Schwarzkopf BLONDME Premium Developer 2% 7 Vol. 1L is a professional hair developer that goes together with Schwarzkopf BLONDME hair color and lightening products. Moreover, it features a low-strength formula, providing controlled lifting power and color results for blonde hair, which has a more delicate hair structure. The 2% developer, also known as 7 volume, falls within the lowest strength range of the BLONDME range. Therefore, it is ideal for subtle toning, refreshing, or enhancing existing blonde shades without causing excessive lightening or damage to the hair. Despite its lifting power, this developer is also gentle on the hair. In fact, it contains ingredients that protect the hair during the coloring or lightening process, minimizing damage and maintaining hair health.
