I love that advice! My scalp burning was one of the reasons I turned to self-relaxing and no lye.@FadingDelilah I hear you. I've been a self relaxer for over 15 years now which is why I dont.
I also forgot to add in terms of vinger as a neutralizing step. When I did go to the salon for my relaxers, my stylist at the time would just pour undiluted white vinegar on the areas that were starting to burn which would allow the parts that still needed to process time. I still do that to this day. I pour vinger on and let it sit for 15 secs before rinsing. Also try to rinse your hair as much as possible before adding shampoo, I usually wait until I see no white suds/particles; I only need to shampoo twice this way
