Switch shampoos every few days, alternating between volumizing and moisturizing formulas. Unfortunately, fine hair is usually easily damaged. Your hair type will require special care to keep healthy. You should condition after each shampoo. In addition, it is very helpful to deep condition at least once a week.
Color is a great tool to help make fine hair look thicker and healthier.
By working with the base first- your hair cuticles will absorb the color and plump up, creating a thicker feel. Then lowlights and highlights can be added to create a natural effect. Shade upon shade can be added to give a textured appearance. Deep conditioning once a week will help not only in keeping hair healthier, but also in holding any color applied to your hair. This hair type is quite versatile.
