This is me, too. I also use TN, but recently started using Yes to Carrots as my RO and then some more as a leave in, too. It helped for about a week, but now is back to straw. I also chelated, was better for about 2 days, now back to straw. Same with ACV. I've used every product and technique i can find with no real improvement. I sometimes wonder if it's even possible for me to have soft, moisturized hair. Maybe the softness and shininess I had pre CG was just due to silicones...I may take that route again. I'm so tired of looking/feeling like a scarecrow! Sorry to be such a downer, but let me know if you find something that works!

Silicones are anti humectants/ cuticle sealants/ occlusives, if you liked the effect of those maybe that indicates you need to look for comparable CG friendly ingredients. Vinegar also help the cuticle lay flat, the opposite of overusing humectants.
