This removes dirt, excess oil, and product buildup, allowing the mask's nutrients to penetrate the hair shaft more effectively. Avoid using conditioner beforehand, as it can create a barrier that hinders absorption. 2.Proper Application and Quantity: Apply an appropriate amount of the hair mask, usually starting with a generous dollop the size of a golf ball for medium - length hair. Focus on the mid - lengths and ends, where hair is typically drier and more damaged. Gently comb through with a wide - tooth comb to ensure even distribution, and avoid overloading the roots, which can weigh down your hair. 3.Timely Rinsing and Frequency: Do not leave the hair mask on for longer than the recommended time stated on the product label, usually 5 - 15 minutes. Over - leaving it may cause product residue buildup or make your hair greasy. Use the rinse - off hair mask 1 - 2 times a week; excessive use can disrupt the scalp's natural oil balance and reduce the mask's effectiveness over time. Package includes 1 * Collagen Hair Mask 100ml
