From a customer question:
Plz clarify there difference between rh1488 and rh1488 M. I would like the brighter and blonde of the two, thank you for your help.
Hi all. Heather here. :)
I figured I'd answer this one personally since I know these colors ridiculously well!
They are the exact same color. Seriously, they're exactly the same. The only difference is on the inside of the cap and is not visible to anyone looking at the actual hair.
The difference is that the "M" colors have a lighter cap interior. I made a video about these things earlier in 2018: https://youtu.be/GlCVTk0baU0
