What’s Inside Your Everyday Wash — And Why It Matters

When it comes to shampoo, conditioner, and body wash, most of us are just looking for one thing: something that feels good to use, and leaves us clean.

But what “clean” actually means — and how we get there — makes all the difference to your skin, scalp, and hair over time.

At POSTCARD, our liquid washes are plant-based, sulfate-free, and designed to cleanse without stripping your natural protective barrier. Here’s what that means — and why it matters.

What Are Sulfates (And Why Are They Used)?

Sulfates are a group of cleansing agents (surfactants) commonly found in shampoos and body washes — such as SLS (Sodium Lauryl Sulfate) and SLES (Sodium Laureth Sulfate).

They’re popular because they:

• create strong foam

• remove oil and dirt effectively

• give that “squeaky clean” feeling

However, they can also be too harsh for regular use, especially for sensitive skin or scalp.

Potential downsides of sulfates:

• strip natural oils

• disrupt the skin barrier

• cause dryness or irritation

• trigger excess oil production (as your skin compensates)

What About Silicones in Conditioners?

Silicones are often used in conditioners to give hair an instant smooth, shiny finish.

They work by coating the hair — which can feel great at first, but over time may:

• build up on the hair shaft

• weigh hair down

• prevent moisture from properly penetrating

This can lead to hair that feels smooth on the surface, but dry underneath.

How to Identify Silicones in Ingredient Lists

If you’ve ever looked at an ingredient list and wondered whether a product contains silicones, here’s a simple way to spot them.

Most silicones are easy to recognise because their names often end with:

• -cone (e.g. Dimethicone)
• -xane (e.g. Cyclopentasiloxane)
• -conol (e.g. Dimethiconol)

Our Approach: Gentle, Plant-Based Cleansing

Instead of harsh sulfates, we use a blend of milder, plant-derived surfactants that cleanse effectively while respecting your skin and scalp.

Key Ingredients We Use

🌿 Cocamidopropyl Betaine (from coconut)

A gentle cleanser that helps remove dirt and oil without stripping moisture.
It also boosts foam, giving you that familiar lather — just softer and less harsh.

🥥 Sodium Cocoyl Isethionate (from coconut)

A high-quality, sulfate-free cleanser known for its creamy, luxurious lather.
It cleans effectively while being significantly gentler than traditional sulfates.

🌾 Decyl Glucoside (from coconut + corn sugar)

One of the mildest surfactants available.
Biodegradable and skin-friendly, it provides a balanced, non-drying cleanse.

🧴 Sodium Lauroyl Lactylate (derived from lactic acid)

An effective emulsifier also used in food.
It helps bind oil and water, improving texture and delivering a smoother, more even cleanse.

Conditioning Without Build-Up

Cleansing is only part of the experience — how your hair and skin feel after matters just as much.

🌾 Guar Gum

A plant-based ingredient that smooths the hair cuticle, helping reduce frizz and improve manageability.

🧴 BTMS (Behentrimonium Methosulfate)

A plant-derived conditioning agent (despite the name, it’s not a harsh sulfate).
It detangles, softens, and conditions hair without heavy buildup.

Do Sulfate-Free Products Still Lather?

Yes — and this is one of the most common questions.

While sulfate-free formulas don’t create the same big, airy foam, they can still produce a rich, creamy lather when formulated well.

Our blends are designed to:

• feel satisfying to use

• spread easily through hair and skin

• cleanse thoroughly without dryness

What Does “Non-Stripping” Actually Mean?

A non-stripping formula cleanses while maintaining your skin’s natural oils and protective barrier.

Instead of that tight, squeaky feeling, you’ll notice:

• skin that feels soft and comfortable

• a scalp that feels balanced

• hair that feels clean but not dry or coated

Why This Matters for Daily Use

Your skin and scalp are part of a delicate ecosystem.
Over-cleansing can disrupt that balance, leading to long-term issues like dryness, sensitivity, or oil imbalance.

By using gentler, plant-based washes, you allow your body to:

• regulate itself more effectively

• retain natural hydration

• stay healthier over time

A Different Kind of Clean

Switching to sulfate-free products can feel different at first — especially if you’re used to strong foaming cleansers.

But over time, many people notice:

• less dryness

• fewer scalp issues

• softer, more manageable hair

• more balanced skin

It’s a quieter, more sustainable kind of clean — one that works with your body, not against it.

FAQs (Quick Answers)

Will my hair feel greasy without sulfates?
No — when formulated well, sulfate-free shampoos cleanse effectively without over-stripping.

Do natural cleansers still remove buildup?
Yes, but in a more balanced way that doesn’t disrupt your natural oils.
