Yes, of course. However, if you have previously colored your hair with henna or a color-restorer, you need to wait until your hair has grown out, until these colors fade completely out of your hair, or until your color-treated hair has been cut. Otherwise, the desired results may not be obtained.
Bigen Powder and semi-permanent colors are crucially different with regard to lasting color. Bigen Powder lasts about 4 to 6 weeks, while semi-permanent colors last about 2 to 3 weeks, washing out gradually.
All permanent hair colors, including Bigen Powder, require a preliminary skin allergy test before each use. Your body constitution and condition change every day. Allergic reactions can occur depending on the constitution of the day of use. Please make sure that you do the skin test before each use, even if you have been coloring for years without any problems.
You should carry out the skin test 48 hours before application to see if you are allergic to hair color product, every time you color your hair with permanent hair color product. If you notice any signs of burning, swelling, redness or irritation on your skin during these 48 hours, do not use the product.
No. This product must not be used for dyeing eyelashes or eyebrows. To do so may cause blindness. Avoid contact with your eyes. If product gets into the eyes, rinse immediately and please consult your physician.
With an entire bottle of Bigen Powder and the proper measurement of water (Fill to the "FULL" line of the measuring tray), you can make 2.3 fl oz. of mixture. This amount is good enough to cover from short hair to shoulder-long hair. You may need 2 boxes if you have long hair.
No. Bigen Powder should be applied only on dry hair. Excessive moisture may increase the risk of dripping, which might get into your eyes. To avoid contact with eyes, do not apply color mixture to wet hair.
Yes. As Bigen Powder is a non-ammonia formula that does not require the use of hydrogen-peroxide, it gently deposits color. We suggest waiting two weeks between chemical treatments for minimum hair damage.
Normal processing time is 15 to 30 minutes at room temperature (approximately 68° F to 86° F). The coloring 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 coloring results.
The hair swatches show the coloring 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 color.
No. Color pigments of permanent hair color once oxidized and developed are difficult to remove from hair. It's almost impossible to lighten previously darkened hair with permanent hair color by yourself. For more information, ask for a professional colorist at a salon.
