Clinical study of the Progressive Anti-Hair Loss range
CLINICAL STUDY
Progressive Anti-Hair Loss range
Visible reduction in age-related hair loss
The Progressive Anti-Hair Loss range was developed to help reduce hair loss linked to age and heredity, which causes progressive thinning of the hair fibre and sparse hair.
Thanks to formulas enriched with targeted active ingredients, it helps strengthen the hair fibre, improve hair resilience and preserve hair density.
Clinically proven efficacy
Each product in the Progressive Anti-Hair Loss range has been the subject of a dedicated clinical study, conducted under dermatological supervision on volunteers experiencing progressive hair loss.
The products were applied for 3 months to precisely measure the reduction in hair loss.
ASSESSMENT PROTOCOLS
The method
The assessment is based on scientific techniques that objectively measure hair loss and its progression.
Wash Test
This method precisely quantifies the number of hairs lost during washing. Shed hairs are collected and counted, providing a reliable measure of the intensity of hair loss.
Procedure
- Volunteers do not use shampoo for 48 hours.
- Hair is washed over a basin fitted with a collection device to collect and count shed hairs
Phototrichogram
(scientific analysis of the hair cycle)
The phototrichogram enables precise analysis of the hair growth cycle.
Procedure
- A small area of the scalp is shaved.
- The hairs in the shaved area are dyed to make them clearly visible.
- A photograph is taken using a dermatological camera.
- A second photograph is taken 48 hours later.
The images are then analysed using specialised software.

Analysis of the hair cycle
The software measures several scientific parameters:
Hair density
Total number of hairs per cm².
Hair cycle phase
Each hair is classified according to its phase:
- Anagen phase: growth phase
- Telogen phase: shedding phase
Anagen/telogen ratio
The higher the number of hairs in the anagen phase and the lower the number of hairs in the telogen phase, the more hair loss is reduced.
