Today, colour plays a central role in the world of hairstyling. In the past, hair dye was just for covering grey hair. Now, colour expresses and shapes who we are. The positive vibes of colour are influencing people of all ages and genders worldwide.

Current trends are pushing towards warm and natural nuances, but in every mood, even the boldest ones, colouring remains the most popular professional treatment in salons.

Now you know it too: to achieve the colour result you want, hair drying is a crucial step.

With the UNIQUE hairdryers, VALERA designers and engineers have developed 3 different motorisations and 9 different temperature/air output speed combinations that:

• offer 'tailor-made' performance for each hair type

• ensure the health and beauty of hair

• protect and enhance every colour tone.

The heat emitted by the hairdryer has a direct action on the hair fibre and on the scalp.

The heat of the hairdryer temporarily modifies the salt bridges that bind the hair fibres made up of proteins. Excessive heat can weaken the hair and cause it to break easily.

Heat dehydrates the hair because it expands the cuticles. When the cuticles open, the surface of the hair scatters light in several directions, creating a dull effect.

A heat jet that is too strong and too close can also damage the skin, which may itch, redden, become excessively dry or flaky.

Bubble hair effect: the heat of the hairdryer or straightener creates a temperature change on wet hair that causes water to evaporate very quickly, generating bubbles containing gases (sulphuric acid and carbon dioxide) that break down the structure of the hair and change it forever.
