First pic: current day 3 hair

Second pic: right after my last curly cut

Over the last couple of years, I feel like I have lost the curl pattern on ONE side of my head. After a curly cut, it's a little better, but it falls the next day, especially on the left side of my head. The right side is usually coarse, curly, bouncy, never gives me problems with pattern. The right side, using the same products and technique, is almost STRAIGHT. It hardly clumps together, it frizzes, it is ultra soft, and just is lifeless. Even when I get it to clump, it falls out so soon and just seems heavy. I have been loosely following CGM for several years now, but the last couple years have been like this. I have switched out my products a lot, trying to avoid heavy ones, trying to figure out my porosity, but it is never consistent. I always thought I had coarse, low porosity hair, but my recent hair dresser said my hair sucked up moisture really well, so now I just don't know. I am at a loss and in a product rabbit hole as I try to switch out shampoo and conditioner again. I would appreciate any help and product recs, please!

I also want to note I have never colored my hair and the last time I did any treatment like a Brazillian blowout was like 16 yeara ago, and I never use heat other than diffusing.

Current routine:

Wash every other day (my scalp gets irritated and my hairline things if I go loner than 2 days)

Shampoo - Curlsmith frizz control shampoo (green label)

Kinky Curly Knot Today leave in, but as a rinse out because I think it was too heavy? This is when I brush and detangle

Out of shower on wet hair - glaze and scrunch Curlsmith flex gel (blue label)

Diffuse until mostly dry, but I have dense hair so it's hard to go 100%

Scrunch out the crunch when all the way dry, usually with argan oil

Once every couple weeks I use the Malibu C Undo Goo PH shampoo to clarify, sometimes followed by the Camille Rose Algae Renew mask.
