Well I don't exactly have ur problem but similar. I had insanely think hair so when it thinned some in the front no one noticed but me. In fact people think I'm nuts. But I am currently having health issues myself. I have basically had a period since October...I was severe anemic. I had surgery to have a cyst removed and they ended up taking my whole ovary. So I had anesthesia then. I have been on vitamin d, biotin and a multivitamin. I am currently in the hospital just had a hysterectomy this morning. I too had gotten my hair cut in preparation. When my hair dresser cut it she said she was so surprised I hadn't really lost a lot...she thinks it's cause of my supplements. I also have been on a SheaMoisture kick. Not only are the moisturizing but they have protien. I did this thickening mask that they have 2 times this weekend. And I also used fall fight conditioner. I don't seem to get much out in the comb anymore. I'm gonna be off work for the next 6 weeks...so I'll be doing a lot of hair treatments.
Back on Cones,so now my routine is,wash with Deva No-Poo every other day or so. Occasionally use 365 sulfate free,maybe use low sulfate shampoo mixed with conditioner once every two weeks are longer. I condition with Aussie Moist or HEHH. I style with a little GF TN,and finish up with tons of GN Pure Clean Smoothing Cream. No frizz...slippy, happy hair.
