There’s been a revolution in biology.
They’re coming, promises George Cotsarelis, MD, director of the Hair and Scalp Clinic at the University of Pennsylvania. Armed with powerful new tools, scientists are learning how to read the complex chemical languages of the body, including how to coin new treatments for hair loss. Those new treatments aren’t nearly ready for prime time, like the cure for cancer.
Hair follicles live just below the top layer of the skin. You have them all over your body except, fortunately, on your lips, palms, and soles. Certainly, the other half becomes a completely new stem cell, and stays put for future regeneration. Anyways, that’s where follicle stem cells live. Now let me tell you something. They don’t divide like normal cells, in which both halves become new cells that split and developing. These self renewing cells divide, when they get the right set of chemical signals. As a result, only one the follicle half stem cell does that.
a number of us, when we think of hair loss, think about aging men.
Nearly all men eventually get that receding M shaped hairline and thinning hair on the top of the head, on top of this known as male pattern baldness. However, aging women have a similar problem. It’s a well it’s called androgenetic alopecia, and it’s caused by a ‘by product’ of testosterone called DHT. Furthermore, although it’s not clear that’s necessarily caused by sex hormones, their hair gets thin.
What’s clear is that quite similar thing happens in aging men and women. Result. On top of this, the follicles on the sides and back of the head aren’t affected by DHT and usually stay healthy. Thin, very short hairs and many follicles empty of hair shafts. Therefore the anagen stage of hair growth gets shorter, and the resting stage gets longer. Hair follicles get smaller. Oftentimes that’s where hormonesensitive follicles live. Why is this pattern of hair loss only in the front and on top, am I correct?
Alopcia areata ain’t associated with a more serious condition known as cicatricial alopecia, in which the overall health attacks the stem cells in the bulge of the folicle.
This results in permanent hair loss. Oftentimes minoxidil originally developed as Rogaine fights androgenic alopecia in both men and women. By now, a lot of people know that men can buy shampoo with an ingredient called minoxidil.
It’s still not entirely clear how minoxidil works. It keeps the male sex hormone testosterone from forming its DHT by product. And now here is the question. Why? There’s disagreement about how well it works.
DHT signals shorten the growth phase and lengthen the rest stage of hormonesensitive follicles. Other currently approved drug for hair loss is Propecia. Despite experts disagree about how much, it also promotes new hair growth. Of course used properly twice a day, massaged deep into the scalp it slows new hair loss. Known it works only for men.
One aftereffects of Propecia can be loss of libido.
It usually goes away over time, Cotsarelis says. Notice, today’s hair grafts are called follicular unit hair transplants of one to four hairs, transplanted very close together for a more natural look.
Similarly out of fashion are flaptype procedures, where a flap of hair from a ‘hair bearing’ area is partially removed, swung around, and attached to a frontal area. Basically the Holy Grail of hair loss treatment is getting shutdown follicles to regenerate. That’s what Cotsarelis’s lab is working on. With that said, this can lead to scarring or death or a portion of the scalp. They’ve learned how to manipulate these stem cells in the test tube. Of course already they’ve made a major breakthrough.
It’s, if this all sounds futuristic.
Similarly out of fashion are flaptype procedures, where a flap of hair from a ‘hair bearing’ area is partially removed, swung around, and attached to a frontal area. There’re good reasons this kind of technology will move forward. Seriously. Today, Americans spend million on hair restoration surgery. Now let me tell you something. Actually the other half becomes a totally new stem cell, and stays put for future regeneration. They don’t divide like normal cells, in which both halves become new cells that split and developing. These self renewing cells divide, when they get the right set of chemical signals. Only one the follicle half stem cell does that. Then again, that’s where follicle stem cells live.

Then the experience of hair loss is still stressful and frustrating for most people, while losing a little off the top was not the social exile that it once was.
About 70 men percent and 40 percent of women go through some degree of hair thinning as they age, almost usually for a reason of androgenic alopecia, otherwise known as male or female pattern baldness.
Is this cure actually even possible, is that the case? Finasteride and Minoxidil are very safe medications that significantly boost and even regenerate our noggin’s capacity for hair growth. Therefore, if so, just how far from it are we, this is the case right? It’s a well though heaps of products and treatments currently exist to fight back against hair loss, a notorious permanentcurewould probably be amid the most exciting scientific discoveries to come alongin a long time, right behind fat free bacon and unlosable house keys. By conventional standards, the current line of hair loss treatments are pretty damn effective, though ultimately limited in their capabilities.
For the short primer. Cycle can be interrupted or made shorter by plenty of things, including when blood levels of the androgen Dihydrotestosterone are like with AGA, or when the health is mistakenly compelled to attack the follicle, like with alopecia areata. Did you know that the follicle so undergoes a short hibernation phase of about three months, recuperates, and sheds the current hair strand attached to it before starting production back up. Usually, it can also be permanently shut down when folliclesare damaged beyond repair. You see, at any one time, about 10 our follicles percent are in that resting state while the rest are happily pumping out luscious tubes of keratin. That’s right! Hair continuously grows out of a single follicle for a period of about four years, all the while being nourished by surrounding cells.
