I am naturally a medium-auburn (the dreaded natural reds) and I keep my hair a nearly-silver platinum White for about 9 months now. Doing platinum at home is typically something I'm too lazy to do, but hitting my mid-30's I said to myself: "Nothing other than a boring color really makes you look better/younger after 30....so I should do whatever color is actually fun and not worry about how flattering or age-appropriate it is". And that's how I went from natural brunette with a few highlights to DIY Platinum in *literally* one day. (Yes I had chemical burns because I had to bleach 2x and did so in one day and then toned 2x in the same day, as well). I don't recommend you do ANY of that unless you are SUPER familiar with your hair type and know how it's going to react to double-processing, certain brands, etc. I have been coloring my hair since age 11, so I feel confident that no matter what I do *wrong* I can fix it. So please keep that in mind in reading anything I post about "blonding" yourself.Second....the snooty comments from "Professional Cosmetologists" and such are helpful and contain factual advice....but pretending that a Cosmetologist can do a better job that *yourself* at home if you are educated in haircare is blatantly dishonest. I have been colored at the very best salons that charge up to $500.00 for my hair....and frankly, anything other than a $300.00 quality coloring, I can do better myself at home. Including Platinum Blonde, bleaching, toning, and the dreaded root touch ups for a platinum blonde with dark/black roots coming in. I did my full platinum myself and then the first root touch up using Schwarzkopf BlondME Bleach (awesome) with Wella 20 Developer and then double-tone. First I use Wella T10 mixed with T14 and a touch of T050 (which is listed as a "dye" but is a purple additive specifically to add to blonde toners). Then I rinse and apply the T18 (or White Lady) to the roots first.....then the shaft and tips for a much shorter time.This gives me a solid White Silver Platinum with NO gold or hot roots and none of the "gold banding" I experienced at my Redken Salon AND at my local Aveda Salon. Both places charged me over $200 (not including tip) JUST to touch up my roots after I'd already done the Platinum myself. BOTH screwed it up and left me with yellow roots that were patchy and clearly showed their inability to listen to the customer when I told them that I have "very resistant roots/hair even when it's virginal hair that's never been colored". The best colorists out there are the colorists who listen carefully to their clients about things that only the client can know about their hair and absolutely change the results. Anyway....after being lazy and going to 2 "fabulous and expensive" salons and getting crappy results, I went back to doing it myself using just Wella Toners (though I still prefer the Schwarzkopf "BlondME" Bleach for up to 9 levels of Lift....I just use it with my Wella Developer).The T18 IS going to give you a "grey or granny" color at first. That's a GOOD thing. I know it's not the gleaming platinum you wanted to show off to the world, but if you rinse and have this greyish tone....you've gotten the most important thing done: abolishing the dreaded "yellow" hints, tones, or roots. The shaft and tips of hair will fade quickly to whatever color you were going for (likely platinum white to very pale blonde) and the roots will usually stay a bit darker....but not orange or yellow. BUT. If your hair was NOT totally "pastel yellow" prior to using the T18, you will NOT end up with a platinum/pale blonde overall. You'll get light blonde with yellow hints because the rule is that: Violet-Blue & Violet (T18) covers light yellow and gold (and will appear purple or silver at first on your lightest strandsBlue-Violet & Blue (T14, T10) cover light orange, gold, and cast a silver tone on pastel yellow and whiter pieces of hairNeutral Tones will basically tone the brightness of a bleached blonde to a "peachy" color at first and hopefully settle down to a regular "golden blonde", but is NOT good for neutralizing orange, gold, yellow that is unnatural looking.When I use T18 I have a routine that is NOT pleasant or easy and requires confidence....but gives me much better results than the Colorists at Aveda or Wella Salons can give me. I bleach my roots and any faded areas with NOTHING OVER a 20 Developer. In my opinion, it is better to have to bleach it twice with a 20 Developer than risk using a 30 or 40 Developer at home. The "speed" of using the 30 or 40 is NOT worth the risk and damage to your hair. I also add "Bond Angel" to both my bleaches and toners. Bond Angel is like Olaplex. It's a reconstructive/protective ingredient that salons charge a TON of money to add to your coloring and are also expensive to buy online....but the Bond Angel is lesser known and you can buy it on Amazon to add extra protection to your bleaching process. After bleaching either once o...
