Comparing labels, the ingredients of box colors and professional colors are very similar. I think the only ones that have metallic salts are compound hennas and progressive dyes, which aren't commonly used. The issue is that for some reason box dyes tend to be tougher to bleach out. Idk if it's due to lower quality pigments being used or the amount of times it's overlapped creating more layers of dye the bleach has to eat through.
@@TheIntentionalClassroom Me too! Love your passion. I think we will come to the same conclusion though. K18 is the latest step in biomimetics and hair science but from what I gather is you do have to continue the usage at home to benefit. So it isn't a glue type technology like olaplex that washes away over time but it must wash out over time or disintegrate else it would not be needed again after the salon experience. I absolutely do agree with you that once the hair fibre is damaged to a certain point there is no turning back. I'm mad about science too.....thanks for your reply x
I really like your videos and your logic: science and experience approach. I have been using box dye at home for decades. I have often called companies to ask about the level of peroxide in their boxes. Most often it is 20 volumes for levels 1 to 8. And sometimes it is 30 volumes for levels 9 and 10, and perhaps even 40 volumes but only for those that are called "extra light". When we look at the pictures on boxes it shows results on hair two levels above and two levels below the level of the box dye, and writes " not recommended for other hair color levels". So, on average box dye use 20 volumes peroxides. Olia (Garnier) is now an exception. I think there is a mistake on their boxes: they have recently changed their box's pictures and it now looks like they are using an impossible amount of peroxide (ex: 9.11 have a picture that shows a grey result on black hair (impossible!) (www.garnier.ca/fr-ca/a-propos-de-nos-marques/coloration-cheveux/olia/garnier-olia-9-11-argent). I did call Garnier concerning Olia, about 2 years ago, and they were using 20 volume on all Olia (1 to 9) back then and the pictures on boxes were ok then. They may have changed the formula since or they make a printing mistake on the packages... As for the application method; if people read the instructions it clearly said (on all brands I used), for already colored hair, to only apply on the roots for 20 minutes and then 10 minutes on the rest of the hair (+/- according to brands). So the inconsistencies hair colorist experience with box-dyed hair comes from the fact that applying on one's own roots only, behind the back of the head, is kind of impossible.

Have you researched the science on k18 ? It's based on biomimetics and works on the Y axis and the X axis. Olaplex only kind of glues the X axis.
I haven't, but I totally will now! Thanks for the direction. I am always looking for new things to look into and research.
