Watch the Damage Heat Does To Your Hair in 5 Seconds

For those who have dyed your hair only to be shocked by how your colour has disappeared, it may be due to your heat styling products.

Guy Tang showed via YouTube and Instagram how an iron set can damage your hair. He also says that blowdrying under high heat and washing your hair in hot water can ruin hair colour as well.

Obviously, you would never hold your hair in a hair straightener for 5 seconds in one place but it goes to show how much damage it can do!
