I to had a HT with Dr Jones 8 weeks ago before the HT I had my Stylist use a #3 blade on his hair trimmer.The #3 blade was short enough for Dr Jones, he did not have to cut my hair. Also for the back of the head you could not see the stitches on the strip.I went back to Dr Jones 10 days after the HT to remove the stiches the lengh of my hair was long enough not to see the scar from the HT. After 8 weeks the scar is still red but not as noticeable as each week passes my head is starting to feel like it was prior to the HT.Good luck
