René Furterer Triphasic Reactional Concentrated Serum

Scalp France Approx. $86

The French pharmacy serum for the thinning that follows a shock, stress, childbirth, a change of season, with niacinamide third on the list and biotin and arginine behind it. Once a week for three months, through a comb applicator. Plant-based and drug-free, which the brand says, so we will too.
