(Update: I created a clearer, more detailed video showing how to retigten your own loc here)
The first step is making a homemade sisterlock tool instead of purchasing the traditional sisterlock tool or the nappyloc tool (which comes highly recommended and is pictured below):
I want to warn against the heat, I ruined two needles with the fire step. The third came out perfectly fine without the heat.
My current loctician explained that I am a pattern 3 and after some research I want to continue with a 3, which yields a looser, fuller and fluffier looking lock. These videos were a great help to me:
A post from a professional helped me to visualize sisterlock pattern three aka 9, 6, 9, 12 (as in the face of a clock).
Dreadlock Journey advises to:
Always enter the loc at the scalp. As you pull your loc through, always push loop down towards the loc to eliminate gaps in your lock. Repeat until you are at the scalp and cannot complete another rotation. Your retightening should resemble a fishtail and feel like a tight cord.Thus far I have re-tightened 5 locks successfully but wanted to share this post in the interim!
Disclaimer: When I can afford to splurge, I do plan on taking the official re-tightening course! I will continue to see my Consultant and this does not replace the invaluable guidance a seasoned professional can provide.
