We are so grateful that hairdryers, curlers and straighteners exist. It gives us the chance to change up our look whenever we like and helps our hair look just how we want. What we don’t love is the impact of the heat on our hair if we don’t use heat protection sprays.
Why Bother With Heat Protection?
Every single on of our hair strands is coated with a protective layer called the cuticle. It is made up of cells that overlap each other like fish scales to help keep moisture in the hair and keep it smooth and shiny. The cuticle makes sure that the inside of our hair, the cortex, stays healthy. If it isn’t that is where we can start seeing breakage and hair loss.
Blow drying can cause a ‘flash dry‘ effect on the hair, removing not only the surface water we are trying to get rid of, but also water within the hair strands. This can cause the cuticle to become dry, rigid and brittle.
Straightening or curling can cause the cuticles to crack along the edges, making them prone to chipping and increasing the risk of water loss. If your hair is wet whilst you use them, then it can cause little tiny blisters along the cuticle from the water bursting out as steam. Both situations leave hair prone to breakage and looking dull.
So, heat protection is essential to keep hair shiny, smooth and healthy, limiting the chance of breakage and split ends.
