Hair advice for fine, low density, low porosity, 2B-2C hair.

Hello All. I am a 35 (F) with shoulder length fine, low density, low porosity (holds onto water), 2B-2C hair. Once or twice a year ill dye my roots. I am seeking advice on how to better care and nurture my hair after 8 years of beaded weft style extension use. I do believe I took the best care of my hair during this time. But I decided to try and take a break.

I do have the lower side of iron levels, with a family history of thyroid issues (have tested but I'm "within normal range"). I would be willing to take supplements like iron, vit D.

I'm looking for advice/suggestions on how to sustain the length, and create strength. I don't expect my hair to get thicker, but I would like to make my hair stronger. I'm looking for product, supplement, hair styling recommendations.

At this time I wash twice a week, and maybe every 5 washes(ish) I use a clarifying shampoo bar. I add the balm and mouse after and let air dry I do brush my hair with the products.

Ok community let me know what you think. I'll answer as much as I can! Thank you for your support on my journey.
