Asian Hair

Sunday, January 10th, 2010

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.

Scalp Hair Miniaturization

Wednesday, February 27th, 2008

 

Miniaturization of scalp hair is a part of the hair loss process in which hair becomes finer over time before falling out. Microscopic evaluation of the scalp and hair can help determine the rate of miniaturization on human hair. Balding in men and women usually is not obvious until significant miniaturization is present.

Patient observing his miniaturization test admininstered by dr. Parsa Mohebi, MDScalp miniaturization mapping is necessary for most hair loss patients to predict their future hair loss.

The appearance of baldness is not obvious until more than 70% of hair is miniaturized in most people. A miniaturization study should be part of the hair loss evaluation of a patient and could be used as predictor of future balding in a given area. Significant hair miniaturization is seen in patients who are in the active phase of hair loss and this evaluation could determine a patients’ response to a certain type of medical treatment.

mapping of scalp miniaturization

Microscopic evaluation of scalp hair shows significant miniaturization.

Here at US Hair Restoration, we map the patient’s scalp with miniaturization study as part of initial hair loss evaluation before starting any medical treatment or performing hair transplant surgery. Young patients with significant miniaturization are prone to losing their vulnerable hair after a hair transplant surgery due to the stress of surgery on skin and hair follicles. This phenomenon is called shock loss and occurs less in patients with minimal amounts of hair miniaturization.

Miniaturization of scalp hairDr. Mohebi evaluates all patients for donor density and miniaturization rate in balding and non-balding areas.

We consistently track our patients through miniaturization studies when they are on a treatment plan to gauge hair gain or loss. This way we can objectively evaluate the effectiveness of our treatment.If you are balding and are willing to do something about it either by hair transplant surgery or medical treatment, you should have your hair mapped for miniaturization to have a baseline assessment of current hair loss status. This way we can assess the effectiveness of medications and predict in which areas you will have the most hair loss. This can help your hair transplant surgeon cover areas or future hair loss so that you are not obliged to take on multiple surgeries to chase the balding hair.

Miniaturization study.


Having 10 to 20% miniaturized hair could be normal and not part of the balding process. Scalp hair goes through two main phases: Growth phage (Anagen) and resting phase (Telogen). The Growth phase in scalp hair of normal people can take between 1 to 6 years, where the resting phase is about 4 to 6 weeks. When we lose one hair to the telogen phase, another hair will grow from its follicle which will be represented by a few tiny hairs showing hair cycling, in the area and not necessarily the balding process.

If we see over 20 percent hair miniaturization in a general area, it is common indication of active hair loss in the area. Higher numbers of miniaturization could represent active hair loss and progress of balding in the future.If you are a balding man with significant miniaturization, you should take finasteride after mapping your scalp. The effect of medical treatment of baldness is very gradual and may take at least six months for any detectable improvement in miniaturization of hair.
