The debate over how often to wash hair is a tale as old as time—well, almost. For one family, this debate has turned into a heated argument, with a mother-in-law washing her hair twice a day and sparking concern that it might be too much. Let’s dive into the science of hair care, the risks of over-washing, and how to find the ideal routine for maintaining healthy locks.
Understanding Hair and Scalp Health

Healthy hair starts with a healthy scalp. The scalp naturally produces oils, called sebum, which protect and nourish your hair. While these oils are vital, excessive washing can strip them away, leaving your scalp dry and irritated. Imagine washing your favorite sweater too often—it might still look good at first, but over time, it loses its softness and becomes worn out. Your hair works the same way.
The Science Behind Shampooing
Shampoos are designed to clean your hair and scalp by removing dirt, oil, and product buildup. But here’s the kicker: not all shampoos are created equal. Some contain harsh detergents that cleanse too aggressively, while others are gentler, focusing on moisture and repair. The frequency of washing should take into account the type of shampoo being used and its effect on your scalp.
For instance, if your shampoo is sulfate-heavy, washing twice a day could be akin to scrubbing a non-stick pan with steel wool—effective in the short term but harmful in the long run.
The Risks of Over-Washing Hair
Washing your hair too often might sound harmless, but it can lead to several unwanted outcomes:
- Dryness and Breakage: Over-washing removes natural oils, leaving your hair brittle and prone to split ends.
- Irritated Scalp: A stripped scalp can become itchy and inflamed, potentially leading to dandruff or eczema.
- Oil Overproduction: Ironically, over-washing can make your scalp produce more oil to compensate, creating a never-ending cycle of greasy roots and frequent washes.
Think of it like overwatering a plant—what starts as good intentions can quickly turn into drooping leaves (or, in this case, frizzy strands).
Signs Your Hair Might Be Over-Washed
How can you tell if your hair care routine is too intense? Here are some telltale signs:
- Hair feels overly dry or frizzy
- Split ends appear more frequently
- The scalp feels tight, itchy, or flaky
- Hair lacks shine and looks dull
- Strands become unmanageable, no matter how much product you use
If you’re ticking off these boxes, it’s time to reassess your routine.
Expert Opinions on Hair Washing Frequency
So, what do the professionals say? Most experts agree that hair washing frequency should be tailored to your individual needs. Here’s a general guideline:
- Normal Hair: 2-3 times a week
- Oily Hair: Every other day or daily if necessary
- Dry or Curly Hair: Once or twice a week
However, lifestyle factors like exercise, climate, and product use play a big role. For instance, if you hit the gym daily, you might feel the need to wash your hair more often. Dermatologists and trichologists recommend consulting a professional for a personalized approach.
Factors That Affect Hair Washing Needs

Your hair type, scalp condition, and lifestyle all influence how often you should wash your hair. Let’s break it down:
- Hair Type: Fine hair tends to get oily faster, while coarse or curly hair holds onto moisture better, requiring less frequent washing.
- Lifestyle: If you live in a hot, humid climate or sweat a lot, more frequent washing might be necessary.
- Scalp Condition: A flaky scalp might benefit from targeted treatments rather than constant washing.
It’s all about balance—what works for one person might not work for another.
Finding the Right Balance for Your Hair
Striking the right balance takes a bit of experimentation. Start by reducing how often you wash your hair and observe how your scalp and strands respond. If they feel healthier, you’re on the right track. You might also consider incorporating alternatives like dry shampoo to extend the time between washes or co-washing (using conditioner instead of shampoo) for a gentler cleanse.
Tips for Maintaining Healthy Hair

Whether you’re washing twice a day or twice a week, here are some tips to keep your hair in top shape:
- Use a Gentle Shampoo: Look for sulfate-free or moisturizing formulas that won’t strip your hair of its natural oils.
- Condition Regularly: A good conditioner can replenish moisture and protect against damage.
- Limit Heat Styling: Overusing heat tools like flat irons and blow dryers can weaken hair.
- Protect Against Environmental Damage: Wear a hat or use a UV-protectant spray to shield your hair from sun damage.
- Eat a Balanced Diet: Foods rich in vitamins and minerals, like biotin and omega-3s, contribute to hair health.
Think of your hair as a prized plant—it needs the right mix of water, nutrients, and care to thrive.
Conclusion: Striking the Perfect Hair Care Routine
The “right” amount of hair washing varies from person to person. While washing twice a day might be overkill for some, it could feel necessary for others based on their lifestyle or hair type. The key is finding a routine that works for your unique needs without overloading your scalp or strands.
If you’re concerned about a loved one’s habits (like your mother-in-law’s double-daily washes), approach the conversation with curiosity and kindness rather than criticism. After all, hair care isn’t one-size-fits-all—it’s about finding balance and keeping those locks looking and feeling their best.
My wife had been marking tally counts on her hands — when I discovered what she was tracking, I turned pale

When I noticed my wife drawing strange tally marks on her hand, I shrugged it off as a quirky habit. But as those marks multiplied and her answers remained cryptic, I realized something much darker was lurking beneath the surface of our seemingly happy marriage.
“Married life is great, right?” I would say to my friends when they asked. And for the most part, it was. We’d only been married for a few months, and I was still getting used to being a husband. My wife, Sarah, was always so organized, so thoughtful. She had a way of making everything seem effortless.
But then, something changed. I started noticing a strange habit of hers. One day, she pulled a pen out of her purse and made a small tally mark on the back of her hand. I didn’t think much of it at first.
“Did you just mark your hand?” I asked, raising an eyebrow.
She smiled and shrugged. “Just a reminder.”
“A reminder for what?” I laughed, thinking it was a joke. But she didn’t answer. She just changed the subject.
Over the next few weeks, she did it more and more. Some days, there’d be only one or two marks. Other days, five or more. Then there’d be days with nothing at all. It seemed random, but it bothered me. What was she keeping track of?
The more I noticed, the more I started to worry. It was like she was keeping a secret from me, and that secret was slowly eating away at our happiness.
One night, I couldn’t hold it in any longer.
“Sarah, what’s with the tally marks?” I asked as we were getting ready for bed. “You do it all the time now.”
She glanced at the marks on her hand, then looked at me with that same mysterious smile. “It helps me remember things, that’s all.”
“Remember what?” I pressed.
“It’s just… things,” she said, brushing me off like it was nothing. “Don’t worry about it.”
But I did worry. A lot. I started paying closer attention. She’d mark her hand after dinner. After we argued. After we watched a movie. There was no pattern I could see.
One evening, I counted the marks on her hand: seven. That night, I watched as she transferred them into a small notebook by her bedside table. She didn’t know I was watching.
I decided to check her notebook the next morning. I waited until she was in the shower, then flipped through the pages. Each page had rows and rows of tally marks. I counted them—68 in total.
I sat on the bed, staring at the notebook in my hands. What did this number mean? What was she counting?
I tried asking her again a few days later.
“Sarah, please tell me what those marks are for. It’s driving me crazy.”
She sighed, clearly annoyed. “I told you. It’s just something I do. It helps me remember.”
“That doesn’t make any sense!” I snapped. “What are you remembering? Are you keeping track of something? Someone?”
“Just drop it, okay?” she said, her voice sharp. She looked at me, her eyes pleading. “Please, just let it go.”
But I couldn’t let it go. The marks started to feel like a wall between us. Every time I saw her make a new one, it was like she was putting up another brick, shutting me out.
I became obsessed with the number 68. What was so important about it? I noticed I was being more careful around her, almost like I was afraid to give her a reason to add another mark. But then the marks would still appear, no matter what I did.
One night, after another tense conversation, I watched her add four new marks to her hand. I needed to know what was happening. I needed to figure this out before it drove me mad. But I had no idea how to get the truth out of her. And that scared me more than anything.
I couldn’t shake the feeling that our entire marriage was on the line, and I was helpless to stop whatever was happening between us. I left for several days to see if it changed anything. Well, the tally count has increased to 78 by the time I returned.
The obsession with Sarah’s tally marks was eating me alive. I needed a break from it, but everywhere I looked, I saw her hand with those little black lines, like they were taunting me. So, when Sarah suggested we visit her mother, I thought it would be a good distraction.
Her mother, Diane, and her fifth husband, Jake, lived in a cozy house in the suburbs. It was a typical Saturday afternoon visit: tea, cookies, and small talk. Sarah and her mom were in the kitchen, chatting and laughing. I excused myself to use the bathroom.
As I passed by the guest bedroom, something caught my eye. There, on the nightstand, was a notebook. It looked just like the one Sarah kept by her bed. I hesitated, but curiosity got the better of me. I stepped inside, glancing over my shoulder to make sure no one was watching.
I opened the notebook, my hands trembling. Inside, there were pages filled with tally marks, just like Sarah’s. But there was more. Next to the marks were labels: “interrupting,” “raising voice,” “forgetting to call.” Each tally had a label, like it was keeping track of mistakes.
“What the hell is this?” I muttered under my breath.
I felt a chill run down my spine. Was this some kind of family tradition? Was Sarah’s mom counting her own mistakes? Were they both holding themselves to these impossible standards?
I closed the notebook and returned to the living room, trying to act normal, but my mind was spinning. Sarah noticed my unease.
“You okay?” she asked, concern in her eyes.
“Yeah, I’m fine,” I lied. “Just thinking about work.”
We stayed for another hour, but I was barely present. My thoughts kept drifting back to that.
On the drive home, I couldn’t hold it in anymore.
“Sarah, I need to ask you something,” I said, gripping the steering wheel.
She looked at me, puzzled. “What’s up?”
“I saw your mom’s notebook today. It looked a lot like yours. Is this something you both do? Are you counting your mistakes? You don’t have to be perfect, you know. You don’t need to keep track of every little thing.”
There was a moment of silence, then she let out a bitter laugh.
“You think I’m counting my mistakes?”
“Well, yeah,” I said, relieved she was finally opening up. “You shouldn’t be so hard on yourself. It’s okay to mess up sometimes.”
She shook her head, staring out the window. “I’m not counting my mistakes, Jack. I’m counting yours.”
The words hit me like a punch in the gut. “What?”
“Every time you break one of your vows, I make a mark,” she said quietly. “When you interrupt me, when you don’t listen, when you say you’ll do something and don’t. I’ve been keeping track since our wedding.”
On our wedding day, I promised Sarah the world in my vows. I vowed never to lie, to always listen without interrupting, and to be there every time she needed me, no matter what. It was a long list of grand, heartfelt promises that sounded perfect in the moment, but looking back, they were almost impossible to keep.
I felt the blood drain from my face. “You’re counting my mistakes? Why?”
“Because I want to know when I’ve had enough,” she said, her voice breaking. “When you reach 1,000 marks, I’m leaving.”
I pulled the car over, my heart pounding. “You’re going to leave me? For breaking some stupid promises?”
“They’re not stupid promises,” she snapped. “They’re our wedding vows, Jack. You made them to me, and you’ve broken every single one.”
I stared at her, stunned. How had we gotten here? How had I missed this? I’d thought she was being hard on herself, but I was the one who’d been careless, dismissive. I wanted to be angry, but I couldn’t. I was too shocked, too hurt.
When we got home, I couldn’t sleep. I called Diane, desperate for answers.
“Sarah told me what she’s doing,” I said. “Why didn’t you stop her?”
Diane sighed. “I did the same thing with my past husbands. I thought it would help, but it just drove us apart. It ruined my marriages.”
“Then why let her—”
“I tried to tell her,” she interrupted gently. “But she needs to see it for herself. I count good days now, Jack. Good things my husband does. It changed everything.”
I hung up, feeling more lost than ever. I could only hope that my mother-in-law’s words fell on fertile ground.
That evening, Sarah came home with tears in her eyes. “I’m so sorry,” she whispered, wrapping her arms around me. “I didn’t realize how much this was hurting us.”
I held her close, feeling a mix of relief and hope. “Let’s forget the tally marks,” I said softly. “Let’s start fresh.”
The next day, I bought a new notebook—one for us to fill with good memories and happy moments. We made our first entry that night, writing about a quiet dinner we shared, laughing and talking like we hadn’t in months.
As we moved forward, the notebook became a symbol of our promise to focus on the positives and grow together. The tally marks were gone, replaced by stories of joy, love, and gratitude. We were finally on the same page, and it felt like the beginning of something beautiful.
