I’ve never encountered anyone who had a ”proper” theory on the detangling process. Here are my thoughts…
Since it seems the front of your hair is weaker by nature and seems to take the most abuse from handling and environment, I try to spare it. It’s not something I put a lot of effort into, but I have just made it a habit.
For my morning detangling, after unbraiding, I separate my hair in two using my fingers. It gets a bit crooked and isn’t very accurate since I separate it where it feels the easiest.
Then I start combing it out. I start in the back and work myself up/forward. My reasoning for this is that when you have detangled a knot, you have also semi-detangled the neighbour hair.
That way when starting in the back and moving forwards and up, the front parts are almost already detangled and have very little resistance when I comb it through.
It might seem like a ridiculously small thing to do, but I believe if you make it a habit and do it every single day, it saves you a lot of handling damage in time.
Let’s say doing this tiny little move “costs” your weaker front hairline just 20 seconds less handling in a day. In one year that adds up to a little over 2 hours of combing.
Not bad for a silly little thing that just comes down to a habit?
