As Seen on


Ever walk into a room with some purpose in mind, only to completely forget what that purpose was?

Turns out, doors themselves are to blame for these strange memory lapses.

Psychologists at the University of Notre Dame have discovered that passing through a doorway triggers what’s known as an Event Boundary in the mind, separating one set of thoughts and memories from the next. Your brain files away the thoughts you had in the previous room and prepares a blank slate for the new locale.

Thank goodness for studies like this. It’s not our age, it’s that damn door!


Reuters (8/19, Seaman) reports that research published in JAMA Internal Medicine suggests that too many individuals are being screened for cancer near the end of their lives, not when they are young when early cancer screening can pick-up deadly cancers when they are curable.

Bloomberg News (8/19, Ostrow) reports that researchers found that “more than half of men 65 and older who had a very high risk of dying in nine years were screened for prostate cancer, a slow-moving disease.” Nearly “38 percent of older women with a similar life expectancy were screened for breast cancer and 31 percent were screened for cervical cancer despite some having undergone a hysterectomy.”

Vox (8/19) reports, “Among patients with the shortest life expectancies (about five years), 40 percent had been screened for colorectal cancer.”

As baldingblog’s readership is largely young, you should ask yourself ‘what you are doing to detect an early cancer?’ Young people don’t think cancer, because they think that their bodies are fortresses and as such, are immune to cancer. Nothing can be more tragic then cancers in young people. Women who get ovarian cancer or colon cancer when they are under 40, have a high risk of early death because the disease is often picked up too late. Men who get colon cancer under 40, often die early. Smokers develop lung cancer at all ages. Early detection can address this problem at the diseases earliest stage. What is the message here? Go see your doctor and get a good history taken and have a physical examination and make sure you are screened for cancer. Don’t wait until you are 70, because you might just not make 70 or even 50 if you are victimized by some of these difficult diseases.


We just got the most up-to-date laser hair removal system in our office (The Laser Vectus System) and I stepped up to the plate as one of the earliest patients with this very new technology. My target was my back hair, my neck hair and most significantly my ear hair. I am sure you can see from the subject of this post that my vanity does dictate my actions. As for pain, it was barely detectable for me. Even if it hurt, I knew that the benefit for my ear hair was worth whatever pain it would cause, and once it was done, it was a non-event for me.

From reading our previous posts on hair cycling addressing Anagen and Telogen hair cycles, back hair is like any body hair, which means than only about half of the hair is growing at any one time. The laser only kills hair in the Anagen phase of hair growth. With this knowledge, I expect that the next time I do it (about 8 weeks), there will be new hair on my back that came out of the Telogen phase and went into the Anagen phase. As the laser can only kill hairs in Anagen, at my second session, half of the hairs that remain will not show (as they are beneath the skin surface in some ‘stem cell’ form), so I will have to do it a third time about 8 weeks later to get those hairs that were not in Anagen. The more times I do it, the less Anagen hairs will appear until they will essentially be all gone. My neck hair will probably have a growth cycle similar to my back hair; however, possibly with longer Anagen hair cycles so I am hopeful that the ear hair will have an even higher Anagen to Telogen ratio that would therefore take less sessions.

Now I am so excited about it, I might just tackle some of my chest and arm hair next, but my wife likes my chest hair so the problem is more of a ‘couple problem’ then a medical one. I knew women who did their bikini pubic area and underarm hair. We men may not be as bold and fearless as some women. If you are like me and your are in Southern California, you might now want to take advantage of our Laser Hair Removal Technology and make an appointment with us for an evaluation (see: This technology is not for everyone, especially for men with very dark skin (African Americans) or white hair (not easily killed in Anagen as the laser kills the darker hair only). We will offer anyone coming from this site a 15% discount off of our regular prices for hair removal to qualified candidates.

1. Have DPA young patients (Early 20´s) more oportunities with finasteride in comparasion with a MBP who have a normal patron (NW 6).
2. Have you ever seen a early 20´s with DPA who have a good response to finasteride for a long time (10 years)?

I am a 21 years old and I have taken finasteride since I was 18 years.. My dermatologist prescribed it to me.

Here you have photos of mine when I start the treatment (2012) and now

You have my permission to publicly use it.

Diffuse Pattern Alopecia (DPA) is basically the same as Male Pattern Balding otherwise known as Androgenic Alopecia. DPA, as the term implies, shows up as diffuse hair loss that occur in a “pattern” such as you see in male pattern balding but the permanent zone on the back and side of your head not impacted.

Finasteride (Propecia) is used for the treatment of this condition (DPA, AGA, MPB – they are all the same).

There is another condition called Diffuse Unpatterned Alopecia (DUPA), which may be genetic, but does not respond to the drug finasteride (Propecia). DUPA is uncommon; however, it is critical to have your doctor make this diagnosis before being considered a candidate for hair transplant or medication. These DUPA male patients often get a failure of the transplant, even if on the drug finasteride.

I cannot make a diagnosis with your photo and this blog is not a place for making diagnosis. I also cannot predict what will happen in 10 years. I am not a fortune teller. I have seen men in their early 20’s start finasteride for male pattern balding and has kept most of their hair. I have also seen them lose their hair rapidly despite being on finasteride as their genetic predisposition overtook the drugs ability to slow things down. It doesn’t mean that the drug didn’t work.

Can I have a Scalp Micropigmentation (SMP) and later a hair transplant surgery? What if I want to grow out my hair as well? I don’t want to always keep my hair shaved.

Block Quote

You ask a great question! We have been combining SMP with hair transplant surgeries using FUE or Strip FUT. After all we are a medical practice that specialize in all aspect of hair restoration!

This patient came to us with a old hair transplant surgery scar. He had a strip FUT surgery which didn’t really give him a full head of hair and he just gave up with the idea of having a full head of hair. But he had the strip scar which he couldn’t hide when he decided to cut his hair short. So he went to local doctor for FUE to the strip scar. As we tell all our patients, FUE to the strip scar doesn’t really give perfect results when you are looking to shave your head. So he ended up with MORE SCAR, many ‘punctate scars’ from the FUE surgery. Needless to say he was angry and was very skeptical when he came to see us. We didn’t blame him. He didn’t trust any doctors at this point. Although Dr. Pak thought he would be a great candidate for the SMP procedure, he actually turned him down because the patient’s expectations seemed unrealistic with a bad attitude.

Eventually, the patient came back for another consultation and even saw other SMP patients in person at our monthly Open House Seminars (where prospective patients can meet with former patients and see an actual SMP or Hair Transplant surgery taking place).

This patient eventually had SMP to the entire scalp and covered his FUE scar and strip scar with great results. In the process he came to know and befriend Dr. Pak to trust his work. So after about a year he came back to Dr. Pak for a FUE procedure (about 1500 graft) to add density to the top and soften (corrective surgery) his front hair line from the old transplant work.

While the FUE transplant didn’t give him the full density, the SMP provided a cosmetic benefit to provide a look of fullness. Now he has the option to shave or grow his hair out long.

After 5 years, this patient came to see me to show me the transition of his new look. Considering the degree of balding he had when he came in, his results were spectacular. He did comment that no one ever noticed the change from a bald look to this hairy look. That is what surprised him most. The two pictures tell the story without words.



Doctor Rassman I want to know something about grey hair. Is grey hair caused by stress or simply genetics?

Block Quote

Probably a little of both. Some people almost never go grey. Some people, even in their childhood years have grey hair. Some have total white hairs (Santa Clause). People with little or no stress get grey hairs. There is no clear cut rule.

Aging has a part to do with it as well. If you think about it from a scientific approach with genetics as a partial cause, we all have a certain programmed destiny of the cells in our body. Environmental factors may alter some of this destiny but the point is that if the hairs go through several life cycles (anagen catagen telogen) over a person’s life some of those hairs may be pre-programmed to fall out and never regrow after an “x” number of cycles. Some may be pre-programmed to turn white or grey after an “y” number of cycles. This may be a simplistic way to view biology but it may help understand the variation and why some may lose hair or have hairs that turn grey.


Hi, I went to see a ISHRS physician 7 months ago because I was concerned about family history. He told me he didn’t see anything but told me to come back in 6 months. I recently went back and he examined my crown and mid scalp and found miniaturization, however I am still a NW1. He confirmed I have MPB, and gave me Finasteride. My question is, provided finasteride works, can I expect to keep this hair for a while? My thinning is unnoticeable to the naked eye but is present on a microscope.

Block Quote

I think you should ask this to your doctor since they examined you. If you have signs of male pattern balding (MPB), then finasteride 1mg (Propecia) is a medication to treat this condition. The thinning may not be detectable to the naked eye but it may be present under a microscope with signs of miniaturization. This is why we have always advocated the miniaturization (microscope) test. You can also consider a Bulk Measurement as well which is fairly accurate in detecting very early balding using the HAIR CHECK instrument. It is not necessary if you already have the diagnosis, but it can still document the progress of the hair gain or loss.

I have been taking Finasteride for over 6 years. (I am 32 now) Over the last year or two I have been getting an intense pain when I ejaculate. The pain feels like it radiates from the base of my penis, then it dies down. It feels a bit like a burning sensation.

The pain doesn’t occur every time I ejaculate, but quite often it does. I wonder if this may be caused by Finasteride in some way – such as the drug’s effect on the prostate. The only other side effect I have noticed is watery semen.

Block Quote


Painful ejaculation may be a sign of serious medical issue such as sexually transmitted disease (especially the burning sensation), prostatitis, prostate cancer, etc. I doubt it is related to a drug side effect especially after 6 years but such reports of pain with ejaculation are appearing over forums on the internet. As their appears to be legal actions taken against Merck (manufacturer of Propecia), the motivation for such reporting may be questionable and I do realize it is a very sensitive topic for many readers. In any event, you need to see your primary care provider or a urologist to see if there are medical issues associated with this complaint.

I realize we answer many questions about side effects on Propecia here on Baldingblog. However, not all sexual or penis related symptoms are related to Propecia.

I’ve checked out Dr x’s website, and he claims that he can perform an FUE surgery with a transection rate of under 3 percent. I’ve read your article on FUE which was written near the end of 2007. In that article you mentions that “the transection rate by our NHI surgeons are still well within the 10% range for FUE and we make no pretenses that it is better than that routinely.” With Dr x’s experience and latest tools, has he overcome a major flaw within the FUE procedure?

Also Dr x is marketing a new device which he created to improve the FUE procedure.

Block Quote

Some doctors have big egos. Some claim to have a better mousetrap. I can not and will not comment on another doctor’s claims. There are now robots doing FUE with good success and low transection rates that are evaluated by independent third parties and trusted researchers. There are no independent judges or observer who can verify claims. You are stuck to doing your own research and then trusting that the doctor you selected was honest with you.

The transection rate with FUE depends upon the skills and experience of the doctor, the instruments used and in many cases, the tissue make-up of the patient’s collagen. where the doctor (or robot) has no control. In the later case, it is individual PATIENT dependent.

I would guess that normal transection rates still vary in the hands of good, experienced and honest surgeons, number less than 10 percent transection rates. The transection rate is not the critical element in an FUE procedure, rather it is the experience of the team in managing the grafts. Even with the Artas® robot, other than the coring of the grafts, the rest of the process is manual, so manual quality control processes determines the success or failure of graft growth. I have recently seen a patient who had FUE with the Artas® robot, and the procedure largely failed. Even if the transection rate was very low, the detail in the manual management of the grafts may have been an issue. Did you know, for example, that if a graft is left open to the hair for as little as 10 seconds, it will die. That death, will not be seen until 8 months after the transplant surgery is finished.

I’ve seen Dr. Pak’s FUE surgery and his transection rate is not infrequently less than 3%, however, on the rare patient who has ’tissue’ differences in their collagen, the transection rate may go up to as high as 10%. We could ignore this singular result and report transection rate of under 3%, but that would not be honest. Our efficiency with FUE using our own internally developed tool is higher than most doctors in the world. It is not unusual for us to extract FUE grafts at the rate of 1,000-1,500 grafts/hour. We run an ‘open shop’ (open door policy) here which means that we hold open house events every month where our patients, happy or unhappy, can come to meet with people like you. Few doctors are that open with their patient population.

I realize for marketing purposes and advertising to the public these numbers and stats would seem important, but I would rather that your ask to meet some of his patients and get the doctor’s results from the patient’s own mouth as well as see the results with your own eyes.
