FAQ's

General

All permanent hair colours including Bigen requires a skin allergy test before each use since body constitution and conditions are constantly changing. Allergic reactions can occur depending on your body’s constitution of the day of use, so please make sure that you do a skin allergy test before each use, even if you have been colouring for years without any problems.

You should carry out the test following the instructions provided 48 hours before application to see if you are allergic to hair colour product or not, every time you colour your hair with permanent hair colour product. If you notice any signs of burning, swelling, redness or irritation on your skin, do not use the product.
We recommend choosing the colour number that is closest to your initial hair colour, otherwise, go one shade lighter.
Children have more sensitive scalp than adults and the natural barrier function is also weaker due to less secretion of oils, prone to allergic reaction. Therefore, you are strongly recommended not to use hair colour or bleach on children.
Changes in your hormonal balance when you are having your period or pregnant can make the skin more sensitive, increasing the possibility that you will experience skin irritation. On the other hand, if you decide to use a hair colour product during pregnancy, there will be no negative effects on the child.

Normal processing time is 15 to 30 minutes at room temperature (approximately 20°C to 30°C). The colouring process is a chemical reaction that starts when you mix the powder with water. It is not recommended to take too long to apply and process, which may cause hair damage or unexpected colouring results.

The hair swatches show the colouring result when Bigen Powder is applied to 100% gray hair. Bigen Powder tends to come out darker when applying to black hair because it has no lifting action. We recommend that you select 1 or 2 levels lighter than your original, natural colour.
You can store Bigen Powder up to 5 years if it is unopened and stored in a cool and dark place. Once opened it can be stored in an airtight container for up to 12 months in a cool, dry and dark place.
To protect your hair colour from fading, use products that have been specially formulated for colour-treated hair.
