Yes overconditioning is possible too. I was having some awful hair days until I added in a cream styler. Rusk being Gutsy or Loreal out of bed, or boots, recoil on some of the days. I used Gutsy today and my hair is real curly. It's overcast here and 60 during the day.
Boy I hate it when I have to play guess why my hair is acting up. I always go scrambling until it finally calms down again. I take those bad hair days seriously! After all there's a big ole mirror in the bathroom
2c/3a?
