From personal experience I know my hair (thick in density and thick as and in some places thicker than thread) is no longer a pleasure but a burden if natural past BSL.
Texlaxed to a looser texture it's not an issue because it is straight and tangle free wet then dries to big Diana Ross hair.
I can get the best of both worlds.
Using chemicals as a tool I can have my cake and eat it too.
Do I think it would be impossible for me to take care of my hair natural at WL or beyond? No.
Do I want to invest the TIME, ENERGY, and MONEY (in products) to do it when texlaxed my hair requires 25% of the effort for 100% of the benefit...uhm...no.
Hair's hair to me relaxed, texlaxed, natural, locked, what-have you. I just want to grow mine out and do all the lovely styles I did before I BCed, whatever my hair's chemical state.
Bottom line:
It came down to how much effort I wanted to put into having long hair.
Thankfully I have the knowledge THANKS TO LHCF to take care of it no matter what the chemical state to get what I want as easily and quickly as possible.
