Balayage vs Ombre
If you would like to get another balayage/ombre treatment, how much time must pass after the first treatment? Well, in general, you must wait 2-4 months. This period will be shorter for graying women though.
And the great news is that both treatments are not really damaging as both are done without any ammonia. The traditional treatment with foil is more damaging, comparing to balayage. However, if your tresses are very dark and you wish to get light ends, that might take more treatments. But even in this case, if your hair stylist is an experienced professional, your tresses will remain healthy.
