While beneficial in moderation, excessive calcium levels can lead to a calcium overdose that exacerbates the damage in over-processed or bleached hair, resulting in dullness and increased susceptibility to breakage. This hair repair oil treatment offers a dual-action approach: its potent concentration of reparative and nurturing ingredients effectively seals split ends, strengthens hair fibers, and significantly diminishes the persistent dullness often associated with damaged hair.
