Solid Shampoo vs Liquid Shampoo: Pros and Cons

As my daughter flies out on her travels with my solid shampoo and conditioner in her suitcase, I thought I'd revisit why solid shampoos are a good idea for everyday use as well as on your travels.

Solid Shampoo vs Liquid Shampoo: Pros and Cons

Both solid and liquid shampoos cleanse the hair and scalp, but they differ in form, ingredients, environmental impact, and convenience. Here's a comparison to help you decide which might suit your needs best:


1. Form & Packaging

  • Solid Shampoo: Bar format, typically zero-waste or minimal recyclable packaging (often cardboard or paper).

  • Liquid Shampoo: Bottled in plastic or glass; more likely to contribute to plastic waste.

Advantage: Solid shampoo (eco-friendly, zero waste)


2. Ingredients & Water Content

  • Solid Shampoo: concentrated and water-free; contains fewer preservatives. Parabens, phthalates free.

  • Liquid Shampoo: Contains a large percentage of water (up to 80%); often includes stabilizers, thickeners, and preservatives.

Advantage: Solid shampoo (more concentrated, cleaner ingredients)


3. Longevity & Cost-Effectiveness

  • Solid Shampoo: Lasts longer (one bar can replace 2–3 bottles), cost-effective over time.

  • Liquid Shampoo: Used up more quickly due to overpouring or dilution.

Advantage: Solid shampoo (lasts longer per use)


4. Travel & Portability

  • Solid Shampoo: security-friendly, no liquid restrictions, no spillage risk.

  • Liquid Shampoo: Subject to liquid travel rules, bulky, prone to leaking.

Advantage: Solid shampoo (ideal for travel)


5. Ease of Use

  • Solid Shampoo: Requires a bit of a learning curve; you rub the bar on wet hair or hands to lather.

  • Liquid Shampoo: Very familiar and easy to use; quick to apply and rinse.

Advantage: Liquid shampoo (more user-friendly for beginners)


6. Customization & Variety

  • Solid Shampoo: Limited formulations but increasing variety.

  • Liquid Shampoo: Wider range of options for specific hair types, concerns (curly, color-treated, dandruff, etc.).

Advantage: Liquid shampoo (more targeted formulas—so far)

So, I'm sold, I think most of us can use a shampoo bar on our heads/hair like we use soap bars on the rest our body!
