If you’re switching to eco-friendly, zero-waste hair care, learning how to use a shampoo bar is the only step you really need. Shampoo bars are simple, travel-friendly, and designed to replace plastic bottles with a compact bar that lasts longer and reduces waste.
Below is a clear, beginner-friendly guide on how to use shampoo bar the right way - plus tips to get the best lather, avoid waxy buildup, and store your bar so it lasts.
What Is a Shampoo Bar?
A shampoo bar is a solid version of shampoo made to cleanse your scalp and hair - without the plastic bottle. Many people choose bars because they’re:
- Plastic-free
- Long-lasting
- Zero-waste / low-waste
- Great for travel
- Often made with gentler, thoughtfully chosen ingredients
At revivEARTH, we create eco-friendly shampoo bars and conditioner bars for people who want cleaner hair care and a cleaner planet.
How to Use a Shampoo Bar (Step-by-Step):
Here’s the easiest method (and the one most people love after the first wash):
1) Fully wet your hair
Shampoo bars work best when your hair is soaked. If your hair is thick, take an extra 10–15 seconds to ensure water reaches your scalp.
2) Wet the shampoo bar
Hold the bar under running water for a few seconds.
3) Create lather (two options)
Choose what feels easiest:
Option A: Lather in hands (best for beginners)
-
- Rub the bar between your palms until you get a creamy lather
- Apply the lather directly to your scalp
Option B: Glide bar on hair (best for quick showers)
-
- Gently swipe the bar 2–6 times over your scalp area (not the full hair length)
- Put the bar down and massage the scalp to build lather
4) Massage your scalp (most important step)
Use fingertips (not nails) and massage for 30–60 seconds. This lifts oil, sweat, and product buildup.
5) Rinse thoroughly
Rinse your scalp well. Let the foam run through your lengths—this is usually enough for the ends without over-drying.
Pro tip: If your hair is very oily or you use styling products, do a quick second cleanse. The second wash lathers faster.
Zero-waste storage tip: Use a soap dish with drainage or a bamboo tray so the bar dries completely.

Additional Information
How to Use a Conditioner Bar (Simple Guide)
Conditioner bars differ from shampoo bars in that they don’t foam as much. That’s normal.
Steps:
- Wet the conditioner bar
- Glide it over mid-lengths to ends (not usually the scalp)
- Use hands to distribute and detangle
- Let it sit 30–90 seconds
- Rinse (or lightly rinse for extra softness)
Tip: If you feel like it’s not “working,” you likely just need more water + more passes.
Common Shampoo Bar Questions
1. Why Does My Hair Feel Waxy After Using A Shampoo Bar?
This can happen during the transition from liquid shampoo, especially if you previously used silicone-heavy products. It can also be caused by hard water.
Fixes:
- Rinse longer
- Use a smaller amount on the scalp only
- Try an occasional apple cider vinegar rinse (diluted)
- Consider a clarifying wash every 1–2 weeks
2. How Long Does A Shampoo Bar Last?
Most bars last much longer than a bottle, depending on hair length, how often you wash, and how you store it. The #1 way to make it last: keep it dry between uses.
3. Can I Use A Shampoo Bar Everyday?
Yes - just choose a bar that matches your hair needs and avoid over-scrubbing your lengths. Many people wash 2–4 times per week, but everyone’s routine is different.
4. How Do You Use a Shampoo Bar on Long or Curly Hair?
- Focus on the scalp, not the ends
- Use lather-in-hands method to reduce tangles
- Rinse longer than you think you need
- Follow with a conditioner bar (especially for curls)
- Where to “Place” the Bar While Washing
A small change that makes a big difference: put the bar down between steps so it doesn’t melt away.
Zero-Waste Hair Care Tips That Make Bars Work Even Better
Want the smoothest switch possible? These tiny habits help a lot:
- Use a draining dish so your bars last longer.
- Keep bars away from direct shower spray when not in use.
- Store travel bars in a breathable container once they are dry.
- Use a microfiber towel or cotton tee to reduce frizz.
- Combine shampoo and conditioner bars to reduce plastic even more.
