Article – Fiery Redheads Have More Sex

This article was published last August, but somehow I guess I missed this. Thanks to the two readers that brought this to my attention recently.

From the article —
The study by Hamburg Sex Researcher Professor Dr Werner Habermehl looked at the sex lives of hundreds of German women and compared them with their hair colour.

He said: “The sex lives of women with red hair were clearly more active than those with other hair colour, with more partners and having sex more often than the average. The research shows that the fiery redhead certainly lives up to her reputation.”

Article: Two articles on microneedling

This article requires a lot of patient feedback which can be quite subjective; nevertheless, the focus of the article is interesting and I suspect would be as good with finasteride as with dutasteride.

Topical dutasteride with microneedling in treatment of male androgenetic alopecia

Introduction Male androgenetic alopecia (AGA) is the most common type of hair loss in men. It accounts for more than 90% of all cases of alopecia in men . It occurs when genetically predisposed men are exposed to androgens. AGA may negatively affect patient’s quality of life and can lead to social and job-related problems . AGA can also cause indirect physical harm, such as sunburn as a result of hair loss and exposure to ultraviolet light . AGA may also be associated with increased incidence of hypertension, hypercholesterolemia, and myocardial infarction . The only FDA approved therapies for treatment are limited to topical minoxidil and oral FIN with limited efficacy (40-60%) . As multiple factors are implicated in the pathogenesis of AGA and the existing conventional therapies (i.e. FIN and minoxidil) fail to target all of them; the demand for new treatment techniques for AGA is growing . Dutasteride (DST) is a dual 5?reductase inhibitor, with some reports about the use of oral DST in the treatment of AGA in men . Hesitancy about the widespread use of oral DST in the treatment of male AGA results from its potential side effects on erectile, ejaculatory functions and fertility . Mesotherapy using DST has been used in patients with AGA with promising results (8, . It is believed that systemic absorption after mesotherapy is equal to after oral DST because the scalp is highly vascular. So the possibility of using DST topically with scalp MN would have some advantages . Microneedling (MN) is a relatively new minimally invasive procedure involving superficial and controlled puncturing of the skin by rolling with miniature fine needles . The use of MN in combination with minoxidil showed promising results in treatment of AGA . Furthermore; the addition of MN to minoxidil and oral FIN improved AGA in patients who were resistant to minoxidil and oral FIN . To the best of our knowledge; the use of MN in combination with DST hasn`t been previously reported. This study was designed to evaluate the efficacy and safety of topical DST with MN in treatment of male AGA. Patients and methods This prospective, randomized, clinical study was approved by Ethical and Research committees at Faculty of Medicine, Sohag University. An informed written consent was obtained from all participants. The study included 30 male patients complaining of progressive hair loss diagnosed as AGA attending at Dermatology outpatient clinics at Sohag University Hospitals, Faculty of Medicine, Sohag University. Exclusion criteria ? Patients with other forms of alopecia including telogen effluvium, alopecia areata. ? Patients with dermatological or systemic illness known to cause diffuse hair loss (as thyroid disorders or anemia).

As hairs grow longer, they lose their thickness

The first picture is from Dr. Robert Haber’s magnified study of a hair scan of a single hair on one of Dr. Paul Cotterill’s female patients. It revealed that hair thickness and shape changes as the hair grows longer. The measurement scan below demonstrates the changes in this 21 cm long female single hair. Telogen is on the left (the end of the hair cycle) and the start of anagen on the right (where the new hair started to grow out from the scalp) showing how the shaft thickness and bulk builds as the hair starts growing and is widest at about 14-15 cm (about 15 months into the growth of the hair). It is clear that the hair thickness is greatest at the 14 -15 cm. length of the hair in this female patient. Dr. Haber told me that this was a normal female hair and she had no symptoms of a hair disorder. Clearly we need to understand the various conditions that this technology is capable of showing us as hairs are evaluated with regard to many different treatments.

In the second chart, a hair shaft thickness is shown over its length and the researchers, Dr. Michael Rabin and Dr. Robert Haber show the impact of an event that occurred in this particular patient’s hair (which had grown out for 22 months) but the event occurred 16 months into its growth cycle. The large arrow shows pointing down shows the timing of the event and it this case it was a PRP treatment 6 months ‘in time’ prior to the hair being cut off at its base at 22 months growth. Note this hair’s emergence from the scalp (beginning of anagen on the right) and the point where PRP was administered 16 months into its growth cycle (shown with large red arrow pointing down). It is easy to see the point where the event occurred, but interpreting it is another story. Is this a good result or a bad one? Was the hair ‘healthier’ after the PRP injection. The graph suggests it was less thick, but maybe it was a healthier hair?

This is exciting research to me because now after seeing it, I would want to know the impact of drugs like minoxidil on a normal terminal hair, (we now believe that there is no impact), the impact of finasteride on a miniaturizing hair (we now believe it increases the hair shaft thickness) and the growth of a single long hair with the patient on finasteride over time (does the benefit build slowly or is it a one time hit?). I just loved the creativity of these clinical researchers in producing a tool that can expand our knowledge in what is still, at times, a ‘Black Art’ for, the treatment of hair loss. .

Artificial Hair

I understand that there is something out there called artificial hair. Where can I get it and how does it work?

Artificial hair is a product sold in Asia and limited countries in the western world. It has been banned by most countries because it must be surgically implanted with a special sewing needle. This would be a procedure that would need FDA approval and it has not been approved as safe in the United States. Many patients’ bodies will actually reject the artifical hair as it would any foreign body once it is implanted into the scalp. I have seen some patients with wonderful results. It gives ‘instant hair’ and as a result it is a big selling point in countries where it is allowed, BUT I have also seen patients that have developed massive scalp infections from these ‘artificial hairs’. There is a trade off and safety is sacrificed in exchange for short term benefits. Biofibre is one of the sites for artificial hair. Reading it might give you more information, but I would strongly caution your pursuit of this as a solution for your hair loss.

Artificial hair does not need to be included in any hair cut and you can not grow your hair out with them as you could with hair transplants. Hair transplants allow you to grow your own, natural hair for as long as you live.

Artificial Hair Implanted with Lasers?

Dear Doctor.

I lost 50% of my hair and I found in Lebanon a place called Advanced Hair Studio Center. They make fiber hair and stick it by using Laser. As I know before this is banned in Europe, did you have any advice for me to do it? If yes please advise me if 3000 pcs is enough to cover 40 square centimeter?

If the fibers are being put into the skin, you will almost certainly run into rejection and infection issues. Artificial hair is dangerous and banned in most countries.
