HAIR GRAFT DENSITY

One major complaint in hair transplantation, it is the lack of density we are able to achieve over the bald areas. To understand the density issue, you need to realize that at birth they had approximately 100,000 follicles covering the scalp. There were 40,000 follicles over the donor region (sides and back of the head) and 60,000 follicles over the frontal region, midscalp, and crown. By the time you recognize that you are losing your hair, you have lost half of the original hair. Fortunately, we don’t need 100% of the birth hair to achieve a cosmetically acceptable result, but obviously the more extensive the loss the less surface coverage and density we are able to attain. There are many factors to achieve a good density in hair trasnplant.

– Hair density and hair shaft diameter play are very important in determining the cosmetic density we achieve. The thicker the hair shaft, the more visual impact we will see after transplantation.

– Scalp elasticity is another important factor in achieving density. The more elastic or loose a person’s scalp, the wider and the more numerous graft strips can be removed either in one, two or three surgeries.

– The smaller the recipient sites, the closer we can place the next graft. This will reduce the space or gaps between grafts to give the appearance of density and fullness.

Depending on the patient’s available donor density, it is possible to transplant 4000+ (10,000 hairs) follicular units in one session. Dense packing is often the reason patients rave about their hair surgeon.

The artistic skill of the surgeon and the way the grafts are distributed as well as the direction and angle of the hair shafts. Each one of these items is significant to a fuller head of hair.
