I decided to go ahead and try a heavy oiling since things have been working out for me with MM and I wanted to try more stuff I left Euro oil in for 24 hours then washed it out with Earth Essence. I kept the first wash in my hair while cleaning my body and when I rinsed it out I FELT like the oil was already cleaned off, so for my second wash I didn't bother getting the ends and just did another normal scalp wash. That was a mistake hahaha! When my hair dried, my scalp WAS clean and looked just fine! But the ends were oily still. So the next day (I NEVER do daily hair wash normally) I got a large bowl of water and mixed about the amount I'd use for 2 shampoos w/Pine Shale into it and dunked my hair in and washed out the ends. I think I did a tiny second shampoo after as well, but after all of this, my hair was perfectly cleaned. (Note: I normally tend towards being overly oily with dry ends, but this is related to some other factors like touching my hair/scalp too much, long story, but I wanted to point out it's NOT always been easy for me to get excess oil out, so to me this means that MM CAN accomplish it, I'd combine those techniques if I try again)
I have read of people using other oils to push their own sebum down the strands too, but that never seemed to be the case for me. Thought I should mention it in case anyone here thinks it might work for them.
As for how I feel about my heavy oiling - I don't really have much comment on it. I loved that I was able to detangle my hair so instantly while it was oiled and before getting it out completely (I have -super- tangly hair), that made me ponder just how much I need to work on my hair's condition still. I can't tell if I would benefit from oiling more often, but 3 or 4 days after that Pine Shale wash I decided to do a conditioner-only with Pearl Essence because I didn't think my hair really needed a wash yet (but felt inclined to do something, I think I'm addicted to the idea of nourishing my hair/scalp now), and that upkept my hair for another 3-4 days.
