Both of these are great products for dry, dull hair. I have used the shampoo & conditioner only once so far & I can see and feel a huge difference in my hair. I have remnants of a perm and color my hair regularly and it had become very dull & no longer shiny. The Biolage duo has added softness & shine already...can't wait to see what the results are after a few more uses! Highly recommended.
