Curly Nikki just posted about her Holy Grail products, and that prompted me to disclose mine here. What's interesting is how few I really have. I've been CG for more than two years now and this list -- a finely honed assortment that doesn't reveal any inkling of how many products I went through to find them -- is all I've got. Maybe some of yours are on this list, too?
Shampoo(s): never touch the stuff (well, okay, sometimes I reach for Jessicurl's Hair Cleansing Cream, but normally I just scrub with a palmful of Suave Naturals Coconut Conditioner)
Conditioner(s): I'm on my last bottle of Activate Hydrating Conditioner (pictured here among some companion products as a kind of memorial), which has yet to be replaced by anything else as my No. 1 favorite. The company no longer makes the stuff (or maybe the company is out of business; I don't know) and I will have to turn instead to any of these very nice conditioners: Mop Top Daily Conditioner, Aloeba, Aubrey Organics Island Naturals as well as GPB Conditioner, Karen's Body Beautiful Hair Nectar and the old version of EO's Rose and Chamomile (of which I have only two more bottles left).
Leave-in/Styler (s):I always use my regular conditioners as leave-ins and you already know what those are, so I'll just list stylers: Kinky-Curly Curling Custard is my absolute Holy Grail product, and yet I cannot use it by itself. In rainy weather, I mix it with Biosilk Rock Hard Gelee and for nice, normal dew points (35 to 55), I mix the KCCC with Max Green Alchemy Sculpting Gel. Sometimes Aubrey's B5 Design Gel alone or mixed with Mandarin Magic is nice. I've also been discovering Joico JoiWhip mousse lately -- it's not consistently great but when it's good, it's very very good.
Deep Conditioner (s): Several months ago, I decided that these are just silly. For me, anyway. My hair (3a, fine) doesn't need deep conditioning as much as it needs protein, so I combine the two in my daily conditioners and my hair is much happier.
