Effektivitet och säkerhet hos en drickbar näringskost för håravfall hos patienter som använder GLP-1/GIP-receptoragonister

Drinkable formulation consisting of an excipient formulation designed to mimic the organoleptic properties of the active product, reproducing its color and texture while achieving a highly similar taste profile.

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, amino acids, plant extracts, and other bioactive compounds designed to support hair growth and scalp health in women +45.

• Patient Reported Outcome using the Hair Shedding Scale: will assess the degree of hair loss among participants. On the day of the visit, they will be shown an A4 sheet with six ranges: between 1 (minimal shedding) to 6 (copious hair shedding).

Subject-reported perception of hair condition assessed using a 12-item questionnaire covering perceived hair density, hair shedding, hair strength, hair volume, appearance, and scalp condition. Each item is rated on a 5-point Likert scale ranging from "strongly disagree" to "strongly agree." Higher scores indicate greater perceived improvement in hair and scalp condition.

Adherence to the Mediterranean diet assessed using the validated 14-item PREDIMED (Prevención con Dieta Mediterránea) questionnaire. The questionnaire evaluates the frequency of consumption of key food groups and dietary habits characteristic of the Mediterranean diet, including olive oil use, fruit and vegetable intake, legumes, fish, nuts, red meat, sugary beverages, commercial pastries, and wine consumption. Each item is scored 0 or 1, resulting in a total score ranging from 0 to 14, with higher scores indicating greater adherence to the Mediterranean diet.
