Swiss, if you blade shave, you should wait about 10 days. You can, however, shave with a foil shaver or clippers after day four. Avoid washing your scalp with soap for at least three days. If you're going to be in the sun you may have to wear a hat/cap/stocking cap to cover that area. A fitted cap might be better, as a cap with the adjustable strap may still leave the treated area exposed. If you don't mind me asking, is the punch scars all the way around your head or just the strip shown in the pictures? One more thing. If you've only had one treatment, I would wait about 7 days before you go for the second treatment and about four weeks for each treatment thereafter. But every case is different, what I posted is for the average SMP patient. Good luck!
