Products for Dry/Damaged Hair

Just grow it out. If you need to style it with a flat iron, use Glampalm. The Healing Stone Technology in the ceramics protects the hair instead of burning it. It helped me when I damaged my hair.

If hair is too damaged because bleachings/dyings, there's almost nothing which can return it to the previous healthy condition... So yeah, only cutting it is the best solving of the problem [You must be registered and logged in to see this image.]
Anyway if the damage isn't too huge, you can restore it rather good with using good organic shampoos and conditioners, like on this site for example http://machohairstyles.com/best-shampoo-for-men/ [You must be registered and logged in to see this image.] Organic beauty products with oils are amazing, they helped me so greatly with the same problem! [You must be registered and logged in to see this image.]
Different masks can also be helpful, like from natural oils, aloe, eggs etc. [You must be registered and logged in to see this image.]
