There is never going to be a one size fits all sort of answer for quantity of product used BUT... For an average guest, I use about quarter size amount before the blowdry and add more if needed Good rule of thumb with creams and oils in general- only apply ponytail down and rake it through with your brush or fingers for even distribution 🙂 #chatterssalon #chattersbrampton #styleppy #hairproductknowledge
