System Professional Extra Lipid Booster is an intensive weekly treatment that helps regenerate and protect damaged hair. Formulated with LipidCode Complex, squalane and PLEX (malic acid), it creates a protective barrier to smooth hair and improve manageability — providing up to 9x more hair protection versus a low-conditioning shampoo. Suitable for damaged to severely damaged and for bleached or highlighted hair. To use: spray onto towel-dried lengths and ends (10–12 pumps for medium to shoulder-length hair), comb through, then blow-dry and style. Use once a week to maintain results from any Lipid Booster+ treatment.
