Untersuchungen zur Wirkung des Nahrungsergänzungsmittels Haarpower auf das exzessive Haaren ansonsten gesunder Hunde

In this multi-centered, placebo-controlled double-blinded study, 21
clinically healthy dogs with a history of excessive shedding
received the food supplement Haarpower containing Spiraea ulmaria
extracts (Haarpower, n=17) or placebo (n=4) for three months. Age,
breed, weight, gender, colour of hair and hair length, feeding
habits and the life style of the animals were recorded. The degree
of shedding was evaluated on a scale from 0-3 and additionally
using a visual analogue scale. Hair specimens were obtained before
and after application. Hairs were weighed, counted and
microscopically examined. None of the dogs on placebo or Haarpower
improved significantly. On the visual analogue scale, owners
estimated the severity of the hair loss at 7.6 (range 4.0 - 10.0)
before therapy. After treatment with Haarpower, the mean severity
score was 5.5 (range 0.0-10.0). Objective parameters obtained from
the hair specimens did not change significantly during treatment
(P>0.1).
