Clinical-instrumental Evaluation of the Efficacy of Two Dietary Supplements Claiming Anti-hair Loss Properties and Hair Strength Improvement. A Double-blind, Randomized, Placebo-controlled Study

The study is aimed to assess the efficacy of two dietary supplements composed of a Wheat Polar Lipid Complex (WPLC) in oil or powder form in reducing hair loss and improving hair aspect.

Study Overview

• Status: Completed
• Conditions: Healthy Volunteers
• Intervention / Treatment: Dietary supplement: Placebo; Dietary supplement: Wheat Polar Lipid Complex Oil; Dietary supplement: Wheat Polar Lipid Complex Powder

Detailed Description

A double blind, parallel groups, placebo-controlled study is carried out on 90 healthy female subjects aged between 18 and 65 years old with all hair type showing diffuse and temporary hair shedding with a proportion of hair in telogen phase >15%.
