How to check the anti-counterfeiting of Dove shampoo
Dove shampoo conditioner bottles are curved, not rigid lines. The fake bottle is too straight, and the corners lack radian and are not round. The trademark printing of Dove Shampoo is very distinctive, and the font is specially designed, which is not available in general computers. The counterfeit Dove trademark is printed in a heavy color, so it is unnatural to use a pen. Open the lid of the genuine product and you can see that there is no burr where the shampoo comes out. Because of poor processing technology, fakes sometimes have burrs and adhesions.
How long is the shelf life of Dove shampoo?
The shelf life of shampoo is generally two or three years when it is unopened, and it should be used up as soon as possible within half a year or one year after it is opened, because shampoo contains a lot of surfactants, which will fail over time and will not play a cleaning role after failure. Shampoo is not easy to deteriorate after opening, but it should also be preserved to avoid pollution, humidity, low temperature and high temperature, and used up as soon as possible within the time limit to avoid damage to the body caused by deterioration.
Can shampoo still be used after it has expired?
You can't. Shampoo contains a lot of chemical components, and the chemical components of shampoo may change after the shelf life. If you use it, the scalp pores will open when you wash your hair, and you may absorb a certain amount of chemicals. You may not see any harm in a short time, but there will be some adverse reactions after long-term use.
