I came across this article here about maintaining your pixie once you get it cut. Most of the information I do agree with, although I don’t recommend any of the products listed, only because I don’t use any of them! In my personal regimen, I use Elasta QP Glaze or Mizani Silk Defining Gel for a pomade. I use Keracare Moisturizing Hydrating Creme for my daily moisturizer, I seal with either Natural Coconut Oil or one of my pomades. I use Keracare’s Hydrating Detangling Shampoo(as well as most of their products). I definitely DO NOT get my hair relaxed(NO PART OF IT) every 2 or 4 weeks. I get a full head relaxer every 6 weeks. When my hair was longer that timeframe was every 10-12 weeks.
It is up to you if you choose to relax your perimeter every couple of weeks, I just think for me and my hair, that is way too soon. However, most people who tell me they do relax their edges that often get their hair cut w/electric clippers. My stylist only cuts w/scissors, so maybe that makes a difference? Happy Styling!
