Plain-English summary
Four dogs with hair loss after being clipped were treated with a technique called microneedling, sometimes combined with platelet-rich plasma (PRP), to help their fur grow back. After three months, all the dogs showed improvement, and those treated with both microneedling and PRP had better results. By six months, three of the dogs had almost complete regrowth, while one dog showed slower progress but improved significantly by twelve months. Both treatments were effective in helping the dogs regain their hair, with the combination showing quicker results initially.

Abstract
BACKGROUND: Post-clipping alopecia often has a clinically poor response to therapy and prolonged alopecia is a source of anxiety for some owners. In humans and dogs, superficial microtrauma via a microneedling (MN) device induces mechanical stimulation of the hair follicle with resultant hair regrowth. Human studies suggest that concurrent application of platelet-rich plasma (PRP) with MN induces more rapid regrowth of better-quality hair than microneedling alone. HYPOTHESIS: Microneedling with PRP will induce more rapid regrowth of better quality hair. ANIMALS: Four unrelated client-owned dogs diagnosed with post-clipping alopecia. METHODS AND MATERIALS: This was a prospective study. The affected site was divided in half, with the first half treated with MN alone and the second half treated with MN + PRP. Hair regrowth was assessed by clinician and owner using a hair growth assessment scale (HGAS) at one, three, six and 12 months. RESULTS: At three months, all dogs had improved and three exhibited greater hair regrowth on the MN + PRP side. A similar response was noted bilaterally in three dogs, which had improved by 76-100% at six months and remained unchanged at 12 months. One dog improved by < 26% at six months, but had> 50% re-growth by 12 months. The small sample size precluded statistical analysis. CONCLUSIONS AND CLINICAL IMPORTANCE: In dogs with post-clipping alopecia, MN + PRP appeared to induce more rapid hair regrowth than MN; however, overall results were visibly equivalent by six months regardless of method. Both MN and MN + PRP proved successful for treating post-clipping alopecia.
