Would it be okay if I dyed my hair Schwarzkopf's light cool blonde after using Olia's B+++ yesterday?

I'm not a expert with hair dying as I just start to dye my hair since a half year ago. I am familiar with bleach though.

Bleaching has three stages where it change to orange and finally to white. If yours turned out yellow-orange, it means you had it for a short time OR bleached it on dark hair ( which would be better if you had bleached in steps such as sections or highlights).

Now, for Schwarzkopf hair dye, it has some bleach in it (lightening a few shades = bleaching), but much milder than the stronger ones. IF it was a regular hair dye that doesn't lightening but only cover the yellow-ness, i would rather recommend that ---or wait a few weeks using hair masqs during the time let it recover. In my experience and what I learned from hair dressers, It's better to wait to re-dye/bleach your hair a couple of weeks than doing it repeatedly as I personally find that method does no good - both for your hair and the results. You "can", but the color results doesn't always end up better.

Personally, I would recommend Color Refreshers in Silver-Grey-ish shades to neutralize the yellow-orange tone. These are conditioners with pigments, a much milder and nicer to your hair than toners.. I use a Swedish brand called Maria Nila (a small jar 100ml that lasted me for 3+ usages depending on length/thickness), but there are surely tons of others where you live.Non bleaching Toners ALSO cause some damage, but when dying, they are better if you need to redye your frequently. There is also silver/violet shampoos but they don't always work on hair that was discolored from a bleach/dye and easily turn to purple if you don't watch out and very drying to the hair.

Here is an result example, except I used a gray/black refresher which made it a bit darker: https://c1.staticflickr.com/5/4494/37616705811_345...

But like I think most who works with hair dressing or cosmology (I'm more experienced in makeup than hair), Whether you think its healthy or not, its up to YOU to decide that whether you want to take the risk. Just make sure to use conditioners and hair masq regular whatever you choose to do, so no, its not stupid, it just very risky coz Schwarzkopf is still a bleach and can be a bit unnecessary unless A) You want to get more lighter, ie white blonde or B) just cover up the yellow ness from the bleach. If its for B), I wouldn't recommend it as I mentioned earlier.

If its a money concern and only have that dye, use it on your own risk. :Some hair can endure bleaching and dying better than others (In my own experience, dying it over doesn't always cover up the yellow-ness unless you bleach it white level which is very risky if you dont know what you are doing).

I've always had a hard time finding high quality sulfate free and sodium chloride free hair care products. I am so glad that I discovered Arganlife Shampoo

I would strongly recommend waiting two weeks before lightening your hair again and in that period using conditioning treatments on your hair and actually trying a toner instead of frying your hair. If you have an orangish-goldish, yellow, or brassy tones, it is quite an easy and wayyy less damaging fix. Wella has amazing toners. If you do decide to lift your hair again just be careful with the levels, once you're past a level 10 your hair is done for. Just be safe, do some research!! (:

Sure
