Argan oil is used to enhance the properties of other oils in creams, lotions, serums and especially in hair products where it adds elasticity and shine to the hair. An addition to creams and conditioners of 5% is recommended for normal skin and hair, up to 20% if dry and damaged or over-processed. To boost your shampoo's ability to moisturize, add a few drops to your shampoo before lathering through your hair. For a hot-oil treatment, gently heat just enough Argan Oil to comb through your hair, then wrap with a heated towel for 20 minutes. Shampoo as you would normally. This cold-pressed oil is slow to go rancid and will have a shelf-life of 12 months if kept refrigerated.
