Why Switch to Solid Shampoo Bars? The Complete Guide to Natural Hair Care
Making the switch to a plastic-free shampoo bar can feel like a big change at first but once you get the hang of it, it becomes one of those easy swaps that quietly makes a huge difference. If you’re looking to reduce bathroom waste (without sacrificing a proper lather), solid shampoo bars like Hair Blocks are a great place to start.
What Makes Shampoo Bars Better Than Bottled Shampoo?
Most liquid shampoos are largely made up of water, sold in a plastic bottle, and shipped around the country (or the world). Solid shampoo bars cut out a lot of that unnecessary packaging and transport weight because you’re buying a concentrated product in bar form, not “water in a bottle”.
A solid shampoo bar can last a surprisingly long time too for many people, it works out as the equivalent of multiple bottles of liquid shampoo, depending on how often you wash your hair and how you store the bar.
Hair Blocks are a brilliant example of this low-waste approach, arriving plastic-free, so you can make the swap without adding extra packaging to the bin.
About the Ingredients
Solid shampoo bars like Hair Blocks are designed to perform well as a shampoo. That means they’re made with a blend of ingredients — including plant oils and butters (like jojoba, hemp seed oil, cocoa butter and olive oil) as well as cosmetic cleansing and conditioning ingredients chosen to help the bar lather, cleanse and leave hair feeling soft.
So while they contain lots of naturally derived ingredients, they’re not necessarily a 100% “all-natural” formula.
How to Use a Solid Shampoo Bar (Tips for Best Results)
If you’re new to shampoo bars, here’s the easiest way to get a great wash:
-
Wet your hair thoroughly (it makes a big difference)
-
Rub the bar between your hands or glide it gently over hair to build lather
-
Massage the lather into your scalp
-
Rinse well
-
Let the bar dry between uses on a draining dish or rack
Top tip: keeping your bar dry between uses is the secret to making it last longer.
Some people find there’s a short “getting used to it” phase when they switch from liquid shampoo often it’s just about learning how much product you need and how best to lather for your hair type. Give it a couple of weeks and adjust as you go.
The Environmental Impact: It’s Not Just About the Bottle
Switching to a solid shampoo bar is one of the simplest low-waste swaps you can make. Shampoo bottles are one of the most common bathroom plastics — and even when recycling is available, not every bottle is recycled.
Choosing a bar helps reduce demand for plastic packaging and keeps your routine lighter and simpler. It’s one of those small changes that adds up fast, especially if it’s something you use week in, week out.
That “reduce the waste” mindset is exactly what we focus on at Earth Conscious — products that do the job properly, with as little environmental impact as possible.
Longevity and Value: How Long Does a Shampoo Bar Last?
How long a bar lasts depends on your hair length, how often you wash, and (most importantly) storage. As a general guide, many people find a bar lasts several weeks to a few months.
To get the most out of your shampoo bar:
-
Keep it dry between uses on a draining dish
-
Don’t leave it under the shower stream
-
If you like, cut it in half (handy for travel or trying different scents)
-
Pop it in your wash bag no liquid restrictions
Making the Switch: A More Plastic-Free Hair Routine
Once you’ve nailed the shampoo bar, you might want to build out the rest of your low-waste routine. A few easy next steps:
-
A solid conditioner bar (if you want to go fully bottle-free)
-
A reusable hair towel (less laundry, less drying time)
-
A simple storage tin or soap dish to keep bars dry and lasting longer
Every swap doesn’t have to be perfect — it just has to be doable.
