When to take bodybuilding supplements based on protein (07/14/2011)
(...) Obviously, the simplest way to buy such kind of supplement would be to ask one’s fitness trainer or even the frequented gym’s staff. Bodybuilding supplements are marketed and sold to customers with no dependence on a prescription, therefore sport nutrition sales have risen to staggering heights, causeing this to be one of the most profitable industries of the modern world.
Bodybuilders don’t necessarily need to eat protein. (...)

Wearing Hats Causes Hair Loss
More than a few people believe that hats are to blame for baldness based on the idea that hats cut off air circulation to the scalp and prevent the scalp from breathing. What they don’t know is that hair follicles get oxygen from the bloodstream, not the air, so you can’t suffocate your hair follicles just by wearing a hat. The baseball cap so often worn by men whose hair is thinning doesn’t cause baldness it hides baldness. (...)
Follicular unit extraction allows the surgeon to remove individual follicular units (06/19/2010)
(...) FUE has the following advantages:
There’s no linear scar in the donor area. Of course a scar always results from every skin incision, but since scars are very small and scattered in a larger area, they often aren’t detectable even when the hair is relatively short.
There are no sutures or staples to be removed. (...)
Single strip harvesting removes the donor tissue as a single strip (06/19/2010)
(...)
The FUE technique can also produce superior hair yields, especially with new technology just being developed. The problem with FUE is that it is very taxing on the surgeon doing the procedure and requires intense concentration for prolonged periods of time to perform the surgery. The surgeon’s fatigue becomes a factor when this technique is extended to more than 1000 grafts. (...)
Follicular unit transplantation (06/19/2010)
(...) Applying this technique to FUT, all the follicular units are removed from the donor tissue under microscopic control to avoid damage.
Complete stereo-microscopic dissection increases the yield of the number of follicular units as well as the total amount of hair (upwards of 25 percent). The hair seems to come out of a single hole and that the hairs are bundled together in their naturally growing groups. (...)
Minigrafts and micrografts consist of multiple follicular units (06/19/2010)
(...)
Micrografts tend to have more skin in the graft, which makes them lose their skin pigment. Even micrografts containing as few as two or three hairs may contain the skin between two follicular units, which is unnecessary.
Micrografts look thin when used exclusively over the entire head and may produce inconsistent graft growth. (...)
Small versus large hair grafts (06/19/2010)
(...) Until these new blood vessels grow into the graft, the graft’s cells depend upon the surrounding tissue to bring the needed oxygen and nutrients for their survival.
Hair follicle cells have a very high metabolic rate, and they require more oxygen and nutrients than other cells. If the graft is too large, the cells of the follicles in the center of the graft may die before sufficient oxygen and nutrients can reach the center of the graft. (...)
Avoiding the hair transplant look (06/19/2010)
(...)
As the skin of the graft heals, the melanocytes (the part of the skin that produces pigment) may not recover from the transplant process and give the graft a whitish appearance. This is particularly a problem for anyone with a dark skin color.
Hair in its natural state is composed of hair groupings of follicular units that have one to four hairs close together. (...)
A hair transplant that relied entirely on the use of micrografts (06/19/2010)
(...) In refining the technique, doctors came to understand that moving more hair in the transplant would eventually lead to fuller and better aesthetic results. The technique defined by Dr. Uebel evolved into what’s now called the megasession, large session transplant surgeries. (...)
Scalp reduction techniques (06/19/2010)
(...)
There was a distinct change from the hairless forehead to a heavy line of thick hair and then, if the patient had any degree of baldness behind the flap the ‘island’ of flap would be easily seen.
Unlike a natural hairline, which has a slow transition from the bald forehead to the thicker hair area behind it, the flap had a detectably abrupt hairline and then an abnormal transition to baldness on the back side of the scalp.
One flap couldn’t cover the entire reconstructed frontal hairline, so two flaps were often used and joined in the middle or off to one side. (...)
Tracing the evolution of hair restoration techniques (06/19/2010)
(...) In fact, the same size punch used to remove tissue from the back of the scalp was also used to remove bald skin from the front. It was replaced with hair-bearing circles of skin from the back and sides of the head where the hair was permanent.
This punch graft technique was the standard procedure for all hair transplants for many years. (...)
Hair Restoration Options: Past and Present (06/19/2010)
(...) He investigated the concept of auto transplantation (transplanting from one part of the body to another) using hair, feathers, and skin in animals.
Although there were sporadic reports of hair transplantation in European and Japanese literature during the mid to late 19th century, the modern era of hair transplantation really began in 1939 with the Japanese dermatologist, Dr. Okuda, who used small grafts to correct various hair loss conditions of the scalp, eyebrows, and mustache.
