Estrogen and Hair Loss in Men

Thursday, May 1st, 2008

Q:

I have heard high estrogen in males can contribute to hair loss. Is that true? I am a 40 year old man with low sex drive and female patterned hair loss.

A:

High levels of estrogen in men could be seen in many other conditions such as estrogen-producing tumors, congenital adrenal hyperplasia, chronic alcoholism and advanced liver disorders. Elevation of estrogen in men can cause sexual dysfunction, change in body fat distribution in a female pattern and breast enlargement and secretion.

Balding is not a typical sign of excess estrogen. In fact one of the signs of estrogen deficiency could be hair loss in female patients. A common type of this kind of hair loss is seen in telogen effluvium that women lose hair due to sudden drop of estrogen and progesterone levels. Although excess estrogen is generally not the trigger for hair loss, it can affect the balance of other hormones and indirectly cause hair loss. The latter is not a common cause of hair loss in men or women though.

Hair Loss Treatment with Dutasteride

Tuesday, April 29th, 2008

Q:

Hi Doctor,

Some doctors prescribe Dutasteride (Avodart) for hair loss prevention. I know you do not recommend Dutasteride for hair loss for obvious reasons, but based on available research findings on this medication, what do you think are the most likely possible side effects from using Dutasteride if worse come to worse. Would it be like multitude of finasteride side effects? Again, I know your view of non-FDA approved drugs.

A:dutasteride

Dutasteride (Avodart) is one of the selective inhibitors of the type I and II of the enzyme 5-alpha-reductase, the enzyme that converts the male hormone testosterone to 5-alpha-dihydroxytestosterone (DHT). In comparison with dutasteride, finasteride (Propecia) acts as an inhibitor of just type II of the enzyme 5-alpha-reductase, which is more specific. Studies around dutasteride mechanism of action shows that, blocking both type I and type II enzyme can be more potent that only one in reducing the levels of DHT in the body.

If you are taking dutasteride for other indications, you may get some hair growth as a good side effect. As you may guess cannot recommend dutasteride solely for prevention of male patterned hair loss; not until it is approved for hair loss treatment by FDA. Other than not being FDA approved my other reasons are:

  1. The optimum dose of dutasteride for hair loss prevention is not determined.
  2. The side effects of dutasteride are much more prominent comparing to finasteride.  That include the negative effect of the medication on sex drive in men.
  3. If you are considering the cost effectiveness of dutasteride, with new price reduction of finasteride that should not be in the picture any more.

Hair Cloning – Hair Multiplication

Sunday, April 27th, 2008

Q:

Is Hair cloning or multiplication being done anywhere yet?

hair follicle

A:

Hair cloning or multiplication has been in the news in the last few years. I prefer to use the term hair multiplication, rather than cloning because cloning refers to production of genetically identical organisms. Dolly the most celebrated sheep was the product of first cloning. When it comes to hair, we do not really clone the cells, but we culture them and try to get a whole organism from cultured cells. Unfortunately the process of culturing hair follicle cells has not been as simple as some other tissues in human body. The complexity of hair physiology is due to participation of many different stem cells in development of each hair follicle. In this process, we do not multiply genetic material or DNA of cells.

Hair cloning news

Hair multiplication if become a reality could bring about a great opportunity for bald people with violated donor scalp who cannot be good candidates for hair transplantation with current techniques. Despite our enthusiasm about hair multiplication, hair cloning news in last few years has not been filled with many success stories.

Hair cloning 2007

Year 2006 intercytex company announced that they are going to start phase 3 of hair multiplication study soon. Hair cloning has been in the news and many people are eagerly following that news to see when and how they can get a full head of hair using hair cloning techniques. Unfortunately, cloning hair has not been going that well and in last few years we only had limited research results on hair multiplication in animal models and in human. Here is the question that people usually ask me: Is hair cloning being done anywhere yet? And my answer usually is: Not except on experimental levels. Several investigations are in process on hair multiplication field and hair stem cell research.

Hair cloning 2008

Hair multiplication or as people call it hair cloning is a method that allows us to culture hair follicles and multiply it so we can increase the final number of hairs. So far, we know that it is doable on animals, and there are some reports of its feasibility on human volunteers. Safety has been one of the biggest questions on any research involved with stem cells. Stimulating growth of stem cells has always raised the flag for possible tumor formation. In year 2008, we should witness some results of the phase 3 studies on the procedure. During this year or in next few years, we should have a better understanding of the effectiveness and safety of hair multiplication. I know many of my patients are following hair cloning news carefully. Unfortunately, hair multiplication news has not been very fruitful in last year, but the process is complex and one way or another it will become clear in next few years that we can or cannot use hair multiplication methods in hair restoration surgeries.

Tretinoin and Minoxidil Combination for Treatment of Hair Loss

Saturday, April 26th, 2008

Q:

How are you doing? All I have to say is TGIF.

I was doing a little bit research on hair loss, and I stumbled over retinoic acid. I read about it and have a basic understanding. Have you heard any claims that it could possible revive hair loss?

Have a great weekend!

A:

Rogaine

This is a good question. There are several claims on therapeutic effect of all-trans-retinoic acid (tretinoin) alone and in combination with 0.5% minoxidil for hair loss based on limited studies.

In one study the combination of tretinoin and minoxidil was used for 56 patients who had androgenic alopecia (male pattern baldness) and hair growth was followed. The growth of terminal hair was studied after one year of treating balding scalp with combination of topical tretinoin with 0.5% minoxidil. Increase in hair growth was reported in 58% of the patients who could complete the study.

Although tretinoin has been stated as a promoter of cell proliferation and vascular creation, which are both important in hair growth, there is still not enough scientific evidence from large studies to prove these effects. Also double blind studies on the efficiency and adverse effects of the product is lacking.

Murad Shampoo for Hair Loss

Saturday, April 19th, 2008

Q:

Dear Dr. Mohebi,

Murad shampoo

I hope all is well with you and the family. I wanted to see your opinion about something. Along with proscar, I use Murad shampoo (i dont know if you have heard of it) but it supposedly strengthens your hair and brings nourishment to the hair, therefore promoting hair regrowth. Remember how short my hair was when we first met, well now its relatively longer. Do you think i should keep it short for several reasons: easier to clean my scalp, exposure to vitamin d (sunlight). When my hair is long, I can see it shed, but when its really short it doesn’t seem that way. However, the downside to cutting my hair that short is that it will become pretty apparent that im experiencing hair loss. Thanks doc! take care!

A:

I hope you are doing well. Last time we met, we decided that you wait on doing a hair transplant procedure until your pattern of hair loss becomes more obvious. Here are the answer to your questions in the order you asked them:

  • Murad shampoo has following active ingredients: Pomegranate extract, artemia extract, alpha hydroxy acids, phytantriol and Saw Palmetto. From all these only the last one or Saw Palmetto is proven for its anti hair loss properties through blocking DHT. However, the rate of penetration of this ingredient on deeper layers of skin where follicles reside is not completely clear. I don‚Äôt think it hurts to use it in general, but for someone like you who takes systemic form of DHT blockers (finasteride), I am not sure it can add anything in slowing your hair loss process.
  • On whether or not keeping your hair short, it is up to you, you have to try them both and decide, long hair should not create any problem with cleaning hair. Do whatever you are more comfortable with. Neither of the two can affect the speed of your hair loss. If I wanted to choose, I would kept my hair long so layering can help covering the thin areas.
  • Vitamin D could be absorbed from everywhere, especially in the sunny State of California.

Again, thanks for good questions,

Good Luck and have a great weekend
Dr. Mohebi

Toppik for Hair Loss

Saturday, April 19th, 2008

toppik

Toppik hair loss scam, does it really work? The fibers used by Toppik are made of the same material that hair shafts are made of and that is Keratin. The fibers of Toppik bond with hair and it’s nearly impossible with the naked eye to see that there is anything on your hair. It gives the appearance of fullness that you have a natural, thick looking head of hair. This is temporary because it does not grow hair but conceals it in the short term for a special meeting, date or party. Toppik is natural and safe and can eliminate the appearance of balding or thinning in only a certain group of patients.

The people who can get the most of Toppik are the ones who have hair with some degrees of miniaturization or thinning. If the hair is totally gone like in higher classes of baldness, Toppik does not help. Toppik needs some hair to be bond with to create the appearance of fullness.

Toppik - Scalp microscopic view

A scam is only realistic if you want to believe in it. We all know that hair loss is a bitter truth that affects many men. Men do anything to improve their appearance and hid their baldness. There are many methods that can help someone with hair loss to improve the appearance of his hair including hair transplant surgery and medical treatment for hair loss. Cosmetics like Toppik offer another way to deal with the hair loss problem.

Toppik for hair loss is a scam or not, does not really matter. The fact is that you should do whatever makes you feel better about yourself. Hair restoration is a proven treatment for psycho-social adverse effects of baldness. If you can use any other method such as Toppik to look better and feel better, why not trying it?

 

Hair Stem Cell Research Information

Friday, April 18th, 2008

Question:

Hello,

I’m very interested in learning about the future methods and advancements in the science of hair restoration as you may have guessed. Is there an “on line” information source you could direct me to, in order to keep of with the current work on stem cell progression, and the like? I have ushairrestoration.com site, of course, because it’s on your card. But am at a lose as how to get more information. Is there a site that publishes research papers and cases studies of new developments?

Answer:

I am not aware of any site that is dedicated to the advancements on stem cell research, but there are some sites that you can get good information on hair restoration and possibly get yourself familiarized with the new surgical and medical methods to restore hair. One that I recommend is the website of the International society of hair restoration surgery. It may not be updated very often, but is being fed through many different sources and could be a good source of information for someone like you to get some general information. Of course if you are interested in more scientific articles, you can use the National Center for Biotechnology Information, which gives you the most recent publication in most medical journals. This site is searchable for different criteria so you can put your keywords in and see what new information is out there.

Hair Transplant Scar

Thursday, April 10th, 2008

Hi Doctor,

My son has had a hair transplant years ago with old techniques and he has bad hair transplant scar now. He now wants to shave his head, but the scar of hair transplant on the back of his head may become exposed. Do you perform hair transplant scar repair or do you recommend any procedure that can help with hair transplant donor scar coverage?

Hair Transplant Scar

Answer:

Hair transplant with strip technique can cause a linear scar that could be visible on the back of head if the patient wants to shave his/her head. A hair transplant scar is not limited to a bad hair transplant technique and it might have to do with one’s personal healing process too (some people are generally better healers compared to the others).

The good news is that we have methods to minimize the size of the scars nowadays and if you have bad hair transplant scars from bad transplants in the past, there are several new methods that can help improving the appearance of the donor scar. A hair transplant scar could be improved by repair of linear widened scars with different methods that we perform at our Los Angeles office of US Hair Restoration. Dr. Mohebi is the inventor of the axometer, a device that measure the laxity of the scalp precisely before hair transplant surgeries. Good measurement of the scalp laxity is one of the best ways to minimize development of donor wound complications and widening of donor scar and the Laxometer is the device to do these measurements.

One method is through simply excising the scar. Excision of the donor scar may be helpful for some donor scars. After removing the scar, hair transplant surgeon can close the skin with the trichophytic closure method in which a small wedge on one or both sides of the skin edge is removed and the skin is closed primarily. Trichophytic closure allows some hair follicles to grow new hair into the final scar. Presence of hair helps making the hair transplant scar become invisible.

Hair transplant donor scar coverage could also be performed by transplanting hair into the scar. Hair could be harvested from other areas using FUE or mini-strip techniques. Again, presence of the hair inside scarred area could trick the discriminating eye and the scar would become less detectable. Patients may need more than one hair transplant procedure into the donor scar for minimizing the difference between the densities of hair in scar and surrounding areas.

The last method that could be used to camouflage the linear scar is by tattooing the scar. People who plan to keep the hair very short can easily tattoo the scar with the figures of short hairs so it seems that there are some hairs present in the scar area, which can help minimizing the visibility of the scar.

Mega Session Hair Transplant Surgery

Wednesday, April 2nd, 2008

Mega session hair transplant surgery has been around for almost a decade since Dr. Rassman and others started doing bigger and bigger sessions. Before 1993 all could be done was less than 1000 and occasionally 1500 grafts per each session. Using newer techniques and larger team of experienced technicians, we at US Hair Restoration are currently performing large sessions on a regular basis.

Not all physician teams are equal. If a doctor routinely performs sessions in over 2500 graft size, then it would be safe to assume that this doctor has mastered the skills required for large session. Unfortunately, not all doctors have either the teams or the skills to accomplish the feat on a routine basis. Limiting the size of the session to under 2000 grafts, it may take more surgical sessions to accomplish the same goal as when twice the number is transplanted.

Many factors should come together for a megasession hair transplant surgery. First, the surgical team must be trained in doing large sessions with fast, efficient cutting and placing. The following points must be available for the surgery to be successful. The sessions should not take more than eight to ten hours, for more than that, the grafts that are out of the body awaiting placement produces reduced graft growth. Hair transplant surgeon should keep a larger team of technicians to help reducing the time of surgery.

The surgeon must know the nuances of prolonged anesthesia without increasing the risks to the patient. The patient’s scalp laxity must be very loose so that a wide strip can be taken safely (often these strips measure greater than 2cm in width and 22cm in length). The patient’s density must be high (50% higher than normal densities). Large sessions might carry increased risk of swelling and redness after surgery, but overall are not more risky than smaller sessions, but the above criteria must be bet or the yield would not be there. At US Hair Restoration, we offer megasessions to patients with extensive baldness with good donor quality with excellent results.

Finansteride, Minoxidil Or Both

Saturday, March 29th, 2008

hey doctor!

As I read through forums and articles, people mention that propecia works better in conjunction with something else, such as rogaine for exmaple. At the moment, the vertex area of my scalp seems emptier than than the crown and minoxidil works well with the vertex. Do you recommend me go back on minoxidil for the vertex, or should I just focus on propecia?


Answer:

I generally prescribe finasteride to most of my patients who have significant miniaturization whether they are getting hair transplants or not. There are several studies on using Rogaine (minoxidil) and Propecia (finasteride) as single therapy and in combination with each other or with other medications.

Comparing minoxidil and finasteride for treatment of male pattern baldness clearly shows that treatment with only finasteride is more effective than treatment with only minoxidil. Combination of finasteride with minoxidil and with some other medications shows improved outcome, but the rate of improvement is not significant enough that I can convince myself to prescribe combination therapy to all my patients for the rest of their lives, considering difficulty of using topical minoxidil (topical spreading of medication twice a day on the balding area of scalp).

If you want to do everything possible to prevent or slow down further hair loss and maybe grow some, you can consider combination therapy, but remember when you start minoxidil you are committed to continue it for the rest of your life or until there are better alternatives.
