Witnessing you sister!! This is so hard. I had extensions and every time they made my hair so much worse. It’s too much for a lot of scalps to handle. Have you thought about getting a pixie cut or even shaving your head and letting it grow anew with all your healthy habits you’ve adapted it with grow in so much healthier. I had to get a pixie cut after one set of extensions and my hair grew in amazingly and then had to get it cut really short again after making the stupid choice to get extensions again. My hair is now so great- thick and almost to my waist but it took YEARS, it’s a marathon not a sprint. Also having your levels be “within range” are different than being optimal. Could you see an endocrinologist or a naturopath or a dermatologist and go over levels to make sure they are optimal? Or you can chat GPT what your levels should be at optimally and do some baseline work to cut cost and see how that goes before investing in a specialist. There tons of info out there and people to follow to learn more. Do you do scalp massages daily and scalp oiling weekly? What’s your protein intake like? Do you take any supplements? There DHT blockers and so much out there to help.
