how does heat protectant sprays work?
Editors from NewBeauty spoke with hairstylist and founder of Hair Room Service in New York, Michael Duenas, about heat protectant sprays. Duenas states that using a heat protectant spray can “’add moisture to your hair, preventing the natural moisture to evaporate.” The heat protectant spray can add and keep in moisture in the hair due to its ingredients. He suggest picking a heat protectant spray containing nourishing oils such as “obliphica Berry, argon nut oil, olive oil and/or coconut oil” for extra moisture. Duenas also mentions that the spray “’forms a protective barrier over the cuticle on the hair strand, preventing heat damage and enabling your hair to keep its high shine.’”
To add on, Michelle from Lab Muffin, gathered research on the effects that heat protectant sprays have on hair. She shares that PVP/DMAPA acrylates copolymer, quaternium 70, and hydrolyzed wheat protein are the three chemicals found in heat protectant sprays that “form thin films on the hair surface which slows down heat conduction and distributes heat more evenly.” These chemicals create less damage because it makes the hair “heat up gently rather than suddenly.”
Michelle also notes that the best results from using heat protectant sprays only “show 50% heat protection at most.” Although damage from heat cannot be 100% prevented, it is a good idea to use a heat protectant spray to reduce the damage.
