Hi Clara
Horse shampoo is for horses! I had a room mate once that swore it made her hair grow faster, but her hair never looked shiny and healthy to me. If you are looking for a good hair mask that will improve your condition, give you shine and brighten up your colour, here are a few suggestions:
REDKEN Color Extend Rich Defender Masque (R360)
MATRIX Color Care Therapie Masque (R185)
MATRIX Aqua Immersion Masque (R185)
Good luck with your search!
