Abstract

The invention relates to a shaver head for a wet shaver. The shaver head is arranged at the front end of a handle. A razor blade, in the form of a single or double razor blade, is fastened in a plastic housing. The shaver head has a front guide strip and a rear cover cap. The shaver head includes a shaving preparation, which is dispensed during shaving. The shaver head has a storage device for receiving the liquid shaving preparation, skin care preparation or the like and a dispenser for dispensing the preparation during shaving.
