I found that I have 3 reasons for my hair loss: My thyroid function, low estrogen after quitting my HRT( took for 10 years!) and finally, steroids and prednisone.
I was told by a dermatologist to use minoxidil (rogaine) but that I would have to use it continuously.
So I use hair care products that give the illusion of thicker, fuller hair—Nioxin shampoo, conditioner and scalp treatment. I use the #4 line for colored hair with progressed thinning. I feel it does make enough of a difference for me.
You can find it a your beauty salon or at ULTA beauty supply.
