There's a bit more to dyeing hair than simply coating your entire head with store-bought hair dye and drying it.
For a safe and professional-looking dye job, follow these tips.
Follow Instructions
Follow the specified instruction preparing color mix and stick to the prescribed time on how long you should leave the color in.
Hair Care Before Dyeing
A month before dyeing hair, deep condition it. Dry hair doesn't color well. Before applying hair color, make sure your hair is clean. While you should shampoo to remove any dirt, oil or debris, don't condition it just hours before applying hair dye. Also remove tangles.
If you have split ends, trim them, or this will create messy, uneven hair coloring.
Protection
Wear the gloves that come with your box of dye preparation. If there are no gloves, its a sign that the hair product isn't worth the purchase. Protect skin along the hair line from getting colored by coating it with a thick cream (Nivea, mentioned in picture)
Do the spot test for allergies - apply a tiny bit of dye on your wrist, or near your neck to see if you have an allergic reaction (irritation, redness, inflammation, allergy, hair loss) Do this two days before applying dye.
And to ensure if you've got the right color, try the color out on a few strands.
Staining
For your clothes, you want to wear a towel around your neck. Color may dribble under a T shirt and irritate your skin. Avoid staining your neck and ears by coating liberally with petroleum jelly or cream. Any accidental stains can be wiped off with rubbing alcohol.
Divide, Conquer and Color
For men with long hair, get hair clips. Separate your hair into quadrants (four parts), color each section individually using a small amount of color preparation and thin stripes of color over the entire area. Now clip the colored the colored part.
Go through the other sections, and repeat once more with left over color mix.
Hair Care After Dyeing
Wash with cold or tepid water to avoid hair fall.
Coloring
Don't color your eyebrows to match - that's stupid! And instead of over-dyeing hair, use a few touch ups once every few weeks instead.
