Will this shampoo weigh down my fine hair or leave it feeling flat?

This formula is designed specifically for fine or weak hair that tends to look limp after washing. The cleansing base removes excess sebum and buildup at the roots, which is what actually gives hair lift and freshness. Meanwhile, the coconut milk and BIO argan oil work on the lengths and ends: coconut milk helps smooth the hair surface so strands reflect light better and feel less rough, while argan oil adds a very light coating that reduces friction when combing. Because these ingredients are delivered in a shampoo (not a mask or heavy conditioner), they rinse off sufficiently that they don't build up or weigh hair down. If you have very fine hair, focus the shampoo on your scalp and let the foam run down the lengths — that's usually enough conditioning for the ends without overloading them.
