Q&A

Ah! Pharmacy hair colourings! It’s an emotional issue that stirs heated debate between hairstylists and customers. Let’s settle the question once and for all: Does professional colouring perform better than colouring from the box?

RISK NO. 1: “UNIVERSAL” FORMULA

A “universal” formula may appear to be an advantage, but this isn’t always so! Whether hair is fine, thick, full‑bodied, natural or chemically treated, the mix will be the same for everyone. The manufacturer thereby ensures that it appears on all hair types.
Usually, the peroxide included in a “turnkey” formula is stronger than necessary. If you use too much, you risk damaging the hair fibre and getting dried-out, weakened and dull-looking hair.

As for professional colouring, it requires choosing the appropriate peroxide according to the desired colouring intensity. The formula will thus be custom-created based on current colouring, desired colour and hair type. Certain additives can even be included to neutralize or accentuate the highlights.

RISK NO. 2: UNREALISTIC EXPECTATIONS

There is something important to consider: the image on the packaging will likely not reflect the actual result. Using colouring from a box imposes some limitations with regard to possible results. This type of product can only make the hair two tones lighter or two tones darker.

Two persons may use the same pharmacy colouring and get completely different results. Underlying pigmentation, porosity, pre-colouring colour, grey hairs and other factors must all be taken into account.

RISK NO. 3: METALLIC SALTS

Affordable or natural henna-type colourings often contain metallic salts, a component of progressive colourings. With repeated applications, the hair will get darker and coarser and become more liable to react negatively to any other chemical treatment.

THE VERDICT

In conclusion, professional colouring offers more control over the results you get. It also ensures a safer process for the integrity of the hair fibre.

Of course, education and technical knowledge regarding hair products count for a lot when choosing a colouring. A professional can contribute expertise and advice tailored to your hair type, as well as to your reality. When in doubt, consult a specialist!
