Evaluation of the hair growth and retention activity of two solutions on human hair explants Independent Laboratory Evaluation and Experimental Report Hair loss is often caused by abnormal hair fol icle cycling and changes in hair fol icle morphology. The molecules and biochemical pathways that control normal hair fol icle formation, hair growth, and hair loss are beginning to be understood. Despite advances in hair research, current treatments on the market such as minoxidil and finasteride have limitations. Both solutions work very slowly, and finasteride particularly has some negative side effects therefore patient compliance for these treatments is low. An alternative or complementary treatment to topical minoxidil solution is highly desirable. Vascular Endothelial Growth Factor (VEGF), a cytokine natural y produced in the body has been characterised and identified as a key mediator of hair growth. With the aid of recombinant DNA technology, safe, identical copies of VEGF protein can be biosynthesised and used in treatments. The objective of this study was to assess and evaluate the efficacy of Nanogen VEGF, or "Hair Growth Factor" and 5% minoxidil solution alone and in combination with each other. An ex vivo experimental model utilising human hair was designed to compare the effects of these two treatments. Nanogen Hair Growth Factor outperformed minoxidil by as much as 237% and showed a complementary effect on minoxidil treatment when used in combination. Al results were statistical y significant. In the field of hair research, VEGF (Vascular Endothelial Growth Factor) has been identified as a key mediator of Throughout the history of medicine, a tremendous hair growth (Figure 1).

They can control al aspects of cel ular proliferation and differentiation. Tissues in the body communicate constantly through a flurry of these signals. Their existence is not a surprise to the scientific community, however the intensity and breadth of their effects was not ful y understood and appreciated until now. The effect of cytokines or "growth factors" as they are commonly known is so significant that they would have great utility if they could be characterised, isolated Figure 1 Tertiary structure (3D) of Vascular Endothelial and applied correctly as therapeutic agents. 2012 Copyright Nanogen Hair Research.

Evaluation of the hair growth and retention activity of two solutions on human hair explants Independent Laboratory Evaluation and Experimental Report Experimental Design & Methods To test these hypotheses, an experiment was designed A scalp plasty from a human donor was micro-dissected to compare the effects of Nanogen VEGF with 5% to isolated 80 individual hairs and their bulbs. Each hair minoxidil, via an ex vivo experimental model utilising was cut approximately 1mm above the infundibulum. human hair. The objectives of this study were to (Figure 2.1, 2.2). measure and compare: Hair growth rates after topical application of Nanogen Hair Growth Factors and minoxidil. Hair fol icle survival after topical application of Nanogen Hair Growth Factors and minoxidil. The effects of combination therapy with Nanogen Hair Growth Factors and minoxidil. Bio-EC - an independent clinical testing laboratory based in France, was instructed to conduct a study investigating Nanogen Hair Growth Factors, using minoxidil as a positive control. The study utilised Figure 2.2 Micro-dissection of a hair plasty. impartial measuring techniques, and was blind as the containers of growth factor and minoxidil were label ed anonymously.

Evaluation of the hair growth and retention activity of two solutions on human hair explants Independent Laboratory Evaluation and Experimental Report The hairs were then placed in 48-wel plates and kept in classical survival cel culture conditions (Philpott medium, at 37°C in a 5% CO2 atmosphere). The hairs were re-measured on day -4 (4 days post micro-dissection). Those demonstrating a healthy total growth of 54 to 1641 µm were selected, randomised and distributed into different batches of 7 hairs for product testing.

The complementary effect of Nanogen Hair Growth Factors on minoxidil treatment When compared to minoxidil, Nanogen Hair Growth is clearly evident. However, the combination did not Factors are significantly more effective at stimulating hair increase survival as expected. There is no theoretical growth. Up to 237% faster growth rate was shown basis for the two treatments to interact; therefore this in the growth factor group compared to the minoxidil may be due to the smal er sample number in the second positive control (Figure 3.1). A Student's t-test test, or perhaps the increased dilution of Philpott found a statistical y significant difference between the medium caused by adding both treatment solutions. At the end of the hair cycle, as before hair fal s out, necrosis (death) of some cel s in the bulb region can occur. This is responsible for the smal reduction in hair length. Treatment with Nanogen Hair Growth Factors al owed the hairs to continue growing at a healthy rate. In contrast, with minoxidil monotherapy, hair length begins to decline from day 9, indicating necrosis prior to the onset of hair loss. This shows that Nanogen Hair Growth Factors prolonged hair survival more effectively than minoxidil. Figure 3.2 Graph to compare average hair growth rate over time in minoxidil against a combination of minoxidil and Nanogen Hair Growth Factor. It can be concluded that: Nanogen Hair Growth Factor treatment can significantly increase hair growth rate, up to 237% more than minoxidil monotherapy. Figure 3.1 Graph to compare average hair growth rate Nanogen Hair Growth Factor treatment over time in minoxidil against Nanogen Hair Growth prolongs hair survival, and therefore can prevent or reduce hair loss. After these results, the test was repeated to investigate the combination of Nanogen Hair Growth Factors with Nanogen Hair Growth Factors in combination with minoxidil can significantly increase hair minoxidil, in comparison to minoxidil alone. 133% higher growth rate by up to 133% more than minoxidil hair growth rate was observed with the combination treatment than with minoxidil treatment alone (Figure 3.2).
