semipermanent

Semipermanent (often written semi-permanent) is a general term used to describe a product, finish, or result that lasts for a limited duration before fading or requiring reapplication. It lies between temporary and permanent options, typically designed to be durable and low-maintenance while remaining reversible or replaceable. In cosmetics, semipermanent products are formulated to degrade or be removed over time by washing, growth, or specialized removal methods, rather than through true permanence.

In hair care, semipermanent color deposits pigment onto the hair shaft with minimal or no lifting of the natural color. The color gradually fades over several wash cycles, commonly after about four to twelve shampoos, and roots may require less frequent reapplication than with permanent dyes.

In nails, semipermanent gel polishes or hybrid polishes cure under UV or LED light to provide a long-lasting, glossy finish. They typically endure about one to three weeks before chipping or growth becomes noticeable, after which removal and reapplication are needed.

In makeup, semipermanent makeup (also called cosmetic tattooing or micro-pigmentation) refers to techniques that place pigment in the dermal layer to provide long-lasting, rather than permanent, cosmetic enhancement. Durations vary from one to several years and may require touch-ups due to fading or changes in skin.

Safety and regulation: Semipermanent products and procedures require proper hygiene, patch testing for allergies, and adherence to regional regulations. Results vary by product type, application method, and individual factors such as hair or skin condition.
