JRob is right--that style is SO easy to achieve with any hair system. I assume your brother is relatively young? If so, he`ll be able to `carry off` a slightly higher-ish density --in the event that it needs to be thinned out a bit, that`s easy enough to do by dabbing on `dots`of hair-removal cream but, as JRob was saying--this is not an exact science.... it [density] can vary depending on the individual ventilator..... I had to do a lot of thinning on the first full-cap ..it was definitely quite a lot higher than I required.....but to be honest, even though it`s a bit tedious, I`d rather be having to thin it than looking at a system which was lacking hair when it arrived i.e. too thin/light ....in that case all a person can do is send it back to have more hair added which will further delay being able to wear it.....I`ll be posting some pics on a new thread this evening showing the new [non cut-in yet] fullcap which arrived this week.
