Thank you for the time and effort you put into answering all of our questions. My question regards scarring. I have heard some people say that scar tissue forms where the hairs are implanted during a transplant, and that this can result in bumps or raised spots on the hairline. Is this true? If so, is it common? If not, why don’t scars form where the hairs are implanted? After all, a wound of sorts must be made to implant the hair, so how would do you prevent hundreds or thousands of scars from forming after a hair transplant?

With the technique we pioneered, we do two things that minimize recipient site scarring —

1. We make very small wounds in the skin, essentially slits that approximate the size of the grafts. These heal very fast.
2. When preparing the grafts for implantation, we cut off the skin disk at the skin level. To minimize the skin disk, we remove the top layer of the graft skin from the surface of the graft. This prevents the skin from surviving the transplant which could, in some individuals, produce the bump seen in recipient areas. The same process is done with grafts taken from strip surgery.

When doctors use grafts that have a larger surface area than what I described above, the bumps you referenced get more prominent. We have seen from the old days when plugs were done and the graft sizes ranged from 3-5 mm across, the skin always was deformed. Clearly the more skin that survives at the top of the graft, the more detectable will be the existence of the transplanted graft.

Dear doctor how are you? In terms of demographics, I have read on this site the older you become the more hair loss you see. For example, when somebody hits their 30’s, 30% of the people are bald when somebody hits their 40’s, 40% of the people are bald etc. etc.

Could there also be a reversal of those statistics? For example, once a person hits their 30’s and they are not bald or only have minor thinning, 30% chance that they will not go bald and once in their 40’s, 40% chance they will not go bald etc. etc. I know its really hard to judge because everybody is different, but I just wanted your input and wanted to share it with the rest of the readers.

Thank you for a wonderful website site. Take care.

Most balding occurs in men when they’re in their 20s, especially if they are destined for a more advanced hair loss pattern (Class 5 and higher). I can try to predict your pattern during an office visit by measuring your hair bulk and comparing it throughout the scalp. Early patterns that can not be seen with the naked eye can be measured and followed as you get older.

It is important to make your question personal, as none of us fall in any particular percentile, as it is just a statistical process.

My fiance and I are planning on trying to start a family in a few months (after the wedding). I’ve read in some places that Rogaine can lower sperm quality or affect an unborn fetus somehow, but I can’t find it anywhere that looks official. Is there any truth to this? If I do stop using it, will a large portion of my hair fall out within weeks? I’ve never gone more than a day without using it.

I’ve been on Rogaine for about three years now and it appears to have slowed my hair loss. If the choice is between keeping my hair and the health of my unborn child, obviously I’ll pick the latter. But I’d rather not have to choose. Thank you!

Rogaine (minoxidil) should have no effect on your sperm, nor have I have read anything supporting what you read about it affecting the fetus. Of course, if you’re concerned you should talk to your doctor.

Perhaps you’re confusing it with Propecia (finasteride), which has rare side effects related to ejaculate and fertility (but not change sperm count).

Hello Doctor

I’m a 27yo male with a full head of hair yet. I comb my hair a couple of times a day after my minoxidil application with a wide tooth comb. As I have medium length hair sometimes knots are formed and even if I’m gentle sometimes I feel little painful pulls.

Should I be worried about those? I doubt any hairs are being pulled out by the root because I try to be gentle, but if some hair does, will it grow back?

Thank you very much.

If you’re being gentle, I don’t know what to tell you. You could try switching to the foam instead of the liquid solution and see if it helps.

Hi Doc,

Nice blog.

My question is kinda odd, but please humor me. I can tell there’s some sort of relationship of importance between cause-driven itchy scalp and hair loss.

I really think someone in the hair loss research field, such as yourself, should look further into what I’m saying. I am a statistician by background; I have a PhD in my field, and I am by no means bringing up a crazy idea here. It’s a theory. We all want a cure for baldness, and the best bet is to hear out every conceptual idea or theory. If you could learn the connection here, I believe you would not only make a lot of money, but you’d also help a lot of people.

So, here goes… I noticed about a year or two ago – when I eat something spicy, my head itches. Ok, big deal. Sometimes when I workout, my head also itched. However, the spice aspect, is more noticeable, regular and I can even predict it. When I eat something spicy, I know I’ll have an itch shortly “only in the area of my head that’s thinning or balding”. It’s really strange, and my statistics background tells me there’s got to be a connection there.

The questions I think need answering are:

-Why do humans feel itching?
-What in a spice could cause itching at distant location?
-Could it be something from the spice goes into the bloodstream right away and effects DHT?

I seriously think a dermatologist should be able to answer this. I know I’m not the only one to bring this up.

I am not a dermatologist, so I will try to answer to the best of my capacity. I do know from personal experience that one of the consequence of eating spicy foods is sweating on the scalp, which can make your scalp itch. It also makes my nose run and sometimes my eyes water depending on the heat level. This may be due to a histamine reaction from the capsaicin, the chemical which makes it spicy. But I do not see how this is related to hair loss.

Most male hair loss is due to genetic causes, which is known as androgenic alopecia (AGA) or male pattern baldness (MPB). It is really not a DHT issue in and of itself. In other words, if you do NOT have the genes for hair loss, you will not go bald no matter how much DHT you have.

As far as why humans have to feel the sensation of itching, that is like asking why humans have to feel the sensation of pain. I think that is a bit beyond the scope of BaldingBlog. Sorry.

First of all I, among many other really appreciate your work in helping people out with hair loss questions.

My condition, starting at 18 (two years ago) began abruptly with hair falling out at all parts of the scalp. This includes the “donor area”, sideburns, the top, the crown, the sides…everything. I researched and thought it may have been telogen effluvium but it never stopped which led me to the unfortunate conclusion that i was losing ALL of my hair. Two years later it is still going strong with all parts of my scalp significantly thinned but no receding hair line at all. This past year alone I have been having constant, very serious dandruff ( to the point where I don’t even understand how my skin cells keep up with all the skin shedding) and toward my hairline it almost looks like a rash where the dandruff begins. I feel like either the dandruff is causing hair loss or the hair loss is causing dandruff.

Anyway, I am just wondering if you have any knowledge of this and if there is any sort of treatment just to at least give me some extra tie with my hair since I’m am not even 21 yet! My mother’s father lost all of his hair by 30 but since much time has passed there must be some sort of working treatment other than minoxidil and propecia. I am also 100% Italian if that helps at all. Any thoughts at all will be extremely helpful since I am too scared to tell my parents or anyone because I am so young!

Thank you

You need to see a good doctor. If you are losing hair in the donor area and the sides (as well as elsewhere on your head), you might have diffuse unpatterned alopecia (DUPA)… or there could be something else entirely (allergy? fungus?). It would be foolish to treat yourself and second guess what is going in.

You’re 20 years old, but you’re never too old to lean on your family for support if you need it. I’d start with a doctor to help determine what is causing your hair loss.

Hello Dr Rassman.

Want to start by thanking you and all the others who helped and contributed to this awesome forum!

I have been depressed for a while now. But then I’m very critical of antidepressants. So i have decided to test ST. John’s wort, who according to studies can be just as effective as antidepressants while it has much less side effects than conventional antidepressants.

But St. John’s wort has a tendency to affect the metabolism of other drugs.

My question is, do you know if St. John´s wort will affect propecia

I am not much of a herbal expert, but I do know that some herbs can interact with medications. In particular, St. John’s Wort is listed as having interactions with Propecia (finasteride 1mg), though I do not know if this will have a clinically significant affect on the efficacy of Propecia. You may run the risk of increase side effects, however.

I would consult with your doctor.

I was listening to the Joe Rogan podcast and was really surprised when he mentioned that he won’t shave his head because he had a transplant a few years ago and has a scar. I always wondered why he DIDN’T have a transplant when I would see him on TV but was kind of surprised that he says he had one. Do you think he was misinformed as to what his eventual loss would be?

Your guess is as good as mine. I do not know the circumstance of actor/comedian/host Joe Rogan’s hair loss or the treatment he had. It’s possible that he had the surgery many years ago and had continued hair loss, but I really don’t know.

Someone might mention to him that we can treat his scar with either a scar revision or Scalp MicroPigmentation (SMP).

IDOC.. let me see if I have this correct. Having a transplant in an area where there is still a fair amount of hair increases the odds of shock loss? if i want to get a head start and restore my hairline as its thinning but still have hair, the trauma from the surgery will most likely cause shock loss to the existing hair in that area. Is that right? So the best candidate is one who has little hair in the area to be transplanted?

Is anyone still testing A Cell therapy for hair restoration?

Thanks

Those who are at the highest risk for shock loss include:

1. Patients with noticeable hair loss that is active at the time of surgery
2. Patients that are younger than 30 years old
3. Patients that have significant miniaturization of hairs in the balding pattern.

When such patients are on finasteride, the risk for shock loss is reduced.

I know I sound like a broken record at times, but everyone is different and every individual case is unique. There is no universal answer to this question. Some wait until they are bald before they have hair transplant surgery. Some have surgery as they are balding (to maintain their existing look). Shock hair loss is always an issue, but not an overriding one after all the factors are considered… as long as you and your doctor are realistic about shock hair loss. Some overreact or misinterpret what shock hair loss really is, and make it out to be an overbearing issue. But this is a generalization. Please read this recent post on shock hair loss. We do take it seriously, but we also take it on a one-on-one basis. That is why we have a real doctor- patient examination and consultation before any surgery.

With respect to ACell, we have conducted the one year study for hair restoration, but it was a failure. As far as I know, no doctor has been able to reproduce the results claimed by Dr. Hitzig or Cooley on hair multiplication. That is probably why you are not reading about it in scientific journals or in the mainstream media as the next great breakthrough. I don’t know which doctors are still experimenting with it, though.

Can I use hair removal if I decide my transplants just aren’t looking right? I am just trying to figure out what my options are to undo the surgery.

I met with a patient a couple years ago who had frontal hair transplants at a clinic with results that did not meet his expectations. He responded by going through electrolysis and removing the grafts. He came to my office to figure out what to do with the linear scar.

The results of the tedious electrolysis was very good, but in our experience, electrolysis is very dependent upon the skill of the person doing it. The means the results from this process can vary considerably. The use of hair removal lasers also can be a problem particularly if the grafts are large since they leave an abnormal “foot print” in the skin once the hair is gone.
