Detailed answer

Cleansers are not specifically designed or formulated for treating dull nails. Dull nails usually indicate dryness or lack of moisture, and cleansers can potentially strip the natural oils from the nails and make them even drier. To improve the appearance of dull nails, it is recommended to use moisturizing nail treatments or specialized nail oils that are specifically designed to hydrate and nourish the nails. These products help restore moisture and promote healthier, shinier nails. Additionally, maintaining a balanced diet, avoiding excessive use of nail products containing harsh chemicals, and protecting nails from excessive exposure to water and harsh detergents can also be helpful in preventing or reducing dullness.
