TLDR The supplement improved hair health and reduced shedding in people with telogen effluvium.

The study evaluated the effects of Pilopeptan ® Intensive, a nutritional supplement containing hydrolyzed collagen, Group B vitamins, and zinc, on 343 patients with telogen effluvium (TE). After a 1-month treatment, significant improvements were observed in hair thickness, amount, shedding, strength, brightness, and softness, with sustained benefits even after a 30-day washout period. The pull test confirmed reduced hair shedding, and participants reported high satisfaction and adherence, with only mild side effects in 10 patients. The findings suggest that Pilopeptan ® Intensive may be an effective nonpharmacological treatment for TE, though further research is needed to confirm long-term efficacy and safety.
