I voted six months, because I've had some products not work in certain kinds of weather and I'm not the kind who's willing to swap out products acccording to season. I can't keep it all straight. A product must work year-round to be a HG to me.

My HGs:
  • - Jessicurl RR
    - Jessicurl CCSS
    - Jessicurl HCC
    - Ojon RT
    - Elucence MB Condish
    - vinegar+h2o
    - homemade scalp massage oil: jojoba with tea tree oil and peppermint e.o. [this replaced my former HG of Aveda's Balancing Infusion]
    - pink Boots [but I don't use it currently, since it's kinda hard to get]
I think CurlKeeper might be added to this list. I just ordered my second bottled of it from CurlMart, so we'll see.

I'm a 3a/b, coarse and thick, BTW.
