alcohol is generally used in hair care to give a product good drying characteristics e.g. a pump hairspray based on
alcohol will dry much faster than one based on water. this is where the misconception comes in that alcohol is drying
so it must be bad for the skin or hair. if you think about it logically all that happens is that the alcohol evaporates off
because it is volatile (lower boiling point than water). as it evaporates it leaves behind any material dissolved in it e.g.
hair fixative resin in the case of a hairspray as well as any other conditioning materials that may be incorporated in the
product. think about what happens when you boil a solution of salt water - the water evaporates leaving the salt behind.
putting it simply alcohol is generally used as a carrier and would not have a drying effect on hair.
