Introduction to Nanoguard B active

Before you can understand how Nanoguard-B works, it is important to know about the hair follicle's life cycle. Each hair goes through this cycle independently of all other hairs on the scalp:

In addition to a twice-weekly shampoo Nanoguard A, which has patented anti-DHT properties, new Nanoguard-B is a once-daily aqueous solution applied directly to the scalp with three additional properties clinically proven to increase hair density and reduce hairloss:

There are a lot of graphs. What do I need to know?

In order to develop Nanoguard B as a final product, it was essential to test and demonstrate all of the effects as shown in the flow chart individually and at various concentrations. These results are summarised below. The text and results at the bottom of the page refer to the final product, containing 10% Nanoguard B active.

Regulates the hormonal balance

Hair follicles in the cases of androgenetic alopecia show an abnormally high level of DHT, an androgen converted from testosterone by the enzyme 5a-reductase. By inhibiting 5a-reductase activity, Nanoguard b severely limits the transformation of T into DHT, thereby limiting the cause of androgenetic alopecia.

Nanoguard B active tested at 0.25% on human fibroblasts shows a significant inhibiting effect on 5 Alpha-reductase II activity (-18%). This effect is comparable with a reference compound, finasteride. By inhibiting the activity of this enzyme, the Nanoguard B active limits the transformation of testosterone in 5 Alpha-DHT which is responsible for the follicles miniaturization characteristic of androgenetic alopecia.

Improves vascularization of the hair follicle

Formation of the vascular system near the follicle is an important and necessary factor in the development of hair. VEGF (vascular-endothelial growth factor) is one essential growth factor & has been shown to stimulate both neovascularization, also known as angiogenesis (new blood vessel growth) and vascular permeability (the capacity of a blood vessel wall to pass through small molecules, like water or nutrients).

Nanoguard B increases VEGF by over 30%, as well as making the existing vascular system around the hair follicle denser, which is necessary to provide follicles in the Anagen phase with the nutrients required for hair growth.

Nanoguard B active tested at 0.25%, 0.5% and 1% increases formation of vessels from the existing system. Nanoguard B active favours angiogenesis and thus facilitates the supply of oxygen and nutrients that are essential for cells during the anagen phase, during which cellular activity is very intense.

Stimulates cell metabolism

Cells in the Anagen phase are dividing continuously to support the formation and growth of hair. Therefore the metabolic activity of the cells around the hair follicle needs to be at a maximum for the formation of healthy hair growth. Nanoguard b provides zinc, iron and growth peptides to stimulate and boost metabolic activity in the hair bulb cells, favouring the growth of hair.

Nanoguard active (1%) favours the expression of mRNA coding for type 1 transglutaminase, a marker of keratinocyte differentiation. By boosting the metabolic activity of cells, an important process in the anagen phase, Nanoguard B stimulates hair growth.

The Nanoguard B final product

Above, you have just read about the individual effects of the clinically-proven Nanoguard B active on attenuating hairloss and promoting growth as tested in vitro at various concentrations.

Now, we are looking at the finished Nanoguard B product at 10% concentration tested on 16 real human volunteers suffering from hairloss.

The test
16 healthy male volunteers aged between 18 & 65, all with slight to moderate thinning hair. No volunteer had used an anti-hairloss treatment before. Nanoguard B was applied once daily for 12 weeks.

The evaluation method
A phototrichogram (standardised macrophotographic method) was judged at the start of the study, 6 weeks later and finally after 12 weeks.

This enabled the following to be judged:

• Hair density
• The number of hairs in the anagen phase (growing)
• The number of hairs in the telogen phase (falling out)

This test also enabled the Anagen/Telogen Ratio (A/T) to be calculated. When hairloss occurs, the number of telogen hairs increases, therefore decreasing the A/T ratio.

In a normal scalp, this ratio is between 4:1 (80%) and 9:1 (90%). When less than 1.5:1 (60%), the scalp is clearly pathologic.

Hair Density

The expected hair density in a scalp free of alopecia is in the order of 200-400 hairs per square centimetre. In people with alopecia, that density decreases considerably, especially in the crown region and may reach 80 hairs/cm²

Why does the total number decrease after 44 days?

When hair growth is stimulated, a large amount of follicles move from the Telogen phase to the Anagen phase simultaneously, which has the obvious consequence of hairloss during the initial phase of treatment (shedding).

Although it may sound counter-intuitive, more than usual hairloss is usually an indication the formula is working according to the published studies. The new hair that replaces that just lost will be thicker, stronger and with more colour.

Evaluation of Acceptability

At each visit, a dermatology examination was conducted on the scalp, with a search for the following signs:

• pruritus (absent, minor, moderate, major)
• seborrhea of the scalp (absent, minor, moderate, major)
• erythema (absent, minor, moderate, major)
• dandruff (absent, minor, moderate, major)
• exudation (absent, minor, moderate, major)

Evaluation of the effect of Nanoguard B on reducing hairloss

After 44 days of daily application of the product Nanoguard B

• Total hair density decreased slightly
• The density of hair in the anagen phase remained stable
• The Anagen/Telogen ratio increased considerably (+85.8%), resulting from a decrease in the quantity of hair in the telogen phase.

After 86 days of daily application of the product Nanoguard B

• Total hair density increased by 11.9% compared to day 1. This increase was statistically significant.
• The density of hair in the anagen phase increased by 17.1% compared to day 1. This increase was statistically significant
• The Anagen/Telogen ratio increased by 117.7% compared to day 1. This increase was statistically significant.
