As a styling and treatment oil from Biolage, All In One Oil smooths frizz, adds shine and tames flyaways with a lightweight, non-greasy texture. Suited for dry, damaged or color-treated hair, it works as a leave-in serum or pre-wash treatment. Fragrance-forward finish suits those who prefer scented products; the formula targets manageability and hydration without weighing strands down.
