After my previous review, Karen messaged me and explained that the green colour is from the toner and should wash away after 4-5 washes, and it really did!
She offered to help tone it again, and did a great job following up and messaging me every now and then to check up on my hair. You can tell she really cares about her clients.
I never took up her offer however, because the greenish colour washed away and now I'm quite satisfied with my colour.
The cut was still lopsided however, but my cosmetology teacher (who used to be a hairstylist herself) noticed and helped me even it out, so it's now not longer on one side anymore.
Karen also explained some more details form my previous review.
The customer service is great. My hair turned out to be fine too.
I'd rate this 3.9
At the beginning my experience was kind of sour, but they actually replied to my complaints and offered to fix it. That really blew me away.
