Hi Fran,
Suzie is growing a top knot and you can deal with it in a number of ways.
You can either hand strip it out. This will give the smoothest finish but does take time. Lift a small tuft and with first finger and thumb gently pluck the hair out. If it is ready to give it will come out fairly easily. Between plucking, brush the head and then you can see if you have done enough or if there is there more left to come out. Its very easy to keep going at one area and end up with a bald spot, so be careful.
Second way is with thinning scissors. Lift the tufts and go in from the back with the blades pointing towards her nose. Only a couple of snips at a time or again you'll get a bald patch. Brush it through and see if it looks smooth enough. If not repeat until it is.
This gives a fairly similar result to hand stripping but it won't last as long or grow back as smoothly.
Third way is to use clippers. It is by far the quickest but it won't give the softer, smooth finish that the other two ways will.
