    Were the ACell injections just straight into the scalp, or were they used to aid transplantation?

Nor would I expect them to, because I am not extracting complete follicles.

    I've attached a photo of two single hair grafts from the same patient. The one on the right is plucked, and the one on the left is dissected from a strip. Both are single hairs from the same patient, so we're making a valid comparison. I chose the meatiest pluck I could get for this example. It even has the dermal papilla attached, which is quite rare for plucks. The difference is that the intact follicle on the left has the dermal sheath, which is quite apparent when you compare the width of these grafts. Also attached is a histologic stain of a plucked graft.....there is no dermal sheath on it. Hair will regrow at the plucking site because mesenchymal stem cells in the dermal sheath will regenerate a papilla, and epithelial stem cells in the isthmus will interact with this papilla to form a new hair fiber. Fifty years of basic hair research support this statement.

    Someone on this Forum mentioned how frustratingly slow hair growth studies can be, and I echo this. I am accumulating more clinical experience with this technique, and time will tell what role it will play. There are many very good questions and it will unfortunately take time to answer them. Later this year, I will provide an update on my results. In the meantime, I recommend patients seek out standard medical treatments and if they are a candidate, do FUT or FUE.

    Dr Cooley
    so is dr cole confused? how can his plucked hair be different than dr cooley's plucked hair? either way this seems incredibly promising and i would gladly wait few years if it actually works.

    yes the acell and prp were directly into scalp.I hear Dr.De Yarmann soaks grafts in acell when doing transplants as well.

    There are different results from plucking hair. if you pluck an intact follicle or a nearly intact follicle, you are not going to get regrowth in the donor area. As such, I continue to disagree with the those who feel that nearly intact follicles will result in regrowth of hair.

    A little bit of mesenchymal tissue is not enough to feel confident that a hair will regrow in the donor area.

    i do agree that patients should not depend on this "plucking" technology and focus on more traditional methods of restoring their hair at this time.


    If we suggest that we have a new FDA approved product that may be combined with plucked hairs and produce two hairs from a single hair, we may expect a euphoric response from both patients and physicians. When we have not demonstrated the capacity to duplicate hair, however, we should be careful to avoid the implication that we have discovered a means to clone hair. I’m not suggesting that Dr. Cooley and Dr. Hitzig will not produce subsequent evidence, however. In the interim, we should exercise greater caution.


    I suggest we stick to evidence based medicine that depends on the following: hypothesis, methods, and results, followed by conclusions based on the results. We should create an objective study to evaluate the potential for duplication of plucked hair grafts. How can we do this? It will not be easy and it may be nearly impossible to prove. There are many obstacles in the way to obtaining useful data. The greatest challenge will be to differentiate which of the more than 20,000 to 30,0000 follicles in a donor area might be the original plucked follicle. Finding a needle in a haystack might be easier simply because the needle looks different than the hay.

    A theory that predicts everything predicts nothing. There are infinite probabilities from plucking hairs so there are infinite potential outcomes. Dr. Cooley has stated that sometimes he plucks an intact follicle, but other times he plucks a nearly intact follicle. When an intact follicle is plucked, we can anticipate very little regrowth in the donor as my hair plucking efforts with FUE have demonstrated. When we pluck a nearly intact follicle, the total amount of residual tissue remaining in the donor area has infinite uncontrollable outcomes such that regrowth is unpredictable. In fact, Dr. Cooley has provided insight that nearly intact follicles from the beard and scalp may have a higher yield when treated with Acell. How much tissue remains in the donor area? Is there only outer root sheath and follicular sheath, or is there some inner root sheath and dermal papilla that remains? Does the amount of tissue and embryological origin have any affect on regrowth? Take for example Figure 1. The upper follicle is an intact follicle. The lower follicle is a plucked nearly intact follicle that lacks only a tiny fraction of the outer root sheath and dermal papilla. The residual fraction in the donor area is estimated by the orange. Suppose that only this tiny amount of tissue represented by the orange color remains in the donor area. What is the probability that his tiny fraction can produce a follicle that is an exact duplication of the original follicle especially without Acell treatment? We do know from transection studies that we often leave far more tissue in the donor area than is depicted by this orange fill, but we do not get 100% regrowth of transected follicles. When we leave 50% of the intact follicle in the donor area, we can expect no more than 50% of them to grow. With so little tissue remaining in the donor area following plucking, how can we imply that we are duplicating hair follicles?

    Simple answer :

    1) A plucked hair is plucked from its sourroundings (stem cells and everything else for regeneration is still there)

    2) FUE : Well here you stance out the WHOLE follicle as an Organ and also you cut out the sourroundings of the follicle as well

    So there is obviously a difference. In the first case you didnt detroy or take away the ability for regenerating a new follicle or to be more prcise to create new dead material (a visible hair). Its the same as what women do in general when they agressively wax their bikini zone or legs or whatever. The hair always comes back. The whole area where a follicle lives is filled with stem cells and the factors for regeneration. If you take away something from this it will regenerate as simple as that. Think of it as a family who lives in a house, where you take away a family member each time. The house can still be filled with people etc

    In the second case : You took away everything. Its like you would take away the whole house here and not its residents. So therefore the house is gone and also the ability to fill this house with people again.

    Also your statement doesnt make sense to me. If it would be like you said, how would it even possible for eye brows to grow again? I tweeze them very often and there is a huge amount of white tissue sourrounding it. How do you explain that.

    And then on the other hand you demand for a study? So why would you perform a study if you personally believe that plucked hairs dont grow? If you want docs to help you with this, then just ask them directly, i am sure they will gladly help you with the protocol etc.

    As some of them already said, they plucked a whole area and tattoed it and all the hair did grow back, i really dont know why you keep on argumenting about "If plcuked hairs do grow or not"? All people here male or female KNEW for good that plucked hairs grow because they almost do pluck hairs on a weekly routine.

    No there are not infinite outcomes of plucked hairs there are only a few

    1) Donor regeneration Yes or No
    2) Successful transplant in Recipient site Yes or No

    There is nothing in between which should interest people. Only because we cant explain why certain things work, it doesnt make them automatical "Not working"

    I Repeat FUE is not hair plucking. With Fue you extract the whole organ, and then its clear that nothing will ever grow there again. Plucking is just tweeze em out and thats it, but its not about extracting a WHOLE ORGAN.

    The tissue left in the donor side has its genetic SOP Modus, its called Survival and regeneration. I would say it otherwise, the Doc out there who is capable of stopping stem cells to regenerate follicles, should be considered for a nobel price because he had suppressed regenerative abilities, which at this point in time is IMPOSSIBLE. No one can stop cells from regenerating only by plucking hair. Nature had this already in mind that sometimes hars will be plucked, so its clearly obvious that they will gow back.

    Another example, if you would lose your nail (it has some characteristics like hair) why does the nail grow back after some time? If you get scared, why do the wounds heal amost scarless in minor injuries. How can the liver regenerat itself?

    If it would be like you said, i think we all should just shoot ourselfes because then our body wouldnt be capable of regenerating anything and therefore the whole mankind would be dead within the next 4 months.

    Also you are only making assumptions because you ask us how far the chances are that small tissue remakrs can form a new follicle.

    Ok then here is another one "How far are the chances of a small clump of cells to form " A Human"? Dont answer this, it was a rhetorical question.

    I am really diasgreeing with you and also get a little bit angry at this point, not because i desperately want plucking to work (almost anyone knows that it works) but more of this really sheer ignorance here and not listening to hairloss sufferers.

    Acell is no magic here, its just increasing or accelerating mother natures healing abilities and thats it no hocus pocus no nothing. And to give you another example.

    You yourself put your Grafts into a storage solution. Why do you do this? Correct to increase the odds of survival for the time out of the body. So and Acell when brought to the plucked sites is just working as an in vivo Cell Matrix or Accelerator thats all.

    And btw a lot of users here were willing to help you with this, like plucked hairs and Acell tests and also CIT Multiplication test, they send you emails etc but you never answered them, so if you really want to have a study going on then you should listen to what those people have to say and what they send you in emails.

    Hi Dr. Cole,

    I have a great respect for your expertise in hair restoration and really do appreciate your input on Acell and its possible applications in this field.

    I think it's best to take a cautios approach to any new, not fully tested, discovery in medicine. However, I think your comparison is unfair. You obviously has far more expertise in this field than I do, so maybe it's stupid of me saying this, but surely there is a demal papilla attached to the lower follicle? Does it really come from a plucked hair, or am I seeing things wrong? The picture you provided here, gives a whole other story of a plucked vs a dissected follicle: http://www.baldtruthtalk.com/attachm...1&d=1296839761

    I think the key is not how much that is left of the follicle, but rather how much of it that is removed. As long as even a small amount of the dermal sheath is left intact, additional MSCs will migrate to the area of wounding. Since the environment provided by what's left of the follicle is left unchanged, the follicle will be regenerated. However, if too much of the follicle is removed, there is the possibility of triggering a response of fibrosis and subsequently scar the follicle.

    Any news on seeing regrowth from your CIT procedure with the implementation of acell Dr. Cole?

    Anyone can get as upset about this all they want, but it is not going to change the facts.

    Let me quote Dr. Cooley from 2006.

    "March/April 2006, Volume 16, Number 2, p. 39 Co-Editor's Message Jerry E. Cooley, MD

    I was born and raised in Missouri, the "Show Me State." The origins of this nickname are obscure but the most common explanation is that it was coined, or at least popularized, in 1899 by a U.S. Congressman from Missouri named Willard Duncan Vandiver. Vandiver, a scholar, writer, and lecturer was speaking at a meeting in Philadelphia and was questioning the accuracy of an earlier speaker's remarks. Vandiver declared, "I come from a state that raises corn and cotton and ****leburs and frothy eloquence neither convinces nor satisfies me. I am from Missouri. You have got to show me." Missourians were known as nononsense country folk who demanded proof before accepting something as true.

    The "show me" attitude is not necessarily rude or confrontational. In our professional lives, we are frequently presented with claims about new techniques and the results certain surgeons are able to achieve. There is absolutely nothing wrong, and in fact it is our duty, to politely request proof for such claims. Some, however, seem confused about the distinction between "tell me" and "show me." Telling others about your new technique is the first step, but this should be followed by presenting credible evidence.

    When Dr. Gary Hitzig began claiming several years ago that he was "auto-cloning" beard hairs, I was naturally skeptical. So I flew up to New York and asked him to "show me." With a flick of his wrist, he plucked a bunch of beard whiskers from a patient using his special needle holder. When I looked at his grafts under the microscope, I was surprised to see that many (not all) were in fact intact hair follicles! I had truly been shown, and there was no doubt in my mind that intact beard follicles could be plucked and transplanted to the scalp where they would grow. Textbooks typically describe plucked scalp hair as having only some adherent epithelial cells from the outer root sheath. To my knowledge, there has never been reports of being able to pluck intact follicles. Time to revise the textbooks!

    The concept of donor dominance has been a well-accepted principle in our specialty for 50 years. Along comes Dr. Tommy Hwang who claimed that the recipient site had an important influence on grafted hair. His initial results were published in a peer-reviewed medical journal, and in this issue he shares his long-term results. He provides compelling proof that the recipient site determines graft survival and subsequent growth rate while hair caliber remains similar to hair from the donor site. In my mind, he has convinced me that our new understanding should be of "donor dominance/recipient site influence." Now we need research to understand exactly how the recipient site affects graft survival and growth rate. Is it merely a function of blood flow? Some of those doing body hair transplants have claimed that chest hair grafted to the scalp will grow longer like scalp hair, but we need more convincing evidence of this. It would certainly add more support to this emerging concept.
    Jerry Cooley, MD"

    Now the fact that he is describing this whole situation differently 3 to 4 years later does not change the facts. A standard plucked hair contains very little tissue as Dr. Cooley noted back in 2006. it will grow back. What Dr. Cooley and Dr. Hitzig are doing today is plucking mostly intact follicles or intact follicles (the WHOLE ORGAN as you put it).

    If they apply acell to the plucked area, they might see more regrowth. i still don't know how you study it because there is no way to determine if the hair you plucked is the same follicle that grows on the top and the donor area because all follicles look the same. With body hair, you can totally remove an area through FUE and then go back 6 months later and it is full of hair. it is thinner, but there is plenty of hair. The reason is that there are many hair in the exogen phase on the body.

    I've seen up to 54% regrowth in my FUE extraction sites by putting Acell in them. Yes, I am essentially plucking intact follicles and i'm getting regrowth. This is why i suggest that Dr. C and Dr. H apply acell to their donor area where they pluck hair. I still want to know what the yield is with these plucked hairs and what the hair diameters are. If the yield of plucked hair is lower than with transplantation, then i would say in general that plucking is not an efficient means of restoring one's hair.

    Dr. Cole,
    Very interesting posts. Just one question, when you say you have seen up to 54% regrowth it means not all of your patients have had these results. What would you say is the average amount of regrowth on patients treated with ACell in their donnor areas? Also, are you expecting these numbers to go up anytime soon?
