Tips to avoid an irritating rash

alright y'all, I just used Nair to take care of the forest that was my vagina. 
then, I used my razor to hit some of the spots that I missed. 
after I got out of the shower I applied Cetaphil lotion to the parts I shaved to avoid any sort of irritation, but I feel like it won't be enough. 
y'all got any tips to help me avoid any sort of burning, itching, and irritation?
