Elasticizer Deep-Conditioning Treatment delivers a super-charged boost of elasticity, moisture and strength to fine, medium and coarse hair. This award-winning, pre-shampoo, nutrient-rich formula helps to reduce the likelihood of breakage, leaving hair bouncy, silky, shiny and manageable without weighing hair down. Apply pre-shampoo and then wash out. Before shampooing, thoroughly wet hair and apply in sections. Work into hair with fingertips. Cover with a shower cap and leave for at least 20 minutes (the longer the better). Rinse well and follow with the appropriate Philip Kingsley shampoo, conditioner and scalp toner. Finer hair textures should double-shampoo to remove all product. For best results use at least once a week. Give your hair an enhanced Elasticizer treat by covering with a shower cap and leaving on overnight. Apply Elasticizer before working out, then shampoo out post-gym.
