Avoid them and you can get professional results with home coloring.
YOU HAVE TOO CLEAN HAIR
Don't wash your hair the day you plan to color it. A little natural oil on the hair and scalp will protect against irritation and burning.
YOU RADICALLY CHANGE YOUR HAIR COLOR
When coloring at home, try to change the shade by only one or two tones. If you want a more noticeable change in color, it's better to go to the salon.
YOU COLOR YOUR EYEBROWS WITH HAIR COLOR
First, it's not safe for the eyes. You risk your eyesight. Secondly, the color of the eyebrows will in any case be different from the color of the hair, since they have different thicknesses.
YOU RINSE THE PAINT TOO FAST
If you have gray hair that is difficult to color, try dyeing one strand first to understand how long it takes to get the desired color. This way you don't have to paint the whole head to find out that the current paint won't give the desired effect.
YOU DO NOT FOLLOW THE INSTRUCTIONS
Carefully study the instructions. Some manufacturers recommend first adding water and lathering the product applied to the hair. This is an important step that allows you to distribute the paint and make it easier to wash off. If you skip it, you risk leaving some of the dye on your hair and skin.
YOU ARE OVERDOING YOUR GRAY HAIR
If less than a third of the hair is gray, there is no need to use permanent dye. Even temporary dye will provide the desired effect and at the same time damage the hair structure less, give it shine and smoothness. Also, choose colors that have the words "natural" and "neutral" in their names: they are better suited for dyeing gray hair.
YOU ONLY USE ONE COLOR
With just two different shades, you can achieve a more natural result even at home. The very effect of a wig, when dyed hair ceases to look like natural hair, occurs if, with constant dyeing, ammonia molecules are practically built into the hair. In this case, the hair becomes too porous, and the pigment oversaturates them.
To achieve a natural effect, first paint over the regrown roots with permanent ammonia paint. Dry your hair with a towel, and then paint over the entire volume of hair with ammonia-free paint one tone lighter. Leave it on for 10 minutes, rinse and condition.
