Excessive heat and what it does to your hair
Hair is a very resilient structure with incredible strength properties. In fact, the tensile strength of human hair is greater than that of the steel rope that holds the Queensferry Crossing Bridge up.

But, just like steel can lose its strength if it’s not maintained, so can hair. There are lots of mechanical factors that can cause damage to the structure of your hair, from the wrong combs and brushes to the electrical equipment you use; the heat of the dryer, curling wand or straighteners, and dry heat from central heating, or intense sunshine, all can cause loss of moisture and protein from the hair.
Hair needs moisture to give it flexibility, bounce, softness, and shine. Protein gives hair its strength, the ability to be moulded into shape with heat and retain it, to give volume and body and to help prevent breakage.

If you imagine your hair structure inside is like rope, and just like rope it is made up of lots of tiny strands coiled together to create a strong structure. However, rope can unravel and then it becomes weaker. The tiny protein bonds in human hair can break down because of excessive heat, aggressive brushing and by using the wrong products. As the bonds break down the structure becomes weaker and more prone to breakage, split ends, and damage. Alongside that, the moisture can escape leaving hair dull and lifeless.

Once upon a time, damage was deemed irreversible, and the only option would be to have your hair cut off and to start again. Not now though, the products that are available for you to enjoy in salon and at home are so advanced that the tiny keratin (protein) bonds can be rebuilt, and the moisture can be replaced and locked into the deepest parts of your hair. This means that even the most damaged head of hair can be improved drastically.
