I was told a week before your relaxer to stop, and a week after to start.....I didn't do that and started using a growth aid like 2 days after my relaxer....and it's already growing......i know a good thing right, but I'm trying to stretch for 4 months, and if my hair is already growing, then in 4 months, I wont be able to do nothing with my hair, and I will have a lot more shedding.....but it's actually your choice....good luck finding your answer!
