Fast-acting hair care for strengthening the hair structure. Minimizes hair breakage and restores shine to damaged hair. When time is of the essence... then ""In A Flash"" is exactly the care product your hair needs to strengthen it. The effect on the hair structure unfolds in just seven seconds - new hair bonds are formed and the hair becomes up to 20 times more resistant to breakage when combed. Thanks to its unique formula, the hair care transforms from a liquid to a creamy substance on contact with water, which can be easily worked into the hair where it unfolds its protective effect. Hair that is already damaged or brittle in particular benefits from the lightning-fast effect, which is also color-safe and does not weigh the hair down, resulting in a feather-light, silky shine. PS: There is no pH value stated on the product as it contains so little water that it has no pH value.Application: First wash the hair with Defy Damage Protective Shampoo. Dry the hair a little with a towel.
