Of course mostly I will use my hands to scritch, massage and comb my hair while rinsing, so these aren't completely identical. But the realisation still made me smile.
It's great for rinsing out the bulk of conditioner without getting wet all over, which can make me cold before I've gotten anywhere with the rinsing.
This is continued from the Ardha Uttanasana-pose above: I shift back and forth some to get to rinse the scalp and length.
This is especially good for cassia-treatments where you want the bulk of grains out of your hair with as little rubbing and scrubbing as possible.
Hair is fragile and stretchy while wet, so making a habit out of limiting handling is a good thing!
You should always focus on cleaning your scalp, but not comb your wet hair unless it's necessary for tangles or shifting it from one pose to the other.
This is my final pose in the cleaning process: I like to sit back, relax and give my scalp the last bit of attention. Leftover product on my scalp can make me break out. I comb, scritch and massage the scalp. Then I let the water gently rinse my hair backwards to prepare to braid it or put it up after.
