In the last pic now , that shows an exposed front hair-line so it will be necessary to get Swiss lace for the front...the style and hair length would be a bit of a stark leap from your present condition ..even though you use concealers, the hair is quite short..... I`d `transition` gradually if I were you .... your present sides are too thin to get away with that fuller look as in the last pic there. .... you can easily see that guy has good thick/er hair at his temples ..your temples are much thinner...... if you`re going to go for a higher density at the start, you`ll definitely need to leave the sides come `out`[grow] more or it will not be possible to get an `invisible`blend ...... I posted pics on the other thread where the new chap was looking for advice--it shows a 55% density on me ....might give you an idea of how it might fit in with your plans.
