The hidden dangers in your haircare products

While many of us trust the labels on our shampoos and conditioners, the reality is that some of the ingredients in these products may not live up to their promises. Worse, they could be doing long-term damage.

Kalan highlights four common ingredients to avoid:

1. Sulphates

Sulphates, like sodium lauryl sulphate (SLS), are powerful cleansers that help remove oil and dirt while creating a satisfying lather. Sulphates strip away your hair’s natural oils, leaving your scalp dry and your hair brittle.

This is especially problematic for people with sensitive skin, children, or textured hair, which needs extra moisture.

Look for sulphate-free shampoos, which are widely available and gentler on your scalp.

2. Parabens

Parabens act as preservatives, preventing mould and bacteria from growing in water-based products. Research suggests that parabens may disrupt hormones, potentially affecting hair growth and even your overall health.

Although more studies are needed, many consumers now avoid them as a precaution. Opt for products that are labelled “paraben-free.”

3. Alcohols

Alcohols are added to hair products for quick absorption or to improve texture. However, not all alcohols are created equal. The problem is that short-chain alcohols (like ethanol) can dry out your scalp and irritate sensitive skin.

Fatty alcohols (like cetyl alcohol), on the other hand, are hydrating and beneficial. Check the label carefully. Avoid harsh alcohols and choose products with moisturising alternatives.

4. Silicones

Why they’re used: Silicones coat the hair shaft, making it appear smoother and shinier and reducing frizz. The problem is that over time, silicones build up, blocking moisture from penetrating the hair. This can make your hair look dull and feel weighed down.

The solution: Use silicone-free products or clarifying shampoos to remove build-up. Anyone who uses haircare products is at some level of risk, but some groups are more vulnerable than others.

Women tend to use a wider variety of products, from shampoos and conditioners to serums, detanglers, and heat protectants.

Each product increases the likelihood of exposure to harmful chemicals.
