Why would you concider Elasticity and porosity before styling hair?

Elasticity and porosity are crucial factors to consider before styling hair because they directly affect how hair responds to products and heat. Elasticity indicates how well hair can stretch and return to its original shape, influencing its ability to hold styles. Porosity determines how well hair absorbs moisture and products, impacting the effectiveness of styling techniques and the longevity of the style. Understanding these properties helps in selecting the right products and methods to achieve desired results without causing damage.
