Hmmm I'd think you'd notice even a little difference if it needed it.
Maybe due to heat damage they will take a while to start showing their curl again. I know my ends were incredibly straight for the first few weeks of going CG because I flat ironed them all the time prior. They still aren't as wavy/curly as my canopy or regrowth but they are getting better. I have been thinking about doing a BC for a whole now.
Maybe doing a DT too to see if anything helps? Mine really perked up after that as well. You might have better luck posing your question in the 4 forum too. I'd just ask about your ends and see if anyone else has a similar problem and they might have posted under a different phrase.
I know that heat damage recovery can take a while for some wavies and curlies so don't fret!
