We put our many decades of experience and scientific expertise into creating a leave-in lotion that actually extends the lifecycle of hair. Fortifying Lotion from 1922 by J.M. Keune is a powerhouse for hair growth. Liposomes significantly increase hair growth – by 25% within just 4 days. Vitamin H (biotin) makes hair’s structure stronger, so hair doesn’t easily break or fall out. Then there’s red ginseng root extract to promote hair growth, stimulating eucalyptus extract - and energizing caffeine to wake up hair roots. Say farewell to delicate, fine and dull hair.
