Weleda's oldest product, newly proved effective! Natural extracts tackle the causes of thinning hair to build more growth and more body, naturally. Take natural extracts of stonecrop, horseradish and rosemary oil, but don't use aggressive chemicals. It sounds like a recipe from days gone by, and in fact, Weleda's Revitalising Hair Tonic has been helping customers since 1921. We've tested it today and it works, thanks to key ingredients that maintain scalp health, carry nutrients to the hair's root and make every hair stronger. Science proved what experience taught us long ago, and a new generation now gets the benefit!
