    why skip conditioner before the mask?
    Is the K18 PRO mask and take-home mask the same? 
    How often can I reapply HeatBounce?
    Will the molecular repair hair oil leave buildup or weigh down hair?

      Great protectant!

      A little goes a long way with this protectant. My hair is noticeably soft and easy to manage. I am 62 swim everyday and live in florida.

      Great heat protectant

      I use this now after every wash to protect before styling. Works wonders and I can tell it is protecting my hair because my hair strength is improving.

      A miracle

      Best product there is to dry your hair. Either by blow drying or curling iron. Simply the best.
