The Beginner’s Guide to Switching to a Cleaner Hair Care Routine

By Ian Barnett, RN  |  ianbarnettrn.com

Let me ask you something.

When was the last time you actually read the label on your shampoo?

Most of us don’t. We grab what’s familiar, what smells good, or what was on sale. I did the same thing for years. It wasn’t until I started losing hair — and started researching why — that I realized how little I’d thought about what I was putting on my scalp every single day.

As a retired nurse, I know that what goes on your body matters. Your scalp absorbs what you put on it. And a lot of conventional hair products are packed with ingredients that, to put it plainly, aren’t doing you any favors.

If you’ve been curious about switching to a cleaner routine but don’t know where to start, this is for you. I’m going to walk you through what I learned — no overwhelm, no jargon, just a practical starting point.

Step 1: Understand What “Cleaner” Actually Means

“Clean hair care” is a term that gets thrown around a lot, and it can mean different things depending on who’s using it. For me, it comes down to this: products formulated without harsh chemicals that strip, irritate, or disrupt — and ideally, products built on ingredients that actually support hair and scalp health.

Some of the common culprits in conventional products worth knowing about:

• Sulfates (like sodium lauryl sulfate) — aggressive cleansers that can strip natural oils and irritate sensitive scalps
• Parabens — preservatives with a growing body of research questioning their long-term effects
• Silicones — create shine short-term but can build up on the scalp and block follicles over time

You don’t have to memorize a chemistry textbook. Just start paying attention to what’s in your products, and ask whether the ingredients are there to help your hair or just to make it feel good in the shower.

Step 2: Don’t Throw Everything Out at Once

This is the mistake I see people make most often. They decide to go clean, toss everything, buy a whole new shelf of products, and then feel overwhelmed — or disappointed when their hair goes through a transition period and they think it isn’t working.

Transition period is real. When your scalp has been used to sulfates stripping it daily, it’s been overproducing oil to compensate. When you switch to gentler products, it takes a few weeks to recalibrate. Your hair might feel different — not necessarily bad, just different — before it settles into its new normal.

My suggestion: start with your shampoo and conditioner. Those are what spend the most time on your scalp. Get comfortable with those, notice what changes, and then layer in other products from there.

Step 3: Look for Products Backed by More Than Marketing

This is where my nurse brain kicks in. I’m skeptical by training. The wellness industry is full of beautiful packaging and vague promises. What I look for is science behind the formulation — not just “natural” as a buzzword, but real intent behind the ingredients and evidence that they do what they claim.

When I was researching options for my own hair thinning, this is what drew me to Monat. Their approach isn’t “natural for the sake of natural.” It’s formulated with a specific purpose — to support scalp health and hair growth using ingredients that work together intentionally. That’s a different thing.

I didn’t just take the marketing at face value. I researched the ingredients, asked questions, and then tried it myself. Within two weeks, my hair stopped falling out the way it had been for months. That’s when I knew this was something worth sharing.

Step 4: Give It 30 Days Before You Judge

Hair has a growth cycle. Changes — good or bad — take time to show up. If you switch products and don’t see a difference in a week, that doesn’t mean it isn’t working. Give any new routine a genuine 30-day trial before deciding whether it’s working for you.

Keep it simple during that window: same products, consistent use, and pay attention. Is your scalp less irritated? Is your hair feeling different in texture? Are you seeing more or less in the shower drain? These are the signals that tell you whether something is actually making a difference.

Step 5: Ask Someone Who’s Done It

Reading labels and doing research is a great start, but there’s no substitute for talking to someone who has been through it. I spent months figuring this out on my own — trying things, researching, adjusting. I’d rather you skip that part.

Whether you’re dealing with thinning, dryness, scalp sensitivity, or you’re just done with conventional products that aren’t delivering, I’m happy to talk through what might be a good fit for your situation. I’m not a hair stylist. I’m a nurse who went through this personally and came out the other side with a routine that actually works.

That’s the offer. Take it or leave it.
