Plasma Rich in Growth Factors (PRGF-Endoret)in the Treatment of Androgenetic Alopecia

A Pilot Randomized, Double-blind, Placebo-controlled Clinical Trial to Obtain Preliminary Data on Efficacy and Safety in the Application of PRGF-Endoret by Mesotherapy, in the Treatment of Male and Female Androgenetic Alopecia of Over 6 Months Duration.

• Androgenetic alopecia (AGA) or common baldness is the most common cause of hair loss in both men and women and is caused by the action of androgens in genetically predisposed individuals.
• This clinical trial was designed to evaluate the efficacy and safety of using a preparation of autologous plasma rich in growth factors (PRGF-Endoret) in the treatment of androgenetic alopecia.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in Hair density at three months (number of hairs per cm2)	Hair density (number of hairs per cm2) will be measured for each treatment group	3 months post-treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hair Width (micrometers)	Hair width will be measured for each treatment group	Basal, 1, 2, and 3 months post-treatment
Anagen/telogen ratio	Hair cycle has different phases. Two of the most important are anagen (active growth phase of hair follicles) and telogen (resting phase of the hair follicle). This secondary outcome measure allows to measure the efficacy of the PRGF-Endoret treatment.	Basal, 1, 2, and 3 months post-treatment
Terminal Hair Density	Terminal hair density will be established for each one of the treatments	Before each one of the treatments and 1, 2 and 3 months post-treatment.
Vellous hair density	Vellous hair will be measured for each treatment group	Basal,1, 2 and 3 months post-treatment
