I have a major headache and unfortunately this post will be lengthy so here goes --
I haven't read all posts so forgive me if it's a repeat. I know a thing a two about having tangly hair. I don't recall if you are natural or relaxed but I'm relaxed so here's what I found that works --
(1) Gently and quickly detangle by finger combing every few days because it speeds things up on poo day because you have less tangles to deal with.
(2) Separate hair is smaller sections because 4 sections were too large of an area. I now separate hair in 6-8 sections and temporarily clip hair with duckbill clips so that I can work with one section at a time.
(3) Saturate hair in an oil rather than water/condish mixture because those mixtures make my hair feel very stiff and the comb grips and tugs, thus causing breakage. Oil provides great slip. I think evoo or evco works great for detangling. Make sure you REALLY saturate hair very well -- that's the key.
(4) I quickly finger detangle to remove shed hairs one section at a time, then I use a very wide tooth comb to glide through the hair from tip to root. I don't spend much time detangling at this step because majority of the detangling comes while in the shower. Braid hair and secure with a barrette. When you're done, you will have 6-8 braids secured by barrettes.
(5) Don't disturb somewhat pre-detangled hair too much when pooing.
(6) I detangle while rinsing out DC. I unravel 1 braid, position head under shower so that this little section is all that's getting wet. I run comb through this area from tip to root to detangle while water is running over that area. If all the condish rinses out of this section before I'm fully detangled, the hair loses slip so I will STOP and apply a rinse out condish like Aussie Moist (great slip) to finish detangling this little section. When done with this section, I don't re-braid, I simply clip that section up with a duckbill clip.
(7) Repeat until done. Keep in mind, if you mistakenly rinse out some of your condish from other areas while rinsing a section...apply some rinse out condish before detangling or the hair will lose its slip.
Side note -- I find that ceramides are excellent for detangling (even better than evoo and evco) and provides softness to the hair. I now pre-detangle with wheat germ oil and add some hemp to my DC. I never knew what it felt like to have tangles melt out of hair....but now I do.
Ceramides is where it's at.
Mane and Tail Detangler is also good for adding a little extra umph to your detangling once you're out of the shower.
