Olia Oil-Powered Formula
Most dyes put oil in the conditioner. Olia puts it in the colorant. Sixty percent oils drive the coloring process. Sunflower and camellia oils lead the blend. Oils carry color deep into the fiber. That gives richer, longer-lasting results. No ammonia means no harsh fumes. Application smells pleasant. Hair feels healthier after coloring. It looks hydrated and silky. The vegan formula skips animal ingredients. It is also silicone and paraben free. Olia replaces ammonia with an oil delivery system. Flower oils carry dye into the hair shaft. The process feels gentler on the scalp. There is no harsh chemical smell. The oils also condition while coloring. Hair keeps more moisture than with ammonia dyes. The formula still lifts and deposits permanently. It is not a semi-permanent rinse. Gray coverage reaches 100 percent. The oil base helps dye grip resistant grays. After coloring, hair feels smooth, not straw-like. The included conditioner seals the cuticle. Many users switch from Nutrisse for comfort. Sensitive scalps tolerate Olia better. The trade-off is a higher price per box. For frequent colorers, comfort is worth it. The oil scent is light and pleasant. No harsh fumes fill the bathroom during processing.
