Highly recommend, 10 out of 10. Didn't know what to do when this follicle test came up. I’m Heavy every day smoker, Dabs, and I found this method online looking at the original Macujo method ...
Moreand this shampoo was a must have. I ordered it and it came overnight, life saver, and used the method on this site 3 times a day for 4 days. I also bleached it once before I started all of this while waiting for the package to arrive. Side note: they cut my hair from my cowlick at the crown of my head so make sure you cover everything!! I passed and I am so relieved and grateful that I spent the money and followed this to a T even thought it was uncomfortable. Good luck!
