When your hair is feeling damaged and fragile, washing it can seem a little scary. You’ll want a gentle hand, and also the Goldwell Dualsenses Bond Pro Fortifying Shampoo. This caring, strengthening shampoo has been formulated with red and brown algae to rebuild each strand from the inside out. Your hair will feel fresh and clean, for one, but also stronger and more resilient. Bonus feature: this whole line is especially for coloured hair, so you can expect your tint to last that little bit longer.
