Title : Early improvement and reduction of hair loss and tolerability of an anti-hair loss cosmetic lotion: Preliminary results from a prospective observational study
Abstract:
Hair weakening, reduced density, and increased hair shedding are common concerns in the adult population. In the absence of scalp pathology, topical cosmetic products are widely used to improve hair appearance and quality.
To preliminarily evaluate consumer-perceived efficacy, satisfaction, adherence, and tolerability after 28 days of use of an innovative cosmetic lotion containing turmeric-derived exosomes and plant-based active ingredients.
Prospective, single-arm observational study including adults aged 18–65 years presenting hair weakening and/or increased non-pathological hair shedding. Participants applied 15–20 sprays of the cosmetic lotion daily to the scalp for 28 days. Consumer perception was assessed using structured self-administered questionnaires based on 5-point Likert scales evaluating overall improvement, hair strength, visual density, volume, shine, perceived hair loss, satisfaction, tolerability, and ease of use. Scalp tolerability was assessed through dermatological visual inspection.
Thirty-five participants were included (mean age: 43.3 years; 75% female). At baseline, most reported weak hair, low density and volume, and increased shedding. After 28 days: 60% reported overall improvement, 51% improved strength, 60% increased volume, 51% enhanced shine, and 71% reported reduced perceived hair loss.
Overall satisfaction reached 66%. Adherence was high, with 100% daily use and 94% reporting easy integration into daily routines. Tolerability was favorable: 86% reported no scalp symptoms and 94% described application as comfortable. No serious adverse events were observed.
Daily use of this anti-hair loss cosmetic lotion was associated with early perceived improvements in hair quality and reduced shedding, with excellent tolerability. High satisfaction and adherence support its suitability for continued cosmetic use.
