Efficacy and Safety of Mesotherapy With Minoxidil 0.5%/2ml for Androgenetic Alopecia in Female Patients

Phase 3
Conditions
Female Pattern Alopecia
Interventions
Drug: Saline
Registration Number
NCT01655108
Lead Sponsor
Brasilia University Hospital
Brief Summary

This study aims to investigate the effectiveness and safety of mesotherapy for the treatment of female pattern alopecia.

* Sixty female subjects between 18 and 65 years diagnosed with female pattern hair loss will undergo mesotherapy sessions weekly for ten weeks.

* One group will receive 0.5%/2ml minoxidil application and a control group will receive application of placebo (saline 0.9%).

* Biopsy of the scalp, trichogram and trichoscopy (Fotofinder) will be performed before and 08 weeks after treatment as a method objective evaluation of the response

Detailed Description

This is a trial that aims to analyze the efficacy and safety of mesotherapy with minoxidil 0,5% versus placebo for androgenetic alopecia in female patients.

The patients and the investigators who analyzes complementary exams are blind.

* Clinical criteria, photo, 4mm biopsia, trichogram and trichoscopy are perfomed before patients are randomized into two arms :

1. Group 1 (Placebo):

30 patients who will have intradermal injections in the scalp of saline 0.9%

2. Group 2 (Active Drug):

30 patients who will receive intradermal injections in the scalp with minoxidil 0.5%/2ml

Eight weeks after the last session patients will be recruited for repeat the exams and perform a self-assessment of both the effect on hair growth and the effect on hair loss.

GroupInterventionDescription
SalineSalineAfter having been properly diagnostic as having androgenetic alopecia, through biopsy of the scalp, trichogram and trichoscopy and randomized in the placebo group, thirty women will be subjected to intradermal application (mesotherapy) of saline; ten sessions will be held at weekly intervals. Eight weeks after the last session will be repeated all the tests for comparison of results.
Minoxidil 0.5% /2mlMinoxidilAfter having been properly diagnostic as having androgenetic alopecia, through biopsy of the scalp, trichogram and trichoscopy and randomized in the drug active group, thirty women will be subjected to intradermal application (mesotherapy) of minoxidil 0.5%/2ml; ten sessions will be held at weekly intervals. Eight weeks after the last session will be repeated all the tests for comparison of results.
Primary Outcome Measures
NameTimeMethod
Increase in hair densitySixteen weeks

Six weeks after the last session of mesotherapy patients will be subjected to control examinations to evaluation of results. Scalp biopsy to determine the terminal-vellus ratio, trichogram to assess the percentage of anagen hair, telogen and dystrophic and Trichoscan will be performed to see if there was improvement in hair density

Secondary Outcome Measures
NameTimeMethod
Mesotherapy safetysix months

In each session of mesotherapy, blood pressure and cardiac frequency at baseline and 10 min after application of the drug will be measured to assess the safety profile of the solution of minoxidil to 0.5% when injected intradermally.

Any adverse effect reported will be recorded on specific clinical form
