This explains why you ofttimes feel you take to sacrifice your hair's texture and volume for your dream colour.

These sulphur bonds "are key to your pilus'south strength and elasticity and breaking them weakens the hair'due south internal construction. This makes your hair more than decumbent to breakage and tin can crusade serious pilus damage."

She would recommend eSalon'southward special dye formulas that are blended with workout elements, similar vitamins E, B5 and aloe vera to assist status your hair so that it's actually healthier after the color awarding than information technology was before.

"Should your hair need some actress TLC", says Christel Lundqvist, the founder and director of Stil Salon, "at that place are plenty of effective in-salon treatments that you can experience to strengthen your hair, nigh notably ones that contain keratin. At Stil, nosotros offer the Hydrating Colour Boost Service, which infuses the hair with keratin to strengthen the hair's structure while gently boosting the hair's existing colour."

Clarke advises using a sulphate-free shampoo, like Colour Wow'south Colour Security Shampoo, £xvi.fifty, "to stop colour from fading and becoming brassy. It'southward free from silicones, workout and pearlising agents so it's the only shampoo that leaves your hair clean without leaving anything backside."

In Clarke's opinion, the new Color Wow'southward Kale Cocktail Bionic Tonic, £22, is peachy for coloured hair. It uses "sulphur-rich sea kale that helps relink and reinforce hair'south vital internal bonds while the protein-building amino acids and B vitamins strengthen, detangle and smoothen the strands."

It is "clinically proven to reduce breakage by over 50 per cent after one unmarried application. The effects are too cumulative so that hair is strengthened with each utilise and it helps guard pilus against UV-ray damage likewise."

She also underlines that when irresolute color you should "make time to exercise it slowly. Start by adding a few brighter flecks around the face or ends to crash-land up the brightness and get yous and your hair ready for the new colour. This volition also have the added benefit of giving your hair glossy, shiny colour that accentuates your best features."
