Is My Donor Hair Thick Enough for Hair Transplantation?

Tuesday, November 22nd, 2011

Q:

Miniaturization Study Performed on A Balding MaleIs my donor area thick enough and did I have any signs of miniaturization there? Most men I have seen that are bald on top have a much thicker back area of their hair that is not affected by mpb than I do. From your experience and knowledge is it good enough not only to be used as a donor now, but also in the future if I need to cover crown or do any other procedure. It seems to me that my hair is too thin in the back to conceal a scar and that it might possibly thin out a lot when im older. But I’m not a professional so please give me your opinion and insight. The scars all look thin enough for contentment but its when you dont have hair growing around it making it look like someone scrapped a bald line in the back of your head with a hair cutting tool.

A:

When I reviewed your microscopic exam I found it to shows you have only 10% miniaturization in that particular area.  Less than 20% hair miniaturization measurement is within normal range for someone with male pattern baldness (MPB). As we discussed before, if you keep your hair the same length as during your consultation, you should not be able to see the scar. We perform double edged trichophytic closure for most patients which minimizes the visibility of a scar even when you decide to keep your hair very short.

Stopping Finasteride After Hair Transplant

Monday, October 24th, 2011

Doctor Mohebi,

Q:

I wish to discontinue using both finasteride and minoxidil in the long run after minimizing the chance of shock loss following my hair transplant surgery.  Is this something we can achieve at my current stage or will I need allow further progression then have a second procedure?

A:

Patient observing his miniaturization test admininstered by Parsa Mohebi, MDStopping finasteride and minoxidil after the first six month following your hair transplantation will be alright.  However, you need to understand the risks involved, including continued loss on your existing hair.  Whether or not you need a second procedure is something that could be determined by a microscopic evaluation of scalp (miniaturization study).  If you have more than a certain number of miniaturized hair at any area, you will be running the risk of losing hair on those areas.

Stopping finasteride does not affect your transplanted hair, but you are going to run the risk of losing your existing native hair at any time you stop taking the  medications.

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.

Thinning Hair with Reddish Scalp Tone

Wednesday, May 7th, 2008

Q:

hi, why do men with thinning hair seem to have a reddish color to their scalp and men with thick a thick head of hair seem to have a whiteish color to their scalps……i find it a condition that exists in alot of cases several of the men i observed wear caps when they are outside so i’m quite sure the sun had nothing to do with it. one of my sons has a very thick head of hair……..”whiteish” scalp..my other son has thin hair and a reddish skin colored scalp.

again thanks for your help

A:

Thin (Miniaturized) hair is generally seen lighter and in people with dark but thinning hair, hair could be seen as light brown or reddish color, not because it has less concentration of the pigment (melanin), but due to its smaller size and less number of pigments overall. One of the first signs of hair loss could be lightening hair color in the thinning areas. Scalp tone is also a reflection of hair color especially in people with fair skin that you can see through the skin and hair shaft may alter skin tone.

Vitamins and Hair Loss

Sunday, May 4th, 2008

Q:

Hi Doctor,vitamins

My mother is obsessed with my hair loss and gives me a whole bunch of vitamins and mineral tablets everyday to help regrow my hair.
Do you think they work? Or should I stop them.

A:

Although lack of certain vitamins and minerals could cause hair loss in their sever form, living in north America and having a normal and balanced diet; it is unlikely that you are suffering from vitamin or mineral deficiency. On the contrary, if you look at your family pattern of hair loss, you probably can find other male members of the family who has similar male pattern hair loss. As I always say, you need to have the triangle of baldness, which is “Gene, Male gender, and time” to become bald. Vitamins deficiency is not to blame as part of triangle of male patterned hair loss. You can continue taking vitamins to please your mom, but don’t overdo it since vitamins are not going to bring your hair back. Instead you need to see a good hair specialist or dermatologist and undergo a good hair loss evaluation with miniaturization study and start taking one of the effective medications to prevent further hair loss or to use hair transplant to restore your lost hair.
