Telogen Effluvium
Conditions
Brief summary
Controlled, randomized, double blind study, for the evaluation of tolerance and trichological efficacy of a food supplement: Bioscalin® new formulation versus reference formulation currently on the market and placebo
Detailed description
Aim of the study was to evaluate clinically and by non-invasive instrumental measurements the trichological activity of a food supplement taken for 3 months by subjects of both sexes, aged between 18-60 years, affected by telogen effluvium, with a percentage of hair in anagen phase \< 75%. In particular the study foresaw the evaluation of the trichological activity of the Bioscalin® new formulation with Galeopsis Segetum in comparison to a reference product currently on the market and to placebo. It was also aim of this study to evaluate treatment tolerance.
Interventions

Total duration of the study was 4 months; each subject, took by mouth two capsules/die of placebo at breakfast and one tablet/die of study product at lunch for the first 3 months of the trial.
DIETARY_SUPPLEMENTReference product
Total duration of the study was 4 months; each subject, took by mouth two capsules/die of reference product at breakfast and one tablet/die of placebo at lunch for the first 3 months of the trial.
DIETARY_SUPPLEMENTPlacebo
Total duration of the study was 4 months; each subject, took by mouth two capsules/die of placebo at breakfast and one tablet/die of placebo at lunch for the first 3 months of the trial.

Exclusion criteria
* Pregnancy (for female subjects); * lactation (for female subjects); * subjects not in menopause who does not use adequate contraceptive precautions in order to avoid pregnancies during the study; * subjects not in menopause who do not accept to perform the pregnancy test during the basal visit, after 2 (T2) and 3 (T3) month-treatment; * change in the normal habits regarding food, physical activity, physical activity, hair and scalp cleansing during the month preceding the test; * sensitivity to the test product or its ingredients (to be assessed by the investigator during the baseline visit).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline of the percentage of hair in anagen phase | Basal visit (T0),1 month (T1), 2 months (T2), 3 months (T3), 4 months (T4). | Percentage of hair in anagen phase (anagen hair grow \> 0,3 mm/die ) was calculate by TrichoScan software on the microscopic images (with 20X magnification) captured with FotoFinderDermoscope. |
| Change from baseline of the hair density | Basal visit (T0),1 month (T1), 2 months (T2), 3 months (T3), 4 months (T4). | Hair density (hair number/cm2) was calculate by TrichoScan software on the microscopic images (with 20X magnification) captured with FotoFinderDermoscope. |
| Change from baseline of the percentage of vellus hair | Basal visit (T0),1 month (T1), 2 months (T2), 3 months (T3), 4 months (T4). | Percentage of vellus hair (vellus hair has a diameter \<0.04 mm)was calculate by TrichoScan software on the microscopic images (with 20X magnification) captured with FotoFinderDermoscope. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hair parting test | Basal visit (T0), after 1 (T1), 2 (T2) and 3 (T3) month-treatment and a follow-up visit 1 month after the last food supplement assumption (T4 months). | Evaluation of hair thickening |
| Sebometry | Basal visit (T0), after 1 (T1), 2 (T2) and 3 (T3) month-treatment and a follow-up visit 1 month after the last food supplement assumption (T4 months). | Measurement of surface lipid level |
| Videodermatoscopy | Basal visit (T0), after 1 (T1), 2 (T2) and 3 (T3) month-treatment and a follow-up visit 1 month after the last food supplement assumption (T4 months). | Evaluation to visualize any morphological alteration/variation of the hair often imperceptible to the naked eye |
| Pull test | Basal visit (T0), after 1 (T1), 2 (T2) and 3 (T3) month-treatment and a follow-up visit 1 month after the last food supplement assumption (T4 months). | Evaluation of tensile strength of the hair |
