Having just given a couple of these scalp massagers as Christmas gifts and watched the recipients use them with many ooh-s and ahh-s, I believe they work because the tips stimulate nerve endings in the scalp. (There are 7 pairs of nerves that end on the scalp.) These nerve endings are connected to larger nerves, which ultimately connect to the brain. The nerve endings pick up messages from the skin being touched and send them to the brain, and the brain interprets them as pleasure, pain, or other sensation.

Essentially it's innervation - light touch 'excites' the nerve endings which can release endorphin's. If you've heard of brushing hair 100 times a day it wasn't to improve the hair but the scalp and relaxation to the entire body. Some massage technicians will use a very light touch sweeping larger parts of the body (back, thighs, chest) to achieve the same after a deep tissue massage. It also triggers vasodilation: a widening of the blood vessels. Since we typically don't have our heads below our hearts daily, this mechanism gets blood flowing easier to the scalp as well as excite the nerves resulting in a more relaxed state of those muscles and endorphins follow suit.
The same can be said for other parts of the body that are 'ticklish', those would be area's where nerves are already sensitive so any light touch fires off a higher peak of innervation resulting in an overload which is not comfortable though that does depend on the state of mind of the person being tickled (they may like it at particular moments and not at other times).
