Objective   

Establish relevant recommendations concerning the latest advances in alopecia, trichoscopy and hair dermocosmetics

Methodology    

• Delphi method: 45 European dermatologists with expertise in trichology give their views on a set of 20 recommendations (4-point Likert scale)
• Consensus is validated when more than 80% of participants have given a score of 1 (strongly agree) or 2 (agree) in relation to the proposed recommendation

Results 

• 100% of proposed recommendations have been validated as a consensus by experts
• 3 recommendations in particular received the approval of 100% of the experts:

Alopecia

• "Mesotherapy combined with dutasteride is a useful treatment for patients with androgenetic alopecia. A protocol must be established."

Dermocosmetics

• "An innovative generation of in vitro models is needed to faithfully reproduce the native hair follicle using long-term organ culture and tissue engineering. These models will be useful for better understanding hair follicle biology and improving alopecia treatment prior to clinical trials in patients."
• "The identification of active ingredients specifically targeting intra- and extra-follicular signaling pathways (such as the Wnt/β catenin pathway, microcirculation, growth factors, cytokines, hormones, enzymes) could help improve the treatment of hair loss."

Conclusion

• The recommendations agreed upon in this study may be useful in the clinical practice of dermatologists
