A cosmetic surgery for hair loss or thinning hair is scalp micropigmentation. Another name for it is a hair tattoo. Microscopic dots of colour are applied to the scalp using very thin, microscopic needles.

The appearance of thicker hair on the scalp is created by these spots. The goal is to make them appear more dense and like actual hair.
By hiding the areas of the scalp's surface where hair loss has already started, it aids in the formation of a new hairline. Scalp micropigmentation is achieved using cosmetic-grade permanent inks.
