The miracle of Mediterranean olive oil and wheat protein are combined in Dalan d’ Olive PARABEN FREE Repairing Care Shampoo to restore natural health to your hair. Independent tests carried out by internationally accredited laboratories have proven that d’Olive shampoo repairs damaged hair, deeply nourishes and strengthens them from root to tip, protecting it from split ends, regaining the moisture it has lost within 2 weeks. It is added with Wheat Protein that greatly increases the hair’s ability to retain moistures, adds volume to hair, reduces the hair’s porosity, increases strength, initiates regeneration and improves smoothness. Hair washed with an olive oil shampoo will have increased hydrated levels due to the natural fatty acids present in olive oil – espcially oleic acid. These acids aid in the nourishment by enveloping each hair and the scalp in a protective barrier that helps to lock in moisture. While the fatty acids are taking care of the inside of the hair, Vitamin E and Vitamin K are working from the outside. Both Vitamins E and K protect the hair from the environmental elements like poor air quality and sun damage, that cause dry scalp and dry hair. Even after a few shampoos with olive oil shampoo there are noticeable differences in shine and hydration of the hair. Those with a dry flaky scalp will start to notice less dandruff and those with an itchy scalp will notice the need to itch comes lessens. With repeated use, the scalp will become more normalized and issues with dryness, itchiness, and flakiness will soon disappear. When coupled with an olive oil conditioner, the healthy hair benefits are maximized. **Comparison of hair treated 3 times a week for 4 weeks with d’Olive Repairing Care Shampoo against untreated hair by an internationally accredited laboratory.
