I noticed in the post by bubbles linked bellow that he said it is necessary to use stick and place when making recipients with small needles. Jessica and Fit2btied pretty much rubished this idea.
The link bellow is an article by Dr. Limmer
In his review he clearly agrees with bubbles so I thought it fair to show this in his defence.
During the implantation stage, the follicular unit grafts are placed into the anesthetized recipient zone using small punch holes (0.75-1 mm), small slit incisions (1-2 mm in length), or needle tunnels made by 19- to 22-gauge needles. If using the punch or slit methods, the recipient sites may be made prior to beginning the implantation process.
The needle tunnel technique, also referred to as the stick-and-place method, requires that each graft be placed immediately after the needle has been removed, since the needle tunnel remains open only for a few seconds. An 18-gauge needle is preferred for implanting 3-4 hair grafts, while 19- to 20-gauge needles are used for implanting 1-2 hair grafts. The stick-and-place method provides greater density of follicular units within the recipient zone and causes the least trauma to the vascular system in that area. Thus, this is the method of choice for some physicians. Because of the smaller size of these grafts, it is important to handle them with extreme care and to keep them hydrated at all times. A goal of 20-40 follicular unit grafts per cm² is reasonable and readily achieved by skilled assistants.
