Why Is Mole Hair Different?

This isn’t about hair loss, but I’m the curious sort and I figured you might be familiar with this. I’m a blond guy in my 30s, good health, no hair loss that I can tell, but I have a mole on my shoulder that grows a single black hair. The mole has been there for as long as I can remember without growing larger and I don’t think I have anything to worry about as far as cancer. The mole hair seems to grow faster than the rest of my body hair and is an obvious different color and texture. Why is the hair different like that?

There is clearly some different genetics in play here and that is the best answer I can give to your question. If you don’t like your single dark hair, you can have it removed or burned with electrolysis. The mole can also be surgically excised for cosmetic purposes.

When I read the question I thought you were going to ask about moles — the mammal. I knew that moles have a high hair (fur) count. Here is what I found on the web:

Mole Hair – Sometimes considered pests, moles are often trapped or hunted for their fur, which is quite unique. Soft, velvety, and very fine, mole fur is especially adapted to facilitate the animal’s underground movement in any direction, smoothly lying down no matter which way it points. Thus, when mole pelts are made into coats and other fur products, the fur can be brushed in any way the designer or owner chooses. Quite valuable, demand for mole fur has caused significant population declines in some areas.

Also I found out that the Alaskan Fur Seal has a huge hair count of 350,000 hairs per square inch when compared with the human as 1250 hairs per square inch. That hair count keeps them dry (water can’t get through it) and warm (a great coat).

Oh come on, I can have fun — it’s April Fools Day!

Why is it not wise to get a hair transplant at 20 year old?

I keep seeing this pop up. I am 19 right now with a NW2.5-3 and just started taking finasteride. My plan is take fin for a year then — assuming I respond to finasteride normally (just maintain hair, am not a non-responder/super responder) — get a hair transplant at 20/21ish. Why would this be such a mistake? The finasteride should roughly maintain my hair for a decade or so, right? I’ll be able to live and experience a normal young man’s experience. Once it gets bad, I can just shave it once I’m older (which is not nearly as big of a deal), or I can get another procedure. Or hell, maybe there’ll finally be a cure for this shit disease by then lol. I just don’t get why it’s considered such a big mistake. I would honestly almost rather be bald than have these shitty temples, even if my density is still solid.

It is not wise to get a hair transplant at 20 years old because you can’t make a Personalized Master Plan as your future hair loss pattern doesn’t appear for most men until 25 years of age. Without a good plan, you start the transplant, use up the donor supply (which is limited) to deal with your short term problems and then when you keep losing hair you are out of luck as there is no more donor hair left. By then you might not just be bald, but freaky looking (nobody should look freaky). I have seen too many patient who did hair transplants at 19 or 20 and ended up regretting it.

Why Is Hair Transplantation Not More Common?

thanx for the informative blog. i have a question, despite of such enormity of hair loss problem , why the hair transplantation is not so common.

It takes time for people to accept a new breakthrough in surgery. If you look at female breast augmentation, it took more than a decade for women to feel comfortable enough with it to step up and undergo the surgery. Most people think that hair transplants can always be seen and when they run into a person with plugs coming our of the scalp, they get the idea that this is a hair transplant and say to themselves, “This will never be me!” Today’s hair transplant can not be detected, so the good work done regularly is not something that the average person can detect unless you can remember what someone looked like before they got the hair transplant. A woman with an “A” breast size can be detected when she gets breast augmentation and one day comes out with a “C” or “D” size showing good cleavage. Only a bald man who now has hair, can be detected much like the woman with the newly larger breasts.

Why is Hair on the Back and Sides of the Head More Resilient Than the Top?

Just wondering what is responsible for the pattern of “male patterned baldness” ?

Why does the hair at the back and sides of the head seem to be more resilient than the hair at the top ?

Thanks Doc.

It is called genetic male pattern baldness. Keyword is “genetic”. Genes are responsible for it, but as to the reason it works out that way, I haven’t a clue. I posted a theory about it before — Why Does the Back and Sides of the Head Not Lose Hair?

Why Is Hair Loss Not Listed as an Official Accutane Side Effect?

You said on one response that if accutane had caused the person’s hair loss then drugs would not help to fix it, could you please explain why this is? And why does hair loss not appear on
the side-effects section of the medications packaging?

I do not have the drug insert on accutane, so I don’t know what is listed on the packaging. Many dermatologists tell me that there is no effective treatment for accutane-induced hair loss. I would write to the drug manufacturer or ask your pharmacist about the warnings in the insert.

Why is hair loss irregular with age?

I just don’t understand why the earlier someone starts balding doesn’t always mean they bald extremely quickly. Like what explains a 30 year old balding almost completely in 2 years vs a 20 year old who starts balding at 20 but takes 15 years to show significant loss?

Again, it is tied to the genetics. Each hair in a region has a finite number of hair cycles to it. when the hairs go through its limited # of anagen growth cycles (a growth cycle in men is between 2-3 years), then the hair often dies. The death may be partial in the Folliclular groups (normally say a hair follicle has 3 hairs in a group, one of two my die off) making the hair look like its is thinning from above (it is thinning) and eventually that last hair will fall out sooner than later. So for an aggressive balding pattern (Norwood Class 7 pattern) the number of three year hair cycles for all of the hair from the front to the crown might be 8 cycles (pre-programmed at birth) of 3 years (3 times 8 = 24 years old to balding). Not a good scenario. Most Class 7 men will be bald by the time they are 26 years old. The same thing can occur in older men 30, 40 or even 50 and they may lose parts of each Follicular group of between 2-3 hairs each) and then eventually the rest falls out at its pre-programmed death. Drugs like finasteride, prolong these cycles making the hair last longer.

I hope I didn’t confuse you, but I got stimulated to give you a scientific view of the process that you are describing in different men of different ages.

Why is finasteride a must after a hair transplant?

If you have miniaturization on your scalp in the areas you are balding and then have a hair transplant, the miniaturized hairs get shocked out and often fall from the head. So we call this Shock Loss following a hair transplant. Finasteride can prevent this from happening.

Why Don’t You Reveal Who These Bad Doctors Are?

The following is a comment I received on the post from last week, How Many FUE Grafts Actually Grew?

Please let us know who this Dr. is. I know you do not want a reputation of badmouthing Drs. — but for the benfit of those of us who do not want this type of result, please mention it — it is not badmouthing, it is warning. At least the State where this Dr. practices. What good is a warning, if it isn’t linked to a culprit?

We maintain a policy to not slam specific doctors. I don’t want to open myself up to any legal action and honestly, I’d prefer to focus on revealing the scams some doctors pull and encouraging users to do their own research on any doctors they are considering.

We hold open house events each month where any patient can come in and say whatever he/she pleases in front of a very interested audience. I would challenge other doctors to have this same policy, which would obviate the problems that this patient had.
