Can you use this before pre wash?

In the photos it says you can use it as a pre-wash and right after your shower. If you’re asking if you can basically add it a second time, after you’ve washed and its been a day or so? I imagine thats ok depending on your hair. If it was ok with the first application and you feel you need more, I would think that would be ok. It’s just important you don’t over-do it. ☺️ Hope that helps!
