Hair Chalking is all on trend now but some girls with black and brown hair are still not sure if the hair chalks word on dark hair. Here if you read this post you will find the answer on this subject: Does Hair chalk work for Dark Hair(Black, Brown or red)?
I must say that if you have got blonde hair, then hair chalking is perfect for you, almost every color work perfectly on your hair. The multi hair chalk colors are very bright when rubbed on blonde hair. But for brown Hair, not all colors are good for them. For example, if your hair is black, then you should avoid below colors:
yellow, brown, black, orange, dark purple. These colors have similar light spectrum as black, they will not look very evident on black hair. The whole effect will not be good. Instead if you have black hair, you should choose hot pink, teal blue, light purple and lime colors. These colors are bright enough to light up the whole strands of hair and bring you the real hair chalking look. Also I have heard feedback from customers claimed for black hair, the colors are not easy to rub on. This is some how true. In this case, I will recommend you to wet your hair first before applying hair chalks. Because the water will make the colors stick to your hair sections much more easily. And also for black hairs, you should rub more colors on hair than blonde hair since the colors will “fade” faster than blonde. ( It’s not real faster but even there’s very few colors on blonded hair, they will still be very evident, but with black hair, it require more volume of hair chalk colors)
For brown and red hair, I think the best colors are puple, hot pink lime and green. As tested, the green color works great on brown hair. The reason is that the two different colors from hair to chalk can provide a binocular disparity. Like black hairs, you also should avoid dark hair chalk colors.
If you want the colors to stay in your hair more steadily and with longer time, you can flat iron your hair a little bit after rubbing on the chalks. This will help the chalk colors combining better with your hair. And make the chalk materials not that easy to fade.
