What is keratin and why is it important for hair?

In technical talk, keratin is a protein that is a major component in the make-up of hair and nails, as well as the outer layer of skin. So for healthy, beautiful hair, it’s important to keep the keratin in it strong    

Over time, exposure to the environment and chemical treatments or heat styling can damage the hair’s keratin structure and leave hair dry, dull, brittle and unmanageable. Protecting and fortifying the hair structure can help keep it healthy looking

Products designed for damaged hair often contain keratin in its ‘hydrolysed’ form, which is keratin broken down into small segments. When it’s in this form, it can easily bond to hair, and play a part in protecting and caring for it – which is why we’ve put it in our Dove Intensive Repair Treatment Mask

Some products contain a blend of amino acids (the building blocks of keratin) instead of keratin itself. They can better penetrate the hair and work from within. The Pro-Moisture complex in Dove Daily Moisture Shampoo and Conditioner is a blend of such amino acids, which penetrates the hair strands to moisturise deep inside   

You can also get products that contain actives, like alpha- hydroxyi acids, which can interact with the keratin in the hair and help repair its damaged structure. Our Nutri-Keratin Repair Actives are a patented blend of ingredients designed to penetrate deep inside the hair to repair and strengthen its keratin 

The Nutri-Keratin Repair Actives work continuously and gradually with every use to strengthen the keratin structure and make hair healthier in the long run. That is why we have put them in every shampoo and conditioner in Dove Nutritive Solutions
