Stain Hybrid Dye colours both the skin and the brow hair leaving a flawless brow stain for up to 10 days on the skin and up to 6 weeks on the hair when used with the Airbrush or brush application method. The longevity depends on factors such as the client's skin type, pH level, lifestyle, skincare routine, and environmental influences. Additionally, the artist's application technique and aftercare can definitively impact the final result.
