Invention - A Patent Hand-held Laser Device for Halrline Placement
Stimulated by Shiao's work, we have been working on a portable laser device that can overcome the above limitations. The first prototype was built in March 2008 and we found it helpful in rapid hairline placement. The device made its first appearance at the ISHRS Asian Workshop in Korea in 2008. It was later presented in the 2009 ISHRS Annual Scientific Meeting in Amsterdam.
Our Patent Laser Device consists of a class IIIA horizontal beam laser module (3 volt, maximum power 5mW, 650nm wavelength) wired to a battery box. The current model is the 5th generation. In order to overcome the previous problem of unsteadiness and tilting, we mounted the laser on one end of a 15 cm supporting frame. This new design also makes it unnecessary to maintain the patient in a rigid sitting position. Read More »
Research 1 - Stem Cell Therapy in Treating Hair Loss
Stem cells have the potential to turn into a wide variety of body cells. We believed that the activation component of the supplied kit failed to trigger the differentiation of SVF into the desired hair follicle tissue. The company is in the process of refining the kit before the study is repeated. The result of this study was

- Presented in the 2009 ISHRS Annual Scientific Meeting in Amsterdam, Netherland
- As reference for the latest Unger 5th Edition "Hair Transplantation" Read More »

Research 2 - Vitiligo - Repigmentation by Follicular Unit Grafting
Single hair grafting can be considered in the treatment of localized and segmental vitiligo in the exposed areas. This case study suggested that the different melanocytes carried by the hair follicle have different immunological response to vitiligo. Grafting should include the middle one-third of the hair follicle which contains the maximum amount of Outer Root Sheath Melanocytes.
The procedure is simple according to today standard and can be performed in any hair surgeon’s office.
Result of this study was published in Hair Transplant Forum International ( Vol 20:2, Mar / Apr 2010 ) Read More »

Research 3 - Hair Loss in the Donor Area After Hair Transplant
When patients come for hair restoration surgery, the last thing they want is to lose more hair. Yet this can occur in the donor areas after procedure.
There was confusions regaing the etiology of such hair loss. Drs Marzola and Vogel described the effluvium as anagen. We conducted a study to relate the hair loss to the hair cycle. We found that the majority ( about 75% ) claimed that hair loss started at 3-5 weeks. The others did not notice hair loss until 7-9 weeks. No case was reported after 9 weeks. The most common pattern was hair loss all along and on both sides of the wound.
Our result renders it possible in predicting the course of this distressing complication.The result of this study was presented in the 2008 ISHRS Annual Scientific Meeting in Montreal, Canada. It was subsequently published in International Forum ( March/April 2009 Volume 19, No. 2 ). Read More »
Research 4 - The Principles in Hairline Design
Da Vinci's Golden Rule of Thirds is widely used in western civilization to define the proportion of beauty. It has also been applied to hairline design, stating that an ideal face should have equal vertical distance from :
- Lowest point of hairline to Glabella
- Glabella to base of nose
- Base of nose to tip of chin
However as seen from the above pictures, this rule cannot applied to all individuals. Some happen to have a smaller or longer chins. The level of the hairlines have to be adjusted accordingly.
After analysising the facial proportion of hundreds of celebrities, we have found a new formula to locate the hairline.
The result was presented in the 2009 ISHRS Annual Scientific Meeting in Amsterdam, Netherland.
The presentation was reported as one of the "Finest" in the meeting.
We are using these formula in our daily work, and found very pleasing results. Read More »
Research 5 - Is it Safe to Keep Grafts in the Refrigerator
So far the optimal temperature for graft storage had not been determined. Very often Dr Limber’s study was quoted - that grafts immersed in chilled saline at 4 0°C have a survival of 88% even after 8 hours. For years chilled saline has become the Gold Standard.
This is a very common practice to put grafts in saline and then keep in the refigerator. It is based on the assumptions that this will somehow keep the graft at 4°C. However Dr Pathomvanich reported an incidence when all the grafts were frozen and then no growth. So how can we be so certain that this is a safe practice? Subzero freezing can cause intracellular crystallization. Can we risk any damage to the hair follicles by relying on just assumptions?
 
We have conducted a study in 2009 -2010 to compare the different methods in graft storage, and to evaluate whether it is safe to Keep Grafts in the Refrigerator. The result was presented in the 2009 ISHRS Annual Scientific Meeting in Boston, USA.
We showed that saline stored over a Blue Ice coolant is effective in reducing oxygen consumption up to 6 hours. Keeping the saline in the refigerator is a good alternative but one must be careful about the setting as there is a risk of drop the temperature to below 0 °C. Also the other possible risks have to be considered. Read More »
