Achieving healthy and shiny hair involves both prevention of hair care habits such as flat ironing everyday which can rob hair of shimmer, as well as adopting techniques which will amp up the natural play of light over the top of the cuticles. If heat tools are used, then they should be used along with thermal protectants. Your hair should be trimmed 1/2 inch every 6-8 weeks to avoid splits and breakage. If you have relaxed hair, it's best to make sure you have it retouched performed regularly about every six to eight weeks
