Study Confirms Importance of Dermal Sheath Stem Cells in Hair Growth Cycle

Colony of self-renewing dermal sheath cellsColony of self-renewing dermal sheath cells

New research published in the journal Developmental Cell has confirmed the importance of dermal sheath stem cells in maintaining the hair growth cycle. These cells, located around the lower portion of growing follicles, form the basis of an experimental treatment, being developed by Replicel Life Sciences, Inc., to regenerate hair-producing follicles. If successful, the treatment will be a game-changer for the hair restoration industry.

Caffeine Reverses Androgenetic Alopecia, Promotes Hair Growth in Cell-Cultured Hair Follicles

Hair loss caused by androgenetic alopecia can be stopped by existing medications, but to date, only two FDA-approved drugs are available for treatment of AGA: finasteride (Proscar ®) and topical minoxidil (Rogaine®). Unfortunately, up to 3 out of 10 individuals will not respond to one or more of these drugs. Because of this, researchers have searched for alternate treatments, especially for women since finasteride is not approved for use in female patients.

What is Lichen planopilaris?

Q: What is Lichen planopilaris? — G.S., Pleasantville, NY

A: Lichen planopilaris (LPP) is a distinct variant of cicatricial (scarring) alopecia, a group of uncommon disorders which destroy the hair follicles and replace them with scar tissue. LPP is considered to have an autoimmune cause. In this condition, the body’s immune system attacks the hair follicles causing scarring and permanent hair loss. Clinically, LPP is characterized by the increased spacing of full thickness terminal hairs (due to follicular destruction) with associated redness around the follicles, scaling and areas of scarred scalp.

Japanese Researchers Bioengineer Hair Follicles from Stem Cells, Dermal Papillae

Japanese researchers have demonstrated that scientists can bioengineer viable, hair-producing follicles from epithelial stem cells and dermal papilla cells. Using these components, the team produced follicles that exhibit both the normal hair cycle and piloerection (the reflex contraction of a tiny muscle in the hair follicles which creates what is commonly referred to as “goose bumps”). The bioengineered follicles also developed the normal structures found within follicles and formed natural connections with skin tissues, muscle cells, and nerve cells.

RepliCel Hair Cloning Research Leads To Patents, Trials In Humans

RepliCel Life Sciences; a company based in Vancouver, Canada; is investigating hair cloning techniques in order to develop a treatment for androgenetic alopecia, or common genetic hair loss.

Research conducted by the company’s scientific founders and lead scientists, Drs. Kevin McElwee and Rolf Hoffmann, has shown that a certain type of cell, called a dermal sheath cup cell, is integral in initiating the growth of mature hair follicles. This mechanism of follicle growth, when coupled with previous research on dermal papillae cells, is key to our understanding of hair loss and is a potential avenue for developing a treatment that could reverse hair loss.

Prostaglandin Discovery May Lead To Hair Loss Treatment For Men And Women

Miniaturized human hair follicle shows concentration of Prostaglandin D2 (in green). Credit: Garza and Cotsarelis/Penn Medicine)Researchers at the University of Pennsylvania, who were investigating the biological causes of androgenetic alopecia or common genetic hair loss, have discovered that levels of a certain inhibitor protein, called Prostaglandin D2 (PD2), are elevated in bald areas on the scalp. This discovery could be an important breakthrough in developing a medical hair loss treatment that regulates the production of the protein, or one that blocks it from attaching to its receptor protein.

What Does Hair Transplant Procedure Do To Existing Hair?

Q: What does the hair transplantation process do to your existing hair? — R.V., London, UK

A: When we perform hair transplant surgery, we transplant into an area that is either bald or has some existing hair. The hair that is existing is undergoing a process called miniaturization. What this means is that the hairs are continuing to decrease in size – both in diameter and in length. When we perform a hair transplant, we don’t transplant around the existing miniaturized hair on your scalp, we transplant through it. And the reason why we do that is because the miniaturized hair, the fine hair that is being affected by DHT, is eventually going to disappear, so you don’t want there to be any gaps.

What is the Difference Between NeoGraft and ARTAS Robotic System for FUE Hair Transplant Surgery?

Q: What is the main difference between NeoGraft and the ARTAS robotic system? — H.T., Staten Island, NY

A: The Neograft device is basically a powered FUE tool. It is still done by hand and therefore risks operator induced errors and damage to hair follicles. The ARTAS System, made by Restoration Robotics, uses electronic image-based tracking capabilities to map the individual follicular units. It does so to determine the optimal approach for automated graft harvesting. The robotic harvesting device produces consistently high quality grafts and low dissection rates.

Can Dandruff Or Nizoral Cause Hair Loss?

Q: Can dandruff cause hair loss? I have a lot of dandruff and use the Nizoral Shampoo for it. And can the Nizoral be a reason I am losing my hair? — K.P., Suffern, NY

A: Dandruff (the medical term is seborrhea) does not cause hair loss as it is a condition that involves scaling and redness on the surface of the scalp and does not involve the growth parts of the hair follicle that lie deeper in the skin. Although Nizoral is an ineffective treatment for hair loss (it is sometimes prescribed for this) it will not cause hair loss.

Is Nizoral An Effective Hair Loss Medication?

Q: I use Nizoral for my dandruff. Does it work for hair loss too? — M.D., Danbury, CT

A: The active ingredient in Nizoral is Ketoconazole. This medication, originally developed to treat fungus infections, has slight anti-androgen action. It is supposed to work in hair loss by inhibiting the action of DHT on hair follicles. Although, in theory, it should be useful for androgenetic hair loss, there have not been conclusive scientific studies to show that it works to treat balding when used as a topical application for balding.

Hair Loss Cure A Possible Result Of Stem Cell Communication Research

Following some new research on stem cells, and their relationship with androgenetic alopecia (genetic hair loss), an article on stem cells and the way they organize hair growth was published in the April 29th issue of the journal Science. At issue is the way in which large numbers of stem cells coordinate the cycle of hair growth over thousands of hair follicles. How do all of those hair follicle stem cells know when to grow hair, and how do they know what their “neighbor” hair follicles are doing?

Does Sebum Cause Hair Loss By Blocking Pores On Scalp?

Q: I have been on finasteride for about 7 months. After my latest haircut I can see that my scalp is shiny. I read that is from sebum buildup and it can cause a layer that clogs the growth of hair. I was wondering if this is true and, if so, how can it be treated? — T.C., Philadelphia, PA

A: It is not true. Hair loss is caused by the miniaturizing effects of DHT on the hair follicle, not by blocked pores.

What are the Obstacles to Hair Cloning Using Plucked Hairs?

Q: What are the possible obstacles that you see with hair cloning using the plucking technique? — D.E., Boston, MA

A: Plucked hair does not contain that much epithelial tissue, so we do not yet know what the success of the procedure will be. Plucked hairs will most likely grow into individual hair follicles that are not follicular units and therefore, will not have completely the natural (full) look of two and three hair grafts. This limitation may be circumvented, however, by placing several hairs in one recipient site. It is possible that the sebaceous gland may not fully develop, so the cloned hair may not have the full luster of a transplanted hair.

The most important concern is that, since the follicle is made, in part, by recipient cells that may be androgen sensitive, the plucked hair derived follicles may not be permanent. It is possible, that since all the components of a normal hair may not be present, the cloned hair may only survive for one hair cycle.

Since the ACell extracellular matrix is derived from porcine (pig) tissue, the procedure may not be appropriate if you are Kosher or allergic to pork. Of course, we do not know what other obstacles may arise since this technique is so new –- or even if the ones mentioned above will really be obstacles at all -– only time will tell.

What is ACell for Hair Cloning?

Q: I’ve read about some recent advances in hair cloning techniques with ACell. How does this work? — C.A., Stamford, CT

A: We, and several other groups, are engaged in studies using ACell MatriStem, a porcine extracellular matrix (ECM), to induce hair follicles to multiply in the patient’s own scalp (in vivo). This process differs from what people normally think of when speaking about cloning, namely producing populations of genetically identical cells, organs, or even individuals, in a test tube (in vitro).

In the current studies, a part of a hair follicle is implanted into the scalp in an extracellular matrix (ACell MatriStem), with the goal of inducing a complete follicle to form.

The concept is that if a small enough part of the donor follicle is removed, it will completely regenerate. Then, ACell MatriStem will induce the new hair fragment, implanted into the recipient site on the top of the scalp, to produce a new follicle –- thus we get two hairs from one. In one model being tested, hair is literally plucked from the scalp carrying with it enough genetic tissue to grow a new hair.

Why Am I Losing Hair Despite Taking Avodart For Hair Loss?

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.

Cutting Up 5mg Finasteride Tablets

Q: Hey doc, you told me to cut up 5mg finasteride into four parts. Why not five, so that it will be equal to Propecia which is 1mg? — H.F., Eastchester, NY

A: For several reasons; 1) you will lose some in the cutting process, 2) the generic dose can be slightly less than the brand, and 3) it is too difficult to cut into five parts – four is hard enough. Note that due to the fact that finasteride stays in the hair follicle for a long time, the pieces do not have to be in four equal parts.

Is Hair Cloning Technique Using ACell a Breakthrough?

Q: I just read a press release saying that researchers have developed a successful technique to clone hair by using a wound healing powder called MatriStem MicroMatrix. Is this new technique really a breakthrough in hair cloning? And if so, when can we start cloning hair?

A: It appears from preliminary studies that plucked hairs stimulated by ACell are in some cases able to regenerate new hair. Because the hair is placed into the recipient area and is partially derived from cells in the dermis, it is not yet clear whether the hair will be effected by androgens over time or if it will continue to bald.

The research so far is promising and a number of doctors are doing research in this area, including Dr. Schweiger and myself at Bernstein Medical – Center for Hair Restoration.

Why Does A Hair Transplant Work?

Q: Why does a hair transplant grow – why doesn’t the transplanted hair fall out? — J.F., Redding, C.T.

A: Hair transplants work because hair removed from the permanent zone in the back and sides of the scalp continues to grow when transplanted to the balding area in the front or top of one’s head. The reason is that the genetic predisposition for hair to fall out resides in the hair follicle itself, rather than in the scalp. This predisposition is an inherited sensitivity to the effects of DHT, which causes affected hair to decrease in diameter and in length and eventually disappear – a process called “miniaturization.” When DHT resistant hair from the back of the scalp is transplanted to the top, it will continue to be resistant to DHT in its new location and grow normally.

Is Lgr5 Gene Discovery a Hair Cloning Breakthrough?

Q: I heard about the Lgr5 gene being a breakthrough in hair cloning. What’s the latest on that?

A: Many scientists feel that adult stem cells house the answer to cloning (regeneration) of hair follicles. One of the problems of hair cloning, however, is that the cells, once duplicated, “forget” that they are hair follicle cells.

It has recently been discovered that the Lgr5 gene, located in stem cells, appears to contain the “global marker” present in all adult hair follicles. If Lgr5 gene is the “calling card” of the cell, it may carry the cell lineage and shoulder the responsibility of signaling to surrounding stem cells what they are actually supposed to do as they multiply.

After a Hair Transplant What are the Effects of DHT on Donor Hair?

Q: Hi! I wanted to ask if after a hair restoration surgery the transplanted hair will eventually fall out? Because the surgery is to restore hair mainly for people with genetic hair loss which results from DHT, won’t the DHT make the new follicles implanted fall out as well? — B.C., Stamford, C.T.

A: Hair loss is due to the action of DHT (a byproduct of testosterone) on hair follicles that cause them to shrink and eventually disappear (the process is called miniaturization). The follicles on the back and sides of the scalp are not sensitive to DHT and therefore don’t bald (miniaturize).

When you transplant hair from the back and sides to the bald area on the front or top of the scalp the hair follicles maintain their original characteristics (their resistance to DHT) and therefore they will continue to grow.

Laminin-511 Stimulates Dermal Papilla for New Hair Growth

Through this study, it was shown that the signaling pathways introduced by the administration of noggin and sonic hedgehog alone were insufficient to develop a hair follicle. When Laminin-511 protein was introduced to the tissue culture, the dermal papilla developed. When the protein was inhibited, hair follicle growth again ceased. This information supports prior studies suggesting that Laminin is critical in the early stages of follicle cell development and is required for continued follicle development and growth.

Strategies for Follicular Cell Implantation

Follicular cell implantation (FCI) is based on the ability of the dermal papilla (DP) cells, found at the bottom of hair follicles, to stimulate new hairs to form. DP cells can be grown and multiplied in culture, so that a very small number of cells can produce enough follicles to cover an entire bald scalp.

In order to produce new follicles, two types of cells must be present. The first are Keratinocytes, the major cell type in the hair follicle, and the second are dermal papillae cells (DP) which lie in the upper part of the dermis, just below the hair follicle. It appears that the DP cells can induce the overlying keratinocytes to form hair follicles. There are a number of proposed techniques for hair regeneration that use combinations of cells that are implanted in the skin. The two major techniques involve either transplanting dermal papillae cells by themselves into the skin, or implanting them with keratinocytes.

How Does the Laser Therapy (LLLT) Hair Loss Treatment Work?

Q: I heard about the laser comb and other lasers for hair loss, how do they work?

A: Low Level Laser Therapy (LLLT) is based on the scientific principle of photobiotherapy. Photobiotherapy occurs when laser light, absorbed by cells, causes stimulation of cell metabolism and improved blood flow.

Although the exact mechanism by which lasers promote hair growth is still unknown, they appear to stimulate the follicles on the scalp by increasing energy production and partially reversing the miniaturization process leading to thicker hair shafts and a fuller look.

Do You Use Sutures or Staples in an FUT Hair Transplant?

Q: Can you please comment on the use of sutures verses staples in hair restoration procedures? — S.S., Prospect Park, NY

A: Sutures are great on non-hair bearing skin and allow perfect approximation of the wound edges, but on the scalp they can cause damage to hair follicles below the skin’s surface. The reason is that a running (continuous) suture traps hair follicles and when the skin swells (as it normally does after hair transplants) the trapped follicles can strangulate and die.

After Hair Transplant, What Happens if Transplanted Area is Injured?

Q: I am a patient of yours who had a hair transplantation procedure done mostly in the crown area and in the front about seven months ago. The hair is just starting to come in nicely and is starting to fill in the bald spots. Yesterday I carelessly banged the top of my head against a beam in my attic and cut a nice gash in, you guessed it, a transplanted area. I’d say that the cut is about a good inch. My wife works for a doctor who is certified in facial plastic surgery and I had him suture up the gash. He did not cut any hair, but it took 4 stitches to close the wound. I’m worried about the impact on the transplanted area. Just when it was starting to come in nice I now have a bald spot that I suspect is going to stay as a result of the accident. Please advise. — V.F., Fort Lee, N.J.

A: There is not much you can do at this time. Depending upon the doctor’s suturing techniques; you may or may not have permanent hair loss from the trauma and subsequent suturing. The problem is that if the sutures are placed too far from the wound edge they can strangulate hair follicles, particularly if there is any swelling. Hair loss may be temporary, but if it is permanent, it should be minimal. Additional grafts can be added at your next hair restoration procedure to cover any area of hair loss and the scar from the injury, if it is visible.

Which Gives More Donor Hair: FUT or FUE Hair Transplant?

Q: I am Norwood Class 6 and have read about both Follicular Unit Extraction (FUE) and Follicular Unit Transplantation (FUT). Which will give me more hair? — D.D., Highland Park, T.X.

A: In general, FUT will give you more hair since, in FUT, the best hair from the mid-portion of the permanent zone of the scalp (also called the “sweet spot”) can be utilized in the hair transplant.

With FUE, since only the hair follicles are extracted and not the surrounding bald skin, if too much hair is removed, the donor area will begin to look thin as hair is removed. This will limit the amount of hair that can be harvested.

Although in FUE additional areas of the scalp can be utilized to some degree, this will generally not compensate for the inability to access all of the hair in the mid-permanent zone and the total amount available for the hair restoration will be less.
