René Furterer's Triphasic Length Accelerating Serum revitalizes the scalp for visibly longer, stronger hair. Its expert formula combines propolis, a keratin booster, and caffeine to activate growth from the root, delivering visible results in just one month. Thanks to its ultra-light, non-greasy texture, this serum is easy to apply daily to dry or damp scalps without rinsing. Made in France in recycled packaging, it fits perfectly into a responsible and effective hair care routine.
