COLLECTION: ProYou / Unruly, frizzy hair is a common problem. It tells us that the hair fibre may be dehydrated and is therefore more sensitive to humidity in the air. This causes moisture from the air to penetrate the hair and lead to unwanted frizz. Sometimes, these characteristics can be difficult to control. In addition to the daily moisturizing/nutrition care, it is necessary to use finishing products with a disciplining action. These products are practical because they do not need to be rinsed and offer control of unruly hair and protection against humidity while enhancing shine and softness. The Frizz Block technology of Revlon Proyou The Tamer Sleek controls the frizz, disciplining the rebellious strands and at the same time creating an elegant shiny effect.
