Does touch-up affect timing?

Let’s say I go in today for a treatment, and I am scheduled for my 2nd treatment 8 weeks from today. If I go in for a touchup in 3 or 4 weeks, would my 2nd treatment also be pushed back by 3-4 weeks? Or would I still go in 8 weeks from today?

i wouldn’t try to time your treatments ahead of time. i would wait until you have enough hair showing after the touch-up to justify a treatment and make an appt at that time.
