Q:

hi

I come from china ，I would like to consult your organization a few questions:

In your experience,usually Asians（chinese people) the normal growth of the number of roots Per cm² of hair? Head at the top and post-occipital whether there are different?
using FUE technology，on one operation ，After the occipital Site  get the maxinum number of FU (Asians including 2-3 days operation) at present,how much FU can be planted per square centimeter on Planting area? Between the scope of? and the percentage with normal?

Looking forward to your reply Details!

Thanks for your questions.

A:

Here are the answers in the order they were received:

The number of hair follicles

The number of hair follicles in non-balding areas of scalp like occipital areas have been studied.  A range of 80 – 120 follicular units (FUs) per centimeter were reported. The density of follicular units vary in different locations of the scalp. Also, the number of hairs per follicular unit vary in different areas and with different races. For example, Asians usually have less number of hair follicles per cm², so even with similar number of FUs per cm², the density of their donor area is still less than Caucasians. To calculate the number of hair per cm², you have to average the number of hairs per FU and multiply it by the number of FUs per cm².

Difference of hair on top and back

The shaft of hair may or may not be different in different areas of the scalp. Obviously, if you are balding, you see more miniaturization and less terminal hair, which makes the appearance of the hair less dense on the area. However, without baldness, hair quality would be the same in back and top of the head.

FUE and number of grafts

FUE (Follicular Unit Extraction) is more labor intense and requires more time for harvesting the grafts. For that reason, FUE procedures are generally smaller in terms of the number of grafts per session. What we do at US Hair Restoration is up to 1,500 grafts per day on average, for 8 to 10 hours work in a FUE procedure. The number may occasionally go up to 2,000 grafts, too, but not everyone can expect to get that number with FUE.

Density of transplanted hair

There are many research projects on this topic. The number can be as high as normal density in some circumstances. However, practically we can make up to 35%-40% of the normal density in one session. This is a good number if you consider that the density of hair on frontal areas could be about half of the hair on the donor area in some patients, so 35%-40% is not that far from the normal density in those patients.

The effectiveness of medical hair restoration alone with hair restoration medical options that are currently available such as finasteride or Rogaine has always been questioned.  Medical hair restoration without the surgical option (hair transplant), might work for some people, but should not be recommended to all as a cure-all solution, as you may find in some advertisements.

The available FDA-approved medications for hair loss prevention are finasteride and minoxidil.  Although both are effective, they may have different indications for male and female patterned baldness. They might not be considered a complete treatment for male patterned baldness, as pharmaceuticals may try to show.

Medical hair restoration should be seen as a preventative measure which should be considered, along with the surgical options, as part of a master plan. Most people are prone to shock loss that may happen after a hair transplant surgery and they need to be on preventative measures such as finasteride at least a few months around the time of surgery. Shock loss after a hair transplant used to be one of the biggest problems that hair transplant patients had up until the last few years. Now, most hair transplant patients go on finasteride after a hair transplant surgery.
