First, sorry about the first couple bailing; hopefully another buyer is still very interested.
Second, in terms of baking soda, I wasn't using it to strip a lot of oil. I made a loose paste (about the consistency of shampoo) and put it on my hair like you use aquaswim. I also have cradle-cap, and it was good for sorting that. now that it's sorted (or seems to be), I opted to switch to vinegar which also strips the hair and preps it for the honey treatment.
Honey -- when in water, or for that matter on human skin -- naturally chemically reacts to create peroxide. If you put honey directly on a cut, not only does it have all kinds of natural, anti-microbial goodness, it also creates peroxide and it's *that* which really cleans the wound. We use it instead of triple antibiotic ointment. Usually, it solves/prevents all problems. When problems arise, we will move to the "heavy" stuff if need be. I haven't used the other stuff in over 3 years though.
So, likewise, honey can work to lighten your hair. 1/4 cup of honey to 3/4 cup water in a glass container. I then add 2 tbsp coconut oil, which also has a peroxide-ing element. I let it stand for 45 minutes -- that's about when there's the right amount of peroxide to lighten hair.
The next step is to run this rinse through your hair over and over and over. I start with a basting brush to get all the roots, and then I pour it out of the mixing cup, through my hair, and into a bowl, and then bowl to mixing cup, and then over my head into the bowl, and so on. I do this until basically there's no liquid left.
After this, I wrap my hair in one of those microfiber towels which I got wet. The hair needs to stay wet to process. I then put a dry towel over my shoulders. Let it sit for an hour. IF the outter towel starts to dry, I use a spray bottle to keep it damp.
Once that's done, I rinse with clean water, and it's done.
You get a nice, subtle lightening (not to be used on treated hair. it will lighten natural, untreated hair and also henna'd hair). It's great for blondes who muddy (like me) at the roots. And, it only needs to be done once a month, really.
The honey and coconut oil provide all kinds of nice conditioning properties to the hair in the process, which of course regular peroxide doesn't. It's pretty cool.
