Since moving in, my girlfriend has been experiencing problems with her hair. Flat, dry, crackley, and brittle. She never had this problem at her previous apartment. When she gets her hair done at a salon, the results are noticably better. She's been to different salons with the same results.
I've had a water softener system installed to take care of minerals and PH. There is also a filter to take care of sediment. This system has not cured the hair problem.
What else can I do?
