I also recently went through an episode of telogen effluvium. I have nothing but <3 for everyone experiencing hair loss. It was extremely stressful, which is ironic since stress was the cause in the first place.

Anyway, I don't know what density you are now but I did start a "fine and thin" support thread... maybe there's something in there that may help your hair in terms of products/styling since you asked about newer products.

2s with Fine and Thin hair - support thread!

I hope you figure out a cure for your chronic TE. <3
fine - low/normal porosity - medium density - normal elasticity.

Currently using:
Cowash: Cure Care diluted with water 1:1
RO: Cure Care, V05 Kiwi Lime
Styler: UFD CM (old formula), FSG + CNPF
PT: IAgirl's gelatine

Experimenting with: no guar hydroxypropyltrimonium chloride, gelatin gel

Recent findings: my hair likes Cure Care diluted with water as a cowash; does NOT like guar h.c.!
