Have you tried protein treatment? Detangle your hair in stages, like don't do it all in one sitting.My hair has gotten to a point where it's getting moisturized but it is just sooooo weak it comes out in clumps, especially in the nape area. The nape is the most fine. I was shocked. One thing my hair never was, despite it all, was weak. I'm not really upset to lose so much hair because I'm kind of over my hair - permanently - as I'm about to shave it all off, and I know it's really a matter of needing protein. Hard protein even, if it doesn't stop.
The tangles are soooo bad (worse than when I was natural because... idk why. It might be that its so tangled from that isoplus, at least I'm hoping that's what caused the dreaded up pieces all throughout,and not my curls just happening to behave that way now). It's hard because I have very little time or energy to do my hair and when every step takes hours... you do the math. I still don't know the nature of my new texture really, but I do know that I'm going to transition to fully straight because I don't think half textured is working for me. My hair is just too spongy. By nature it'll always shrink and tangle once dry if I don't go fully straight, and I have to decrease the tangling by any means necessary. I definitely will need regular protein then.
My hair is so uneven and damaged from detangling and hairloss that I just wanna shave it and wear wigs and perm my new growth every few months to transition to healthy, even fully relaxed hair. It would work for me because I can't reach a hair braider right now. I need to get my (possibly alopecia related) scalp issues worked out too, so shorter hair would help me apply medicine more easily too if need be.
I usually also rinse with conditioners (moisture/protein according to my hair) when I am doing prolonged detangles. It loosens the tangles and minimizes hair loss
