Sometimes an “accident” in the laboratory can lead to a remarkable breakthrough. Penicillin, Botox, Viagra, and Minoxidil — the active ingredient in Rogaine — were all unintended discoveries that led to treatments for a variety of conditions.

A similar twist of fate, this time by researchers at UCLA, could lead scientists to a new hair loss treatment.

Mice had been bred to overproduce a stress hormone that causes them to lose their hair. The scientists’ intention was to study the effects of a chemical compound, called astressin-B, on blocking the effects of stress on the mouse colon.

What they saw, however, surprised them. The mice that were treated with the chemical had fully regrown their hair. After repeating the results, the researchers injected the chemical into young mice, which were similarly genetically altered but had yet to lose their hair. Those mice never lost their hair despite the fact that they, too, were bred to overproduce the stress hormone.

Whether this discovery will lead to a drug that cures common baldness in human beings, or whether such a cure will only affect hair loss due to stress, is unknown at this early stage.

For further reading on this discovery, see articles in Dermatology Times and the New York Times, as well as the primary scientific publication in the journal PLoS ONE.

Dr. Eric S. Schweiger - Associate at Bernstein Medical - Center for Hair RestorationDr. Eric S. Schweiger, board-certified dermatologist, is quoted in a few recent articles on the effects of chemotherapy on hair, genetic testing for hair loss, and protecting a balding scalp from the sun.

“Coping with Chemo-Induced Hair Loss” was published in a recent issue of Energy Times, a publication focused on wellness and nutrition. Dr. Schweiger commented on the way hair follicles can react to chemotherapy treatment for cancer patients:

Expect changes like “chemo curl.” Eric Schweiger, MD, explains that chemo shocks rapidly dividing cells like hair follicles in the scalp, causing the hair loss. “When the follicles grow again, the shock sometimes changes how they grow, temporarily resulting in a different hair texture and color, which eventually normalizes,” explains Schweiger.

In the article, “Genetic Testing to Predict Hair Loss,” published on HairLoss.com, Dr. Schweiger and Dr. Bernstein discussed the efficacy of genetic tests for hair loss:

[Dr. Schweiger] explains, “I think the test has probably identified a predictor of hair loss but not the only predictor. There is science behind the test and some published research studies; however, the longitudinal, larger studies have not been done, because this testing procedure is just too new.” Dr. Robert Bernstein, M.D., director at Bernstein Medical Center, agrees and adds, “These tests focus on one particular dominant gene, but what is becoming apparent is that hair loss is a complex genetic condition most likely involving several different genes.” He further notes that age, stress, hormone levels, disease and many other factors also are at play in determining factors for hair loss. “Just because a person has the genes for baldness, it doesn’t mean the trait will manifest itself. The truth is the cause and effect have not been proven and differ from person to person, and the association is not anywhere near 100 percent.”

[…]

“Right now, we predict future hair loss based on follicle miniaturization, using advanced microscopic equipment,” says Dr. Schweiger, “and I advise a man to do this at around age 25. If someone presents with more than 25 percent miniaturization, then it’s time to start a hair loss prevention regimen.”

Lastly, Dr. Schweiger contributed featured commentary to an article on HairLoss.com on a topic of importance to those suffering from hair loss, namely, protecting your scalp from the dangerous radiation given off by the sun. In “When You Lose Your Hair, Protect Your Scalp,” Dr. Schweiger encourages bald or balding individuals to take important steps to protect their scalps:

…if you notice your hair thinning or you have baldness of any kind for any reason, it’s important to protect your scalp from sun damage, precancer and skin cancer,” says Dr. Eric Schweiger, M.D., a board-certified dermatologist and hair transplant surgeon at Bernstein Medical — Center for Hair Restoration in New York City. That’s because 100 percent of the surface area on top of your head directly faces the sun’s burning rays when the sun is strongest, between 10 a.m. and 2 p.m. “In general, a mild sunburn on your scalp won’t harm your hair follicles. But any exposure that causes blistering can cause scarring and pre-cancer cells, which will harm hair follicles permanently, so you need to take special care of your scalp when exposed to the sun, even for only a few minutes,” explains Schweiger.

Q: I am currently taking Avodart and have done so for around 8 months. Last night I had a significant loss of hair after taking a shower, nothing like I have ever seen before and found it very distressing. Can you tell me if this is hair loss or could it be something known as shedding and could you please tell me what is the difference between hair loss and hair shedding? — M.S., New York, NY

A: Hair loss is a very general term that can refer loss of hair for any reason. Genetic hair loss is caused by the effects of DHT on hair follicles that result in miniaturization -– i.e. a slowly progressive change in hair diameter that starts with visible thinning and that may gradually end in complete baldness. Hair shedding is more sudden where hair falls out due to a rapid shift of hair from its growth phase into the resting phase. The medical term for this is telogen effluvium. This process is usually reversible when the offending problem is stopped. It can be due to stress, medication, or other issues. You should see a dermatologist to figure out which process is going on. Dutasteride can cause some shedding when it first starts to work, but it would be unusual to do this after being on treatment for eight months.

Q: Can stress produce diffuse unpatterned hair loss (DUPA), or was it bound to happen anyway? — D.D., Park Slope, Brooklyn

A: Both DPA (diffuse patterned hair loss) and DUPA (diffuse unpatterned hair loss) are genetic conditions, unrelated to stress and would have happened anyway. These types of hair loss are characterized by a high percentage of mininiaturized hair in broad areas of the scalp. See the Classification of Hair Loss in Men and Classification of Hair Loss in Women pages on the Bernstein Medical – Center for Hair Restoration website for more information on this topic.

In contrast, stress generally presents as increased hair shedding, a reversible condition referred to as telogen effluvium. It is called this because the normal growing hair is shifted to a resting (telogen) phase before it temporarily falls out. Increased miniaturization is not associated with telogen effluvium.

Q: I’ve been dealing with daily mental stress for the past few months. I’ve noticed that during that time, I’ve experienced a lot of frontal hair loss and thinning. I thought stress was a myth for causing hair loss. — R.P., Upper East Side, Manhattan

A: Stress may cause temporary shedding, but it generally does not affect the long-term course of genetic hair loss.

It seems that women’s hair is affected by stress more commonly than men’s hair, but the reason is not clear.

Q: Can stress accelerate hair loss? I am 25 and there is balding on my dad’s side of the family. I never had any thinning or hair loss till this year. I guess you can say I’ve been under a lot of stress. When I did notice shortly after my 25th birthday I started stressing even more, which led to more hair loss. It is thinner up front and it is thin on top. I have heard of some hair docs mapping your head for miniaturization, do you do this too? — E.W., Miami, FL

A: Yes. The presence of miniaturization (decreased hair diameter) in the areas of thinning allows us to distinguish between hair loss due to heredity (i.e. androgenetic alopecia) — in which hair progressively decreases in diameter under the influence of DHT — and other causes. The degree of miniaturization can be assessed using a hand-held instrument called a densitometer.

The pattern of hair loss and the family history are also important in the diagnosis.

Stress more commonly produces telogen effluvium, a generalized shedding that is not associated with miniaturization and is often reversible without treatment.

Q: Over the past three months, my hair seems to be thinning more on one side. Is it common in male pattern hair loss for it to be more on one side? I had a lot of stress about three months ago and have heard that this could be the cause. Is this possible? Should I use Rogaine to treat it? — B.R., Landover, MD

A: Regardless of the cause, hair loss is usually not perfectly symmetric. This applies to male pattern hair loss as well.

In your case, it is important to distinguish between telogen effluvium (shedding that can be due to stress) and hereditary or common baldness. The three month interval from the stressful period to the onset of hair loss is characteristic telogen effluvium, but you may have androgenetic alopecia as an underlying problem.

The two conditions are differentiated by identifying club hairs in telogen effluvium and miniaturized hair in androgenetic alopecia. In addition, a hair pull will be positive in telogen effluvium (when a clump of hair is grasped with the fingers, more than five hairs pull out of the scalp at one time) and will be negative in common baldness. The hair loss diagnosis can be made by a dermatologist.

Hair cuts do not affect either condition.

Rogaine (Minoxidil) is only effective in androgenetic hair loss and only marginally so. Finasteride is the preferred treatment if your hair loss is genetic when it is early and a hair transplant may be indicated if the hair loss progresses.

Shedding from telogen effluvium is reversible and does not require specific treatment.

Dr. Bernstein was interviewed by New York Newsday in their article, “It’s a Hairy Decision Picking a Treatment for Baldness.” The complete article is below:

HEALTH MATTERS COLUMN

Even IF they don’t talk much about it, just about all the guys he knows are taking medication for their thinning hair, said Steve, a retail manager in his early 30s from Suffolk County, NY. He would be too, but he had side effects right away. He’s had consultations for hair transplants, but that won’t work either because of the pattern of his balding.

So he’s using a protein product that makes his hair look fuller, changed his diet to include leafy green vegetables, gone to two psychics for help. And, he said, he’s biding his time, waiting for new hair restoration medications or for hair cloning to hit the marketplace.

“In the ’90s, everything’s about looks,” said Steve, who asked that his last name be kept confidential. “No one wants to give up their youth.” All the effort to find a hair restoration solution is worth it, he said, “because losing my hair bothers me a lot.”

Sure, hair loss isn’t crippling or life-threatening. But to hear people’s tales, it’s traumatic, depressing and embarrassing.

Yet, you’re more likely to get a snicker than a hug for your pains, said Spencer Kobren, 34, a Manhattan consumer activist and author of “The Bald Truth,” (Pocket Books, 1998, $6.99.) There may be few open arms to comfort you, he said, but there are plenty of extended hands to take your trust and your money.

Kobren should know. He has spent several years testing out hair loss products and talking to the experts about his own hair loss, which began at 22. Now he serves as a sounding board and clearinghouse for the good news and the bad about hair loss and its treatments on a syndicated radio show, aired locally on WEVD /1050 AM on Sunday nights.

“You feel like you’re losing a part of yourself. You see your appearance deteriorate, often rapidly and drastically,” he said. You become vulnerable to promises and pitches, but don’t be swayed by them, said Kobren, who now has a full head of hair. Instead, do a lot of research. The wrong hair restoration products or treatments may not only fail to grow hair, they can make matters a lot worse. For example, he said he gets thousands of letters and e-mails about botched hair transplants that leave men scarred, poorer and balder.

According to Kobren, about $7 billion is spent by consumers annually on finding solutions to hair loss. There are about 50 million men who are balding, with at least 20 percent starting in their 20s. Most have male-pattern baldness, genetically linked and triggered by the action of a hormone called dihydrotestosterone (DHT).

Hair loss is not just a guy thing, though. Plenty of women — about 20 million — have varying degrees of it too. Hair loss is finally getting recognition as a women’s health problem, said Maggie Greenwood- Robinson, whose book, “Hair Savers for Women” (Three Rivers), is due next spring. Kobren’s “The Truth About Women’s Hair Loss,” (Contemporary) will be out in January. “There are more options than ever before for women with hair loss,” said Greenwood-Robinson, and they shouldn’t give up.

But they do have to be cautious. The diagnosis and treatment for men and women is very different, said Dr. Robert M. Bernstein, assistant professor of dermatology at Columbia College of Physicians arid Surgeons and medical director of the New Hair Institute in Manhattan and Fort Lee, N.J.

“Women usually have a diffuse type of hair loss with thinning all over,” he said, “while men generally lose hair on the front and top and keep a permanent zone on the back and sides.” Female baldness can also be due to DHT, but many women lose hair because of anemia, gynecological issues, thyroid disorders or stress, among other reasons. You don’t want to waste your efforts on hair restoration products when what you need is more iron or different birth control pills. “A medical evaluation is extremely important to rule out underlying medical conditions,” said Bernstein.

The treatment of hair loss is an increasingly complicated decision for both men arid women, but at least there is more information than ever to help you ask the right questions. Web sites include www. thebaldtruth.org and www.regrowth.com. Bernstein’s practice has a Web site at www. newhair.com and a detailed book called “The Patient’s Guide to Hair Restoration.”

Your hair restoration options include:

Medication: Finasteride (brand name Propecia), taken orally by prescription. Available for under two years, Propecia is for men only and causes side effects in about 2 percent of them. It has been shown to stop hair loss in about 87 percent of users and new growth in about half. It’s not for women, because it can cause birth defects if a woman is pregnant, and if she’s past child-bearing age, it doesn’t seem to work.

Minoxidil: (brand name Rogaine), used topically. It can be used by both men and women and appears to slow down the rate of hair loss, but not to prevent balding in the long haul. Any effect from either of these hair restoration medications stops when you no longer use them.

Hair transplant surgery: for men and women. Bernstein has pioneered a state-of-the-art technique called follicular unit transplantation, a precise method using hair-follicle groupings that result in a more natural growth of hair and doesn’t leave scars.

Removing grafts of skin from your head and placing them in balding spots is clearly an art as well as a science. Besides being a good candidate for surgical hair restoration, you need to find a dermatologist with a lot of experience performing hair transplant surgery. Expect to ask many questions, learn the risks, see pictures of other patients and meet them in person.
