Formulated as a treatment, especially after washing hair with Fortifying Shampoo, to maintain strong hair, and prevent hair fall-out. 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.Wash hair with Fortifying Shampoo, towel dry, then gently massage Fortifying Lotion into scalp. No rinsing, this is a leave-in treatment. For a fortifying treatment, use 3-4 times per week for 11 weeks. Then maintain by using 2-3 times per week. For preventative action, use 1-2 times a week.
