Before ROS came out, there were only two types of silicone doll heads; Hard silicone head and soft silicone head. The hard silicone head is hard and realistic, but the mouth can’t open and it doesn’t have oral cavity. Soft silicone head is soft, and it has a simple oral cavity, but no teeth, tongue and uvual. The soft silicone head was once the choice of many buyers who wanted a sex doll with oral functions, but it still had drawbacks. Compared to the TPE head, the soft silicone head is more realistic. But the mouth of the TPE head is more perfect than the soft silicone head, and its mouth can not only add a tongue, but also make a textured texture similar to the inside of vagina/anus. This makes it more exciting to use the doll’s head for oral sex. After the appearance of ROS heads, TPE heads and soft silicone heads were defeated in terms of oral function.
Do you know what is ROS head?
ROS means Real Oral Structure. It’s an upgraded version of the silicone sex doll head. It has teeth, a tongue, and a uvual which make the head a super realistic oral experience. Most heads with this upgrade also come with a movable jaw. With this function, the head can open and close her mouth.

However, ROS heads also have drawback. All ROS heads are made of soft silicone. This means that if you make implanted hair, eyebrows and eyelashes into the ROS head, they will fall easily. It doesn’t mean you can’t make hair implants for ROS heads, but you need to take the risk of hair falling out.
