Stress? Hair loss? Yes to both, me too! My experience with Yves Rocher Anti-Chute anti hair loss stimulating shampoo is it significantly cut down the volume of hair pooled at shower drain. It has a strong grass/plant scent during shampooing which takes me awhile to get used to it. Since it is a scalp shampoo, I used it on alternate days. I will always use a floral conditioner or hair mask after shampooing even on lazy days because of the scent. It is probably alright refreshing scent to others as everyone has different level scent adaption. The price is worthy for it's effect. After using it, I stopped using 3 in 1 shampoo which also stated hair loss control because this is much effective and does not cause dryness to scalp. I have been stocking up this during it's sales day. Of course it is cheaper in Europe but it weighs more so nah, singapore outlet sales price is as good.
