This oldest product in the all-natural cosmetics line, formulated in 1921, combats the causes of thinning hair to promote more growth and fullness for naturally stronger hair and a healthier scalp. It contains natural extracts from fat hen, horseradish, and rosemary oil, and avoids harsh chemicals. Weleda's revitalizing hair tonic has been helping customers since 1921. It works thanks to key ingredients that maintain scalp health, transport nutrients to the hair roots, and strengthen each strand. Science has proven what experience taught long ago, and a new generation is now benefiting from it.
