title: North American Virginian Witch Hazel (Hamamelis virginiana): Based Scalp Care and Protection for Sensitive Scalp, Red Scalp, and Scalp Burn-Out.
abstract: BACKGROUND
  A sensitive scalp is a frequent problem in daily clinical practice and often represents a major challenge for dermatologists.
  
  
  OBJECTIVE
  The objective was to evaluate the efficacy of a Northamerican Virginian Witch Hazel (Hamamelis virginiana)-based shampoo and tonic (Erol(®) Energy) for treatment of the sensitive scalp.
  
  
  METHODS
  Retrospective observational study of male and female patients given Erol(®) Energy products in the period between August 2010 and December 2013 at the Center for Dermatology and Hair Diseases Professor Trüeb to treat irritable scalp conditions or as concomitant treatment to minoxidil therapy for androgenetic alocepia.
  
  
  RESULTS
  Shampoo was applied successfully in 1,373 patients (1,233 women and 140 men). Patients reported improvement of subjective manifestations of irritation and rated tolerance of both products as good to excellent. During this period, 369 (26.9%) have received Erol(®) shampoo more than once.
  
  
  CONCLUSIONS
  The choice of appropriate hair-care products represents an important aspect in the management of the sensitive scalp and related conditions. With the Erol(®) Energy hair-care products, the advantages of H. virginiana are available for successful treatment of the scalp, especially in the context of problems associated with red scalp, scalp burn-out, and the use of topical minoxidil for androgenetic alopecia.
