No difference.
I used this 3 times. I followed the instructions and saw no different in the damaged areas of my hair. I’m glad I purchased the trial size which is still expensive so it’s going back.

I’ve used it 3 times so far and I can feel the difference in my hair. I recommend doing research on how best to use it as the instructions aren’t great. Abbey Yung has some great YouTube videos
