I think it works great for some people. Not me. My hair is extremely dense. I need to lightly finger detangle every day and do a thorough comb job once a week to remove shed hair. That kind of ps like you have makes my hair tangle with shed hair. I end up having to cut knots out when I take it down.
looks like its really working for you. i have wanted to do this for so long, though i dont have the time to spend 2 hours a day braiding my hair. so instead, due to the colder weather ive been bunning my hair every day. i change the position of the bun to mix it up a bit. i also use quiet a bit of oil to seal and help protect my hair from the weather. i think its been helping me. though you do show same great progress with your twist outs.
my hair: 3c, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
my hair goal length is bra strap length when curly.
