SLS & SLES Explained: What parents should know about harsh cleansers

Flip over almost any shampoo, body wash, or face cleanser, and you’ll probably spot ingredients like SLS or SLES.

They’re common. They foam beautifully. They make products feel “deep cleansing.”

But here’s the problem: growing skin and scalps don’t always respond well to harsh cleansing.

This doesn’t mean every sulphate is “dangerous.” But when it comes to kids and teens, stronger isn’t always better. Let’s break down why SLS and SLES have become such controversial ingredients—and why gentler cleansing matters more than most people realise.

What Exactly Are SLS & SLES?

SLS (Sodium Lauryl Sulphate) and SLES (Sodium Laureth Sulphate) are cleansing agents commonly used in:

• shampoos

• body washes

• soaps

• face cleansers

Their job is simple:
to remove oil, sweat, dirt, and buildup.

They’re also what create that rich, satisfying foam many people associate with “clean.”

And that’s where the confusion begins.

The “Foam = Cleaner” Myth

Most people believe:
more foam = better cleansing.

But skin isn’t a greasy pan that needs to be stripped aggressively.

Sometimes, that squeaky-clean feeling after washing is actually your skin barrier being over-cleansed.

For kids and teens especially, this matters because their skin barriers are still developing.

Why Growing Skin Reacts Differently

Kids’ and teens’ skin behaves very differently from adult skin.

Their skin:

• loses moisture faster

• becomes irritated more easily

• reacts quicker to harsh cleansing

• struggles more with barrier disruption

Teen skin is already dealing with:

• hormonal oil changes

• sweat

• sports

• pollution

• puberty-related sensitivity

Adding overly harsh cleansing on top of that can leave skin stressed instead of balanced.

What Happens When Cleansing Becomes Too Harsh?

When products repeatedly strip away natural oils, skin starts struggling to stay balanced.

This can lead to:

• dryness

• itchy scalp

• frizz

• tight skin

• redness

• sensitivity

• flaky patches

• rebound oiliness

Ironically, over-cleansing can sometimes make teens feel oilier over time.

Why?

Because when skin gets stripped too aggressively, it often tries to compensate by producing even more oil.

The Scalp Suffers Too

Harsh sulphates don’t just affect skin—they can affect the scalp as well.

Many kids and teens experience:

• dry scalp after shampooing

• hair that feels rough quickly

• frizz after washing

• irritated scalp around the hairline

Parents often assume they need:

• stronger anti-dandruff products

• more shampoo

• more frequent washing

But sometimes the scalp simply needs gentler cleansing.

Are SLS & SLES “Bad” Ingredients?

This is where the internet gets dramatic.

SLS and SLES are not automatically toxic or banned ingredients. They’ve been widely used in cleansing products for years.

The real concern is how strong the cleansing experience becomes, especially for younger skin.

For growing kids and teens, repeated harsh cleansing can slowly weaken the skin barrier over time.

That’s why many modern formulations now focus on gentler cleansing systems instead of aggressive foaming.

Why Gentler Cleansing Matters More Today

Kids and teens today are exposed to:

• more frequent washing

• sports sweat

• pollution

• long outdoor hours

• stronger skincare trends

• over-cleansing habits online

Which means their skin barriers already deal with a lot daily.

Cleansing should remove dirt and sweat comfortably—not leave skin feeling stripped afterwards.

Healthy skin shouldn’t feel painfully dry right after a shower.

What Parents Should Actually Watch Out For

Instead of focusing only on labels, pay attention to how skin behaves after cleansing.

Signs a product may be too harsh:

• skin feels tight after washing

• scalp becomes itchy quickly

• hair feels rough immediately

• excessive dryness

• irritation around nose or hairline

• frequent “greasy but dry” feeling

Gentle cleansing should leave skin feeling comfortable—not stressed.

Why Tikitoro Focuses on Gentle Everyday Cleansing

Growing skin needs balance, not aggressive stripping.

Tikitoro formulations are designed to cleanse effectively while still respecting delicate skin and scalp barriers—because kids and teens need products that support their skin, not overwhelm it.

No harsh, stripped feeling.
No uncomfortable tightness.
Just gentle everyday care designed for growing skin.

The Tikitoro Takeaway

SLS and SLES became popular because they clean powerfully and foam beautifully.

But when it comes to kids and teens, stronger cleansing isn’t always smarter cleansing.

Because healthy skin isn’t supposed to feel stripped after every wash.
 It’s supposed to feel balanced, comfortable, and cared for.
