I've only used the liquid, too! CurlKeeper seems pretty runny from what I've seen, so I figured the liquid was closer to the "real thing" than the gel would be. Unfortunately, my dews are almost in the single digits right now and they all have glycerin, so I'm avoiding until spring. lol
2c/3a, fine, low porosity.
Poo: Garnier Fructis Pure Clean (yes, it has a mild sulfate, but I have Teflon hair)
Co-wash: VO5 Kiwi Lime Clarifying Conditioner
LI: GVPCB or Keratin Complex Vanilla Bean Deep Conditioner (nothing to do with keratin straightening, just a nice conditioner)
Style: KCCC + Pantene Curl Shaping Gel (winter) or LALSG (summer)
Dry: Diffuse or air dry, depends on my mood
