Coloring for a sensitive scalp

Tips and recommendations from a L’Oréal Professionnel expert

14 Aug 2025

Coloring your hair while maintaining scalp comfort is a task that just a few years ago seemed almost impossible. Today, thanks to advancements in professional formulas, it is entirely achievable. Daria Matveeva – L’Oréal Professionnel technologist and top colorist at Soho Beauty salon in Tashkent – shares how to choose gentle coloring for a sensitive scalp, which dye to use, and how to properly care for your hair after the procedure.

Why can the scalp react to coloring? 

Scalp sensitivity is quite common. The reasons can vary: individual characteristics, a tendency toward dryness, stress, climate change, or even a change in water. During coloring, discomfort often arises from ingredients responsible for opening the hair cuticle, such as ammonia.

Classic ammonia-based dyes can sometimes cause a tingling or tightening sensation on the scalp, especially if it is highly sensitive. But L’Oréal Professionnel has long had ammonia-free formulas that work gently and carefully,” notes Daria.

How do ammonia-free dyes differ from classic ones? 

Ammonia-free hair dyes do not contain ammonia. Instead, they use gentle components that allow pigment to penetrate the hair structure in other ways.

Can you expect a long-lasting color? 

Modern ammonia-free formulas handle various tasks successfully. “Such dyes are suitable for almost any hair type. It all depends on the goal: refreshing the color, adjusting the shade, or completely changing it. For a sensitive scalp, this is truly a soft and gentle solution,” the expert notes.

What is important to consider before coloring? 

Before coloring, especially if your scalp is prone to sensitivity, it’s important to follow safety protocols. “I always recommend doing a sensitivity test 48 hours before the procedure, especially if it’s your first time coloring or if you are changing the dye brand. It’s also best to postpone coloring if there are visible injuries on the scalp or a feeling of irritation and discomfort,” emphasizes Daria.

How to care for the hair after coloring? 

After the procedure, you should pay attention not only to preserving the color but also to the condition of your scalp. “I recommend using special lines for colored hair, such as Vitamino Color¹ and Metal Detox¹ from L’Oréal Professionnel. They gently cleanse the hair, prolong color longevity, and help maintain noticeable scalp comfort – which is especially important for those sensitive to external factors,” shares Daria.

Coloring and a sensitive scalp are entirely compatible – you just need to choose the right formula, follow the specialist’s advice, and organize proper aftercare. Modern ammonia-free dyes allow you to achieve an even, pure color while maintaining scalp comfort.

When it comes to coloring, you should always trust professionals and never skip sensitivity tests – this is the key to beautiful color and healthy-looking hair.
