How Often Should I Wash My Hair? (The Answer Isn't What You Think)

REAL TALK: REAL HAIR  | By Jackie Wilt |  Wild Soul Salon & Head Spa 

The honest answer is: it depends on your scalp, your hair type, the products you're using, and what your hair has been through. This article is going to walk through exactly what it depends on — so you can figure out what's true for you, instead of borrowing someone else's routine.

If there's one question I get asked more than almost anything else in the chair, it's this one. And almost every time, the person asking already has an answer in their head — usually something like "I'm trying to go as long as I can between washes" or "I've heard washing not washing is healthier."

I want to gently challenge that. Stretching out your wash days is not automatically the healthier choice. In fact, for a lot of people, it's quietly working against them.

Let's talk about why.

The Myth of "The Longer, The Better"

Somewhere along the way, going as long as possible without washing your hair became a badge of honor. Healthy for hair, dry shampoo for days, "training your roots" — there's a whole culture built around stretching wash days.

But here's what I see constantly in my chair: clients who are so focused on going long between washes that they've stopped paying attention to what their scalp and hair are actually telling them. They're not factoring in their scalp's needs, their specific hair type, the chemical services or processes their hair has been through, or how their current washing routine is actually affecting all of that.

Washing your hair isn't just about oil. It's about clarity, balance, and giving your scalp and hair what they need to function well. And that looks different for everyone.

Why Washing More Often Can Actually Heal Your Hair

This might be the most counterintuitive thing I tell clients, but I've seen it play out over and over again, with countless people in my chair: increasing wash frequency can dramatically improve hair health.

I'm talking about clients dealing with:

• Scalp flaking

• Hair thinning

• Hair growth issues

• Excessive shedding or fallout

• Chemically processed, dry, brittle ends

When someone comes to me with any of these concerns, one of the first things I look at is whether they're actually cleansing enough. Time and time again, when we increase wash frequency — and pair it with the right products and process — I watch these issues improve. Not worsen. Improve.

That's because so many of these problems aren't caused by washing too much. They're caused by not washing enough, or not washing the right way.

What I Actually Look At When Determining Wash Frequency

When a client sits down in my chair and asks me how often they should be washing their hair, I'm not giving them a generic answer. I'm evaluating a few specific things. Many ask is washing my hair too often making my hair fall out? I would argue its the opposite. Now I am not saying every person should increase the amount they wash their hair, nor am i saying washing everyday is the answer. I am saying evaluating your wash routine is important. Here is what i consider.

Your Scalp Comes First

This is always where I start. If your scalp is irritated, flaky, uncomfortable, or showing any signs of inflammation, that's a signal — and usually it means you need to be washing more often, not less.

Here's why this matters so much to me: your scalp is skin. It's an extension of the same skin that covers the rest of your body, and it deserves to be treated that way. When residue and bacteria are allowed to sit on the scalp for too long, it can continue to irritate the follicle. Over time, that irritation can contribute to real, lasting issues.

And yet, conditions like dandruff, seborrheic dermatitis, and scalp psoriasis get treated like things we should just cover up or ignore — especially because we don't always see them with our own eyes. We might notice a little flaking here and there and brush it off. But often, what looks like "just dandruff" is actually a sign that the scalp isn't being cleansed properly, not a sign that you're washing too much.

Look at the Roots, Midshaft, and Ends — Separately

This is something I think gets completely overlooked, and it's a big part of what makes this conversation so individual.

A really common scenario I see: a client has been growing out blonde highlights or another chemical service, and their ends are dry, brittle, and damaged, while their roots have grown in natural and virgin. What happens next? The roots get oily faster, while the ends stay dry and over-processed.

If we only think about "how often should I wash my hair" as one single answer for your whole head, we miss this completely. The real question becomes: what does the washing process need to do for each zone of your hair? We need an approach that addresses oil buildup at the scalp without stripping moisture from already-compromised ends.

Your Hair Type Changes Everything

Hair type plays a huge role here, and it's one I want to spend real time on. The American Academy of Dermatology recommends basing your wash frequency on how often your hair actually gets dirty or oily — and notes that this varies widely depending on hair type, texture, and scalp behavior. That tracks with everything I see in the chair.

If you have naturally dry or coarser hair, oil gets absorbed into the hair itself rather than sitting on top of it, which can change how often washing is truly needed.

Neither of these is "better" or "worse." They're just different, and your routine should reflect that difference. If your hair is fine its the opposite, If your ends are chemically treated it can appear like course hair and create fear around washing. All that oil needs to be take care of.

Are You Using the Right Products for Your Roots and Ends?

Here's something I talk to clients about constantly: your shampoo and conditioner might be working against you.

If you're using a shampoo that's more moisturizing — something like a cream-based or hydrating formula — but your root hair type doesn't need that extra moisture, it can actually cause buildup and oiliness, making it seem like you need to wash more often than you really would otherwise.

On the flip side, if you're using a clarifying or stripping shampoo on hair that's naturally dry, it might seem like your hair "doesn't need" to be washed as often — but really, your hair is just losing hydration. Remember, washing isn't only about cleansing. It's also about conditioning, and that part of the process matters just as much.

This is where I think a lot of people get stuck: they buy matching shampoo and conditioner sets — a color-treating shampoo with a color-treating conditioner, or a repair shampoo paired with a repair conditioner — because that's how products are marketed. But your roots and your ends often need completely different things, especially if you've had color services, are growing things out, or have any kind of imbalance between your scalp and your hair's mid-to-ends.

In my chair, I often recommend mixing it up. Choosing a cleanser that's right for your roots and a conditioner that's right for your ends, even if they're not from the same product line. It's about formulating for each zone of your hair, not just grabbing a matching set off the shelf.

Hygiene Is Personal — And That's Okay

Here's where I want to bring this all together, because I think this is the heart of it.

How often you should wash your hair isn't a number I can hand you that applies to everyone. Research on individual scalp microbiome variation shows that the microbial communities living on your scalp are unique to you — shaped by your physiology, your environment, and your lifestyle. What works for your friend, your sister, or whoever you follow online may genuinely not be right for you — and that's not a flaw, that's just biology.

Your scalp should be dictating your habits. Not a trend. Not someone else's routine. Not a number you read somewhere.

I also want to gently name something else, because I think it matters: there's often a psychological layer to all of this. Maybe you grew up with a belief — passed down, intentionally or not — that washing your hair often is "bad" or "damaging," or maybe the opposite, that you should be washing daily no matter what. Maybe self-care routines like hair washing have felt harder to maintain during periods of depression or overwhelm. These things are real, and they're worth acknowledging as you think through your own routine.

Evaluating how often you should wash your hair means being willing to look honestly at your scalp, your hair type, your hair's history, your current products, and yes — even some of the beliefs you've carried about hygiene for a long time.

What I'd Actually Tell You If You Were in My Chair

So let's say you're sitting in my chair right now and you ask me this exact question. Here's honestly how I'd walk you through it.

First, I want to know what you're used to. Your starting point matters, because where we go from here depends on it.

If Your Scalp Tends to Be Oily

If you're someone whose scalp gets oily and you're not washing very often, I'd suggest starting with washing every other day. Use a proper double cleanse, along with a shampoo and conditioner that actually match your hair type — not just whatever's in your shower right now.

Then, watch your scalp. If after a few days of washing every other day your scalp isn't oily, irritated, itchy, or flaking, you can start extending that out — one extra day at a time. See how your scalp responds before you stretch it further.

If You're Going Weeks Without Washing and Your Hair Is Dry and Brittle

This is a different starting point entirely. If this is you, I'd actually ask you to do the opposite — cut your current timeframe in half. If you're going 5+ days between washes, start washing and conditioning roughly twice as often.

And just as importantly, I'd want you treating your hair during this process. Think masks, deep conditioners, and additional hydrators every time you wash. Then pay attention: does your hair feel and look better? Less brittle, more manageable? If so, you might find a sustainable rhythm around washing twice a week.

There's an Experimental Piece to This — And That's Normal

Here's the truth: there's no single right answer, and there's no shame in needing to experiment a little. Sometimes the very products we're using, or the way we've been caring for our hair, are the reason we feel like we need to wash more or less often than we'd like.

If you want a general starting point to experiment with at home, I'd say start at every other day, and don't go longer than every two to three days — unless your scalp is giving you zero signals that anything needs to change.

But I'll always say this: getting guidance from a professional is going to get you to the right answer faster and more accurately than guessing on your own. Your scalp tells a story, and someone trained to read it can help you understand what it's actually saying. If you're in the Denver area book a headspa service and we can take a deep dive into your scalp health.

If you're not sure where to start, that's exactly the kind of thing we can work through together in the chair — because your hair has a story, and your wash routine should be written for that story, not someone else's.

Happy Hair Day.

6 Key Takeaways

• Your scalp should dictate your wash schedule — not a trend. Flaking, irritation, itchiness, and buildup are all signals that your scalp needs more frequent cleansing, not less.

• Stretching wash days isn't automatically healthier. For many people, going longer between washes is actually contributing to scalp issues, hair thinning, and dryness — not solving them.

• Your roots, midshaft, and ends are three different zones. Each one may need something different from your wash routine, especially if you have color-treated or chemically processed hair.

• Hair type matters. Fine hair tends to get oily faster; coarser or drier hair types absorb oil differently. Your wash frequency should reflect your hair's actual behavior, not a generic recommendation.

• Your products can be changing how often you think you need to wash. The wrong shampoo or conditioner for your hair type can create the appearance of needing to wash more or less often than you actually do.

• There's no universal number. Start with every other day, don't go longer than every two to three days unless your scalp shows no signs of imbalance, and adjust from there based on what your scalp is telling you.
