I'm always experimenting with different hair colors, my favourite being bright crazy colors. Stargazer sell hair mascara in a range of different colors like bright yellow, green and pink. I've always liked hair mascara and applying these takes me back to the 90s. I got two of their hair mascaras in bright pink and yellow.
The product comes in tubes like regular mascara and has a mascara wand to apply the color with. The best way to apply this is to find a section of hair you would like to color and then run the wand through it. There was plenty of pigment in this mascara so two applications was all I needed to get bright color in my hair.
The mascars only give you temporary color that washes out in one wash. If you want something that lasts a bit longer than Crazy Color or Stargazer's Semi Permanent is better for that. I quite liked the hair mascaras as you can do a lot with them. They do make your hair feel a bit dry on the section you applied them but as it is only a one wash color it isn't that noticeable.
These mascaras usually go for about £3.00, so a good price for having bright color.
