If that works for your hair, then stick with it! Not only do you save money, but it reduces clutter in the shower
I would LOVE to have one set of products that works consistently, but I've found that I have to switch up every couple of days or they stop altogether. It's like I have to "trick" my hair into thinking I'm continually changing products, when in reality I'm using my HGs 75% of the time.
Hopefully, your hair isn't as finicky as mine,
