Nourish and strengthen your hair with this Keratin Conditioner from Daily Defense. The conditioner contains a rich, fortifying oil infused with Keratin (a protein that is crucial to hair strength and maintenance and found naturally within it, but that is often lost due to age, or damage from dyeing and styling your hair) that helps hair to resist breakage, while conditioning every lock of your hair and leaving it with an added shine. The conditioner is particularly good for those who like to style their hair on a regular basis, as it provides protection from heat and chemical damage. For best results, use after washing your hair with shampoo. Your hair will be left looking thicker, richer, stronger, and glossier. If your hair is particularly dry or damaged, consider supplementing your shampoo and conditioner with a hair treatment.
