I have a problem as we speak from wearing weaves, since it's a sewn in weave and my hair is braided, maybe I can help with some advice.
My hair is EXTRA dry after removing weaves and the condition of it looks bad. I currently have ATLEAST 5 inches of new growth and MAJOR strinkage from it being a cornrows (sewed in weave) for so long.
You have to be extremely careful when detangling your hair after removing the braids. I also get A LOT of shedding after I remove the weave and unbraid my hair because remember, you hair sheds like 100 hair per DAY alone. When it's in braids it has no place to go until you take out the braids. I expect now that when I run my fingers through my hair after taking out the cornrows to see shedding. Check the top of the hair shaft and see if there's a white bulb and make sure it isn't breakage. I actually check every strand and almost all are just shedding.
The last time my hair was out of the weave was on Oct 31, and it looked EXACTLY as it did when I first got it in (the end of August!!!)... which seems to makes no sense because I had 4 inches of new growth and if my hair was cornrows, how can it have broken off? Don't be fooled, it can easily be strinkage. I will be relaxing my hair in about 2 weeks, then flat ironing it to THEN assess it's true length.
Next time (if you braid again) detangle as MUCH as you can by HAND, then WIDE tooth comb. It's very tedious, but it's your hair! Trust me, I've experienced the WORSE tangles & even the worse MATTING, after taking out my weave. Believe it or not, I got out almost all the tangles with my hands. Adding water, conditioner, or shampoo, which your hair is weaker when wet, will make your already dry hair break.
From MY experiences, weaving & braiding do more harm then good.
