I'm one of the ones (maybe the only) that thinks it's sort of a waste. I had a lot of relaxed hair (9"-11") compared to natural hair while transitioning, and my relaxed hair soaked up a lot of product. I've spent probably $100-150 trying sample packs and products from Ashas, Oyin, My Honeychild, Qhemets, etc. and at least they're lasting me a while because my all natural hair isn't very long. YMMV.
The products I swore (and still do) by during my transition:
-Homemade moisture spritz (filtered water, molasses, aloe vera juice, glycerin, avocado/jojoba oil, sage, rosemary, peppermint EO)
-IC Fantasia Gel
-Jamaican mango & lime cactus leave-in
-Giovanni direct leave-in
-V05 Free Me Fresia or Blueberries & Cream with molasses/honey, EVOO, castor and/or vatika oil thrown in and heated. I also used a random mix of conditioners.
-Denman brush
-Flexirods
-Condition wash 1-2 times weekly.
