1960's - Large plug technique

The first document about hair transplantation was publicized in the United States. The document described how small circle like skin grafts (tissue that contains multiple hair follicles) could be successfully transplanted from a healthy donor area to a bald or balding area. The instruments (punches) used to remove the grafts where about 5 mm in diameter and contained 10 to 20 hair follicles. These plugs where associated with the first hair transplants. The hairs from these plugs did grow, but the effect was far from natural looking and could be recognized by anyone. Only very few institutes still use this technique to date.
 

1970's - Larger sessions 

Improvements in the development of surgical instruments led to the usage of smaller punches, 2-4 mm in diameter. This allowed for larger sessions and smaller grafts in a single session. Although more hair could be transplanted with smaller units the resulting hairline was not undetectable.
 

1980's- Minigrafts and Micrografts

During the 1980s, minigrafts (smaller clumps containing 5-8 hairs) were an improvement, but only served to generate smaller "plugs". Indeed, many hair restoration procedures involve the repair and/or hairline camouflage of these "plugs" or "minigrafts". Even more unfortunately, some hair transplant doctors still utilize these larger grafts. As techniques have improved, the grafts have become smaller and the number transplanted per session has increased. Today most hair transplant surgeons use grafts that have from one to eight hairs, with 200 to 800 grafts transplanted in each session. Although this is a major improvement over the larger grafts, this procedure still can produce a slightly unnatural look.
 

1990'a - Follicular unit micrografting . 

The next evolution in surgical hair restoration techniques is called follicle-unit micrografting, and it has revolutionized the approach to many forms of hair loss. With this method, many hundreds or thousands of tiny, living grafts containing only one, two, three or four hairs are inserted in closely spaced fashion over the entirety of the bald and thinning areas. These follicle-unit micrografts, which approximate the one to four hairs which naturally originate from each of your original follicles, result in a very natural, aesthetic appearance. Randomly-spaced single hair micrografts are used in the very front of the hairline to create an especially pleasing, feathered hairline. To date most institutes still practice this method which is better known as 'strip' surgery or FUT.
 

From 2004: Prohairclinic-First and only FUE clinic in Europe

In 2004 the first European FUE hair clinic was a fact. Prohairclinic performs daily FUE hair transplantations. The team is virtually unchanged to this date. That is perhaps why Team Prohair is one of the most experienced teams worldwide. 

Present - The FUE method has become the choice of the patients

Whereas older technique where very invasive, requiring the removal are large pieces of tissue, the newer FUE method can be performed without the use of scalpel or sutures. FUE only uses follicular units as a source for transplantation, resulting in an undetectable hair transplant. The recovery time after the operation has been reduced to a few days, instead of weeks or months with the older methods. FUE surgery virtually eliminates complications like painfull and large scars that are associated with strip surgery. That is why most patients today prefer a non invasive type of hair restoration. Since 2007 Prohairclinic is capable to conduct Mega sessions.
