I have sinus problem since 2018.i caught cold 2 days back when I applied diy hair serum at night.is it not advisable to use diy hair serum or hair mask if you have sinus problem?

A. Maam depending upon first of all what ingredients are you using and if it is something which you keep in the head triggers your sinus issues then you should not use anything because at the end of the day it would completely depend on the severity of the sinus that you have
