Our black brown hair salons are carefully prepared from petrolatum, ethylhexyl palmitate, and polyisobutylene. Designed specifically to form pigment adhesion layers for enhanced tinting durability. How to use is extremely convenient: Clean your hair and keep it dry. Turn the knob at the bottom to get the right amount of paste, then apply the product evenly on the hair and roots until the entire hair is covered. And it is a rugged design that can be applied without additional tools. Color can be done with a touch of light, it is easy to operate without experience.Net content: 20gProduct name: Black and brown hair salonKeywords: Hair CareGross weight: 51.5gIngredients: Polyester, ethylhexyl palmitate, polyisobutylenePackaging size: 8.4*4.8*2.2cmProduct size: 8.2*4.6*2cmBox meter: 56*36*21.5cmWeight of one box: 20.22kgShelf life: 3 yearsStorage method: Please store it in a cool and covered area
