How did the steamer improve your moisture levels if your products didn’t absorb as well?
I'm not quite sure how to explain but I'll give it my best shot, and hope I dont sound like an idiot. Keep in mind that I'm a low porosity head, so the hard part is getting moisture in my hair. Retaining moisture is easier.
Steaming:
While using my steamer, my hair swelled and some conditioner would drip off my hair as opposed to melting into it. I'm low porosity, so my hair only absorbs so much. I'm assuming that when steaming, my hair absorbed more water than product. After all, the steam IS water, so you're essentially adding more water to your hair during the steaming process. Plus without a plastic cap, some conditioner will inevitably run off before it can be absorbed.
Once I'd get out from under the steamer my hair would look more plump but have less of a conditioned feel as compared heatcap/dryer deep conditioning. That doesn't sound good, but somehow it worked. My hair may not have felt as conditioned immediately after rinsing out the conditioner, but once I applied my leave ins I could see and feel the difference. For the first 6 weeks or so my hair improved after every steam, becoming less dry and more pliable. I stopped seeing improvement after that so I'm assuming I reached my max in moisture level.
Dry Heat+Plastic cap
When I DC under a heatcap or hooded dryer, the product seems to melt into my hair and the volume of my hair decreases (smoothing rather than swelling). I get more of a "conditioned" feel (smoothness, shine, and that slight film that a conditioner can leave behind). Maybe since the only water to absorb is from my shower damp hair and the water in the conditioner, there's more "room" in my hair cuticle for product. Also with a plastic cap on, the product cant drip off before absorbing.
Why do both?
Before I started steaming, my hair was dry and stiff. Even though I heat deep conditioned every wash and it initially felt conditioned, but once dry it was DRY. Steaming drastically improved my hair because it allowed me to get more water/moisture into it.
Since my moisture level was much better, when I went back to heatcap deep conditioning the experience was different. The conditioned feel I'd get immediately after washing, lasted much longer. Probably because I was maintaining that moisture level rather than trying to improve it.
When I buy a new steamer I plan to steam for the first month or so to improve my moisture levels again, then alternate between steam conditioning and dry heat conditioning, to maintain it.
