This post is prompted by JenniferMD's post earlier about using the same product line...I noticed when I went thru my "beauty supply store" that I have several product lines(Motions, Alagio, Biolage, Farouk Silk Therapy, and Mizani) and I don't think that an entire line is necessary but some products really do work syneristically(ms)together....for example, the Mizani Bodifying Shampoo and Moisturefuse conditioner follow by a roller set with the ThermaElastic leave-in left my hair salon perfect...but I think that I just really like the Motions Oil Line(not the regular old school Motions, I hated that relaxer)...but for most store brands(Like Suave, Pantene or V05) I don't think it matters as much....any thoughts on this?
