All hair sprays contain alcohol and that can be very drying to hair. Subsequently that is its purpose. Hair Spray is used to freeze dry the hair. It closes the pores of the cuticle layers so the hair will not absorb any extra moisture from the environment. Curls will only fall during a humid day because hair strands absorbs the moisture from the environment and swell and become heavy. The weight of the hair loosens your curls or weighs the hair down.
A great suggestion is to find a product that is contains a lower level of alcohol such as Clairol professional Sheer Mist. This product holds style all day and protects hair from any weather condition. after using this product, the hair is touchable, flexible and shiny.
