My hair has deteriorated as I have aged and even with careful salon colouring, there are times when it has been so dry it looks like straw. I have used Olaplex before but not with such great results as the problem then was not as bad as it is now.
I think the process I am using is finally working - Olaplex 4, 5 and 8 (twice weekly) with 3 saved for a long treatment. I have also been using Keune Style thickening cream* on my dry hair (leave in no wash) in the morning to add cohesion to my style and this way I feel I am slowly restoring some control over my hair. *Living Proof 5 in 1 is also great on no wash dry hair as a finisher.
