The cause of female-pattern hair loss is unknown, but doctors said there is a strong genetic component. The risk can come from male or female relatives. Though it looks as if the hair is falling out, that's not really what's happening. Cotsarelis said hair follicles are becoming smaller and producing hairs that may be so small that you can't see them. Women tend to retain more normal, thick hairs than balding men do.
Involutional alopecia. This one is less of a medical condition (it's not caused by a disease or genetics) and is more concerned with the hair growth cycle. Also called telogen effluvium, this condition is marked by a long dormant phase of telogen than growth or anagen. This type of hair loss is the second most common next to pattern baldness but is also the most unpredictable and difficult to pinpoint its cause. Studies have shown that the dormancy phase in the hair growth cycle is related to a range of factors, including hormonal imbalances, pregnancy in women, stress, diet, etc.
Researchers from UCLA in the lab of Jing Huang have recently shown that certain molecules which activate the cellular process known as autophagy also drive hair follicles into the anagen (growth) phase. The researchers studied different metabolite molecules and other molecules which are FDA approved and on the market as drugs. The most recognizable drugs from the study were metformin and rapamycin, one is a diabetes medicine and the other an immunosuppressant. Dr. Huang says her lab is looking to study these drugs for human hair growth soon. In my opinion, results from that study are something to look out for. Full article on the Articles page.
In-office laser light treatments or at-home handheld devices, such as the HairMax LaserComb, supposedly grow new hair by stimulating blood flow to the area (think: an amped-up version of a scalp-stimulating shampoo). Just don’t expect the device to make your noggin go from looking like George Costanza’s to Jerry Seinfeld’s. “These lasers won’t grow any new hair. If anything, they may just help you hang on to some of the hair that you already have a bit longer,” says Dr. Joyce.
Scientists from the Indiana University School of Medicine have for the first time created skin with hair follicles using mice stem cells. Research was led by Professor Karl Koehler. The team was able to grow both the epidermis and dermis layers of skin to create a realistic skin model. An interesting quote from Professor Koehler: “It looks like a little ball of pocket lint that floats around in the culture medium. The skin develops as a spherical cyst and then the hair follicles grow outward in all directions – like dandelion seeds.”
