Bond Builder Lipid Shield replenishes lost essential oils which coat each hair strand, protecting the cuticle against dryness and damage caused by factors such as UV and heat. Inspired by the hair's natural lipid shield, the fast-absorbing, non-greasy formula contains biomimetic ingredients and lightweight oils to restore your hair's first line of defence and protect bonds in the cortex. Shake well before use. Gently tilt the bottle and tap the base to dispense 5-6 drops into the palm of your hand. Apply to mid-lengths and ends of towel dried hair. Short, fine, or unprocessed hair may require fewer drops. Long, coarse, or heavily processed hair may require more. Start with a smaller amount and add more as needed.
