I asked my hairdresser why her roots never show. She looked at the door, then she opened her purse.

I'd been paying her every five weeks for 14 years, and I was still walking around with a white line down my head by week three. She'd been fixing her own for years, and it took her about ten seconds.

My son Ben is 19 and six foot two. He came home from his first year of college in May, and I met him at baggage claim.

He picked me up off the floor. Then he put me down, looked at the top of my head and said, right there by carousel four, "Mom, what's the white line?"

I laughed. I went to the restroom and held my phone up over my head and took a picture.

I'd never seen the top of my own head. There it was, straight down my part, about as wide as a shoelace. It looked like somebody had run a piece of chalk through my hair.

I run the front desk at a dentist's office. I sit down, and all day long people stand at my counter and look at my part.

I thought about that on the drive home. Every patient. Every delivery guy. The whole of Dr. Lin's staff, who are all taller than me.

It was week three. I go every five weeks, because that's the soonest Marisol can fit me in. I'd thought I had it covered.

Everything I tried in the two weeks that don't count

I moved my part. It doesn't go that way. By lunch it had gone back on its own.

I bought a spray at the drugstore. It worked for about as long as it took to put my white blouse on. There was a brown mist on the bathroom grout, and my hair felt like a doll's.

I bought a little powder with a brush, and I pressed it in like the box said. It looked good until around 2:00. I also had some on my nose.

Then, and I'm not proud of this, I bought a box. Marisol looked at the band it left and said, "Oh, honey."

That night I found my receipts and added them up on the back of one. A hundred and eighteen dollars a visit, plus the tip, ten times a year and a bit. It came to $1,435.

And for two weeks out of every five, I still had a stripe.

$1,435 a year, and for two weeks out of every five I still had a stripe.

"How come yours never show?"

Marisol is 59. She has been coloring hair for 31 years, six days a week. Her hair is as dark as mine.

The next time I was in her chair, she bent over to get something, and I looked at the top of her head. I'd been looking at it for 14 years without thinking.

There was nothing there. No line.

"Marisol, who does your color?"

"Me. Every couple of months, when I get a Sunday."

"Every couple of months? How come yours never show?"

She stopped and looked at the door. She looked at the girl at the next chair. Then she got her purse off the counter, took out a short black stick with a little ridged comb built into the head, and twisted it up a bit.

"Nobody's looking at your whole head," she said. "They're looking at a half inch."

She parted my hair and ran the stick down one side of the part, once, the way you'd draw a line with a ruler. It took about ten seconds. She handed me the mirror.

Half of my part was gone. It was just dark hair. The other half was still chalk.

"What is that?"

"That," she said, "is how I keep my Sundays."

She wrote the name on the back of my appointment card.

It's called, God help us, a Hair Dye Concealer Stick.

Ignore the name. It's a twist-up stick of root color with a comb tip, in three dark shades. It goes on dry and comes out with your next shampoo. There's no ammonia or peroxide, and nothing to mix.

I looked at the front of the card. She'd written me in for seven weeks.

"I'd rather see you every seven weeks," she said, "than lose you to a box."

I ordered mine sitting in the car outside the salon.

Why it always shows up in week three

I made Marisol explain this on my next visit, because nobody ever had.

Hair grows about a half inch a month. So by week three you've got a little over a quarter inch of new growth, and if it's coming in white, it's coming in right next to the darkest thing on your head.

That's why it's worse for us. On a blonde, a gray root just looks like a highlight. On dark hair, the color and the regrowth are about as far apart as they can get, so you see the line sooner. The darker your color, the sooner it shows.

And it only shows in three places. Your part, your hairline and your temples. The rest of your head is covered by the rest of your head.

For years I'd been paying to re-color all of it, on a schedule set by a strip about as wide as a shoelace.

Then I tried it on Mrs. Oakes

Mrs. Oakes is 81. She's been a patient for 22 years, and she's never once kept a thought to herself. In March she told me I looked tired. In April she asked if I'd been ill.

My stick came on a Tuesday. Wednesday was week four. I did my part and my temples before work, and I gave it a minute to set before I put my top on.

Mrs. Oakes came to the counter at 10:15 and stood there, looking down at me, for what felt like most of the morning.

"You look rested," she said.

I went into the supply closet and did a small dance.

"You look rested," she said. I went into the supply closet and did a small dance.

What I do now

My color is still Marisol's. I love what she does, and the stick doesn't do what she does.

Weeks one and two, I do nothing. From week three on, I do my part and temples in the morning, and at night it goes down the drain with my shampoo. Then at week seven I go back to Marisol.

1. Do it on dry hair. Twist the stick up just a little.
2. Part your hair the way you wear it, and run the comb tip along the line once. Stop before you hit skin.
3. Do your temples and hairline the same way. A second pass is easier than taking one off.
4. Give it a minute before you pull a top on, or a few seconds with a hair dryer. I learned that with a white sweater.

At night, shampoo it out. A white pillowcase can pick some up if you don't.

What five weeks turned into

• Week three: The line starts. You do one swipe at the part and go to work. It takes less time than finding your keys.
• Week four: This used to be the worst one. You've stopped parting your hair on the wrong side, and you've stopped wearing the headband.
• Week five: This is when you used to go in. You don't need to.
• Week seven: You go in for your color, and you sit down without apologizing to anyone.

One pass and a comb. Drag the circle to compare.

Who it's for, and who should skip it

It comes in Black, Brownish Black and Coffee Brown, and that's all there is. If your hair is black to medium brown, it was made for you.

If you're blond, red or light brown, skip it. There's no shade for you, and it'll show.

Match it to your color, not your gray. Black is for black hair and the darkest browns. Brownish Black is for dark brown that looks almost black. Coffee Brown is a warm medium brown, and it's darker than you'd guess from the name.

Between two? Marisol says take the lighter one. You can always go over it again.

How it stacks up against what I tried

Keep your colorist. I kept mine.

What I heard in Marisol's chair

Once I knew about the purse, I started asking around. Marisol won't give names, but Patty never minded who knows.

How I'd start if I were you

You buy it from its own page. Pick your shade first.

I'd start with three. One lives in the bathroom, one in my purse and one in the desk at work, because it's always the day you left it at home. Three cost $59.98 and last about 2–3 months of daily touch-ups.

That's less than half of one visit to Marisol.

If you've got family pictures or a holiday party coming, it's delivered in 10 days or less on average, so I'd do it this week.

The guide is a short PDF on matching your shade and making your salon color last longer. The shampoo bar takes the stick out at night, and your hair looks darker wash by wash.

What I wanted to know

Ben came home for Thanksgiving. Week five, as it happens.

I'd spent all summer turning my head to the side when he hugged me, so he'd get my cheek.

He dropped his bag in the hall and picked me up off the floor. When he put me down, he kissed me on the top of the head.

I didn't move.
