Is this something she gets from the doctor? Would you mind posting either a link to it online somewhere, or a picture of the ingredient list on the bottle? I'd like to see if it would be possible for you to make it at home and make it better/cheaper than wherever you're getting it now. I hate it when people make an inferior product and then charge an arm and a leg for it because they know people don't have a choice.
I wish my hair grew that long. It grows to my waist and that's it. I lost the gene pool lottery and got my grandmother's genes. She was wearing a wig already in her early 30's. Very thin, very fine, and only grows so long. I have to take care of what hair I have because I don't have much of it.
I have never had split ends that I recall. If I ever did, it was probably back in high school when I had a perm. I actually had thick hair back then.
If you're going to insist on using soap on your hair, at least you're using the ACV rinse. I still don't like the idea of having to fix what soap does to your hair every time you wash it, but I don't think I'm going to change your mind.
I will ask her for a bottle, or 2. These are OTC products. We can't afford to use the prescription ones the doctor recommends - way too expensive to play "Let's see if this one works".
I get the thick hair from my father and maternal Grandmother. She had long wavy red hair, red red. She didn't like women with long hair, said it pulled the face down. The splits ends happen when wear is done to the tip of the hair. It could be bad brushing habits, letting the hair hag down on clothing that is abrasive, or just because it has been there for 5 to 10 years. Mine was due to bad brushing habits, which I have corrected. The wear and tear from life is not much, as I wear it roped up on my head. This last batch went from 1" long all over to it's current length of 39" in 5 years. I can grow hair, and was donating it to Pantene for wigs.
Our water is on the acidic side, it will eat through copper pipes in 15 to 20 years. We have a water softener that takes out the worst of it, maybe that is why the bars don't eat up the hair.
