There are several things to consider, how you can make the color last longer:
First wash your hair and then dry prior to applying the product. Gray hair can take longer to absorb hair color. So, when coloring your hair, apply dye to the gray areas first. It may take up to 45 minutes for the color to penetrate gray hairs; with careful timing, you can achieve even coloring throughout your hair. Note, if you have stubborn gray, the duration may need to extending to 1 hour and 30 minutes.
Instructions for mixing the tint and the activator (fixative) should be followed as per the instructions. Mix well!
The hair’s ability to absorb the product is also dependent on how long the color lasts. You may want to consider leaving the dye on longer, giving the hair more opportunity to absorb the dye into the pours of the hair.
Brush and comb your hair prior to applying the tint. You need to make sure your hair is tangle-free. If your hair is tangled, the color may apply unevenly.
Remember, if you wash your hair frequently with harsh shampoos and conditioners, the dye will begin to fade sooner.
For darker colors, increasing the applications duration from 20 to 30 minute to 35 to 45 minutes, will increase the colours intensity and richness, making the colour look darker and stronger.
Prepare Your Hair For coloring
Don’t cut your hair on the same day before coloring, because your hair has split ends, it will affect the quality of your hair color.
Do not moisturize too much using heavy conditioners or moisturizers just a couple of days before coloring your hair, or the pours of the hair shaft may become blocked and may not effectively absorb of the color.
Do not use any styling aids such as hair spray, mousse or gel nor leave-in conditioner of any kind at least a few days before applying a tint to your hair. Use a light shampoo only to clean the hair of all products.

If you have thick and abundant hair, be sure to buy at minimum two boxes of SANOTINT hair dye. That which you do not dispense, from the tube and bottle, can be recapped and used within the next 4 months.
If you have lighter colored hair and you are applying a darker color, be sure that you uniformly comb through the color from your roots, all the way to the tips of your hair.
