Pureology Hydrate Conditioner provides the special care that colour-treated hair needs. By delivering a sulfate-free concentrated moisturizing formula, this conditioner optimises your colour-retention by preventing fade & improving the overall condition of the hair whilst infusing moisture & shine! Many shampoos & conditioners contain sulfates, which are a major cause of colour-fade. Pureology Hydrate Conditioner has none, making it safe for use on your colour-treated hair! This is the large 1L sized bottle, making it suitable for use in both the salon & the home! Directions for use: After shampooing, massage conditioner into hair & scalp. Wait 1-2 minutes & rinse.
