Scalp Reduction And Donor Stretching Simulation

(0 votes)

If you observe the video below, you may see that density on the simulated scalp reduces as it is stretched. The more the scalp is stretched, the more the hair density is reduced. This rule can be applied to strip hair transplant (FUT) harvesting method because density is calculated based on quantity of follicular units over total area under consideration. After a reduction, the crown hair growth direction tends to move lateral away from its natural forward growth angle. There is also a change in hair growth angles in the donor area following a strip harvest. Some "stretch-back" may help increase density on the scalp to a small degree. Tissue elasticity varies from patient to patient but reducing the scalp area inevitably reduces density. The total number of follicular units never increases after any reduction or harvesting and the overall appearance of the scalp and hair growth angles will be altered.

For physicians, the only benefit of reducing the scalp is that the length of the surgical procedure is considerably reduced. For the patient, the benefit is the reduction in expense for the procedure. The actual gain by the scalp reduction is usually partially or always lost after "stretch-back" occurs. This means the net gain is minimal

Density = the number of follicular units / surface area. Therefore, density decreases as surface area increases as a result of stretching forces.

I am so glad I found this post. My husband is starting to bald and he feels so self conscious about it. I really think that hair simulation could work for him. Wish us luck!
