Relaxer Stretch

Ever since starting my hair care journey the biggest change in my hair care regimen is stretching my relaxers.  I've tried super long stretches, like 20 weeks worth of stretching but I've come to like going about 10-12 weeks only.  Back when I didn't know any better, I would relax every 5-6 weeks.  Can you imagine that?  Sometimes I would do what's called a 'halo' which is just relaxing the edges and I'd do that as soon as there was a kink in sight.  I'm surprised I even still have hair.

So ladies, how often do you relax your hair?
