HVP + Brazil Nut Oil Complex HVP + Brazil Nut Oil Complex. Brazil Nut Oil provides superior moisturisation and shine to dry and damaged hair. Brazil nut oil reduces split end formation and with its Vitamin E content also gives massive anti-oxidant protection to coloured hair. Selenium, another essential mineral found in abundance in Brazil Nut Oil, helps boost hair growth. It also contains Castor Oil which helps to smooth the protective hair cuticle and adds immense shine. Because castor oil is both a hydrator and a humectant, it helps to maintain the hair's moisture levels by sealing in hydration. How To Use Apply to towel dried hair, massage into stressed areas, comb through and leave for 5 minutes before rinsing. In case of contact with eyes, rinse them immediately.
