Well it's been over 2 weeks and my hair is completely back to it was - and yeah it's super thick so I'm going to give it another go! Wish me luck!!!
Also about the bad haircut, I must say, shockingly I've gotten really good feedback and it turned out to be way more flattering!
Now another question - if I do a strand test (to make sure it doesn't fall out!) do you think I can re-use the stuff even if i opened the tube?
Also any advice regarding course roots?
