The main reason is the care that blonde hair requires. During lightening, the natural pigment is removed, making the hair more porous. To keep it healthy and shiny, blondes need special care: nourishing masks, thermal protection, toning products, and sulfate-free shampoos.
When it comes to blonde hair extensions, quality plays an even greater role. Natural blonde donor hair is rare, which means most light shades are achieved through gentle bleaching. The more advanced and delicate the coloring technology, the higher the cost — but the longer the hair maintains its beauty and softness.
