Gut Microbiota and Trichoscopic Changes in Women With Telogen Effluvium on a Multifactorial Drinkable Nutraceutical: A Retrospective Observational Study

Condition(s) studied

Investigational drug(s) / intervention(s)

Drinkable multifactorial food supplement containing vitamins, minerals, plant extracts, and other bioactive compounds, formulated to support hair growth and scalp health in women.: Drinkable multifactorial food supplement in liquid form, administered once daily in a 25 mL single-dose vial, for a duration of 180 days. The formulation contains a combination of vitamins, minerals, plant extracts, amino acids, and other bioactive compounds designed to support hair growth and scalp health in women.

Study summary

Telogen effluvium (TE) is a common cause of diffuse, non-scarring hair shedding in women. It is often triggered by physiological stress, nutritional deficiencies, illness or hormonal changes. There is growing interest in the role of the gut microbiota in hair health, through its effects on nutrient absorption, immune regulation and systemic inflammation (the so-called gut-skin axis). However, data on gut microbiota in women with TE are still scarce.

This retrospective observational study will review the medical records of premenopausal women diagnosed with TE who received a multifactorial drinkable nutraceutical as part of routine clinical care at 2 clinics between January 2025 and July 2025. The study has two aims:

1. To describe the gut microbiota profile of these women at baseline \[and after 6 months\], as assessed by \[stool analysis method\].
2. To describe changes in trichoscopic parameters, over 6 months of supplementation \[and to explore whether baseline microbiota features are associated with these changes\].

The study does not assign any intervention: all data were collected during standard clinical practice. Its findings are intended to generate hypotheses for future controlled studies.

Eligibility

Primary outcome measure(s)

• Characterization of gut dysbiosis outcomes — 6 months
  Gus dysbiosis was analyzed with a stool kit test (KyberBioma(R)).
• Characterization of trichoscopic outcomes — 6 months
  Trychoscopy outcomes were measured using a phototrichoscope at the interparietal area. 7 trichoscopy signs were graded (0-3) from 2 evaluators: telangiectasias, punctate vessels, erythema, scaling, follicular miniaturization, follicular hyperkeratosis, fibrosis.
