The present invention relates to a process for bleaching hair wherein a water free bleaching composition, preferably in form of a dust free powder or a granulate comprising at least one compound with bleaching andor highlighting effect is mixed with an liquid oxidizing composition wherein water free bleaching powder is passed through a sieve. The oil pump is formed with a main pump and a sub pump. Also disclosed is a storage package which may preferably be used to store functional agents, delivery devices or implants. The second metal region may include a first pronged end and a second end that correspond, respectively, to a first pronged end and a second end of the first metal region. Thus, the interlayer dielectric film has a small quantity of moisture and hydroxyl groups when the first conductive member is embedded in the opening, whereby the embedding characteristic of the first conductive member is improved. The plurality of parallel linear assist features may include a first series of parallel assist features disposed on a first side of the design feature and perpendicularly thereto, and a second series of parallel assist features disposed on a second side of the design feature and perpendicularly thereto.
