It is important to space out brow laminations with enough time between treatments - the brows will also go through a grow out phase and need to be styled with brow gel at around the 2-3 week mark.
Please keep in mind it’s normal to have some brow shedding when you are brushing your brows, it’s normal for brow hairs to grow and fall out, however when we are brushing the brows more frequently, we’re going to notice this more than when we’re not brushing the brows. This is not due to the lamination - just our natural hair growth cycles.
