Clinical study of the hair growth protocol
CLINICAL STUDY
Hair Growth Protocol
Hair that grows faster & stronger
The Hair Growth Protocol was developed to stimulate hair growth and strengthen the hair fibre.
Its effectiveness was assessed through an instrumental clinical study conducted on 87 women over 3 months in 2023, supplemented by a user test involving 43 volunteers, in order to precisely measure hair growth and the perception of results.
Clinically proven effectiveness
Visibly accelerates hair growth.
+6 cm in 3 months*.
THE METHOD
Clinically proven effectiveness
An instrumental clinical study was conducted on 87 women over 3 months.
According to a pre-defined randomisation list:
- 43 volunteers used the hair growth protocol
- 44 volunteers used a placebo protocol
The complete protocol included:
Shampoo + Leave-in conditioner + Serum.
Hair length is assessed instrumentally using a ruler. The measurement is taken on 10 sampled hairs. It was taken before the application of both protocols and after 3 months.
Standardised digital macrophotographs were also taken to monitor progress during the study.
STUDY RESULTS
Clinical results
The Hair Growth Protocol enables a significant increase in hair growth:
- +6 cm in 3 months vs 3.75 cm for the placebo*
- +60% additional growth vs placebo*
- 100% of volunteers observed increased growth*
