Commercial hair dye was my last chemical holdout. I'd been dyeing my hair since I was a kid practically, thanks to the premature grey gene.
I'm letting my hair grow out (yet again). I was also using a medium to light brown dye. I read that you could crush up VIT C pills, add dish soap to make a paste and smear that on to lighten hair. It did work, but I had rosy pink patches here and there at the roots (!) and my hair was like straw.
So now I wet and towel dry my hair, work in some baking soda to the colored part, wrap with a plastic bag and sit around reading here for a while. It's lightening up the dyed part, and now I have no dye in some places, just my natural grey/white. Actually looks pretty decent considering..streaks of blond shades coming thru.
Anytime you lighten, you go thru 7 shades of red, my first was the most shocking copper. Got better after that, though. It sure is making the growing out transition easier as there's not such a definitive line there.
The thing that works for me is 1TBSP or less of Borax disolved in one cup of hot water, then cool. I wash with that and then use vinegar water for conditioner. I couldn't believe how much better my hair felt after the first time. No heavy conditioner residue to weigh my wavy/sorta curly hair down. Very shiny with the vinegar rinse and dries fast. I'll never go back to commercial shampoo/conditioners. My hair felt 100% better after the Vit C episode, too. Oh, I read that your hair doesn't care if it's white vinegar or ACV. I used both and got the same results.
For homemade gels, I'm clueless. I do remember people using sugar water a looooong time ago.
Oh, BTW, stress can bring on episodes of dandruff. The only times I ever had it is when I got married (oh joy) and a few times when my mother came to visit.
