Why wait until next month! I recently started my second set. The first time I tried (3 months ago) I got it done "professionally" but didn't really like how it was done. I did it myself a couple nights ago and so far I like it a lot. I've always don't my own hair and it just felt right to keep that going as I begin this journey. However, everyone's experience is different and I'm sure you'd be happy with either decision.
