Synthetic hair extensions: what impact on scalp health?

Synthetic hair extensions are a popular solution for a quick and easy style change. However, their impact on scalp health is an often overlooked topic. What precautions should be taken? Are there safer alternatives?

Risks associated with synthetic extensions

While synthetic extensions offer an attractive aesthetic appearance, they have several factors that can harm the scalp:

1. Chemical Compounds : Many synthetic fibers are treated with chemicals, including phthalates and flame retardants, which can cause allergic reactions and irritation.

2. Heat Release of Toxins : When these extensions are heated (with a flat iron or hair dryer), they can release small amounts of toxic substances into the air, increasing the risk of inhaling harmful products.

3. Friction and moisture build-up : Extensions can create excessive friction against the scalp, causing irritation and promoting the build-up of sweat and moisture. This creates an environment conducive to the growth of fungus and bacteria.

The consequences for the scalp

People wearing synthetic extensions may experience various discomforts such as:

• Itching and redness

• Appearance of pimples and irritations

• Sensitized scalp sensation

• Risk of contact dermatitis linked to chemical substances

In 2023, a study found the presence of pesticides and heavy metals, such as lead and cadmium, in some plastic extensions, which can have long-term health effects.

What are the safer alternatives?

Faced with these risks, several solutions exist to preserve the health of the scalp:

• Opt for plant fiber extensions : Some brands are innovating by offering fibers from plants such as banana trees, which are softer and more biodegradable.

• Favor natural hair extensions : Although more expensive, they present less risk of irritation and are more respectful of the skin if the treatment used does not involve substances of concern.

• Use looser ties : A tie that is too tight can create tension on the scalp and cause pain or hair loss.

• Maintain your scalp : Wash your hair regularly with gentle treatments to avoid the build-up of chemical residue and humidity.

While synthetic extensions offer an affordable and varied alternative in terms of hairstyles, it is essential to be aware of their potential effects on the health of the scalp. By favoring more respectful solutions and adopting good maintenance practices, we can combine aesthetics and hair well-being.
