Wash hair less often, as over washing will fade color. Always use color protecting, heat protecting and anti frizz products when styling hair. Make sure to use hair treatments masks at least once a week for moisture, color protection, and shone enhancement. Try to avoid products with sulfates (SLS or SLES), parabens, sodium chloride, and petrochemicals.
