I have been a Biolage user for years now. The age I'm at now, my hair has more days where it appears to look damaged. It has a hard time holding moisture. So I was really pleased to find Biolage Age rejuvenating conditioner for strength and shine by Matrix. From the very first use my hair is responding completely different. it feels heavier and bouncier; not fly away. I did not have the frizzies after washing! There is a visible softness and shine that lasted for days. Thank you Matrix!
