Ok people, warning...this is probably going to be kind of long, but I will try to make my point as shortly as I can. Almost 59 yrs old, I have VERY long hair. I do not cut my hair, so it grew into a "v" shape, past my hind end. 😁 I also don't use anything put hairspray, and I keep it up in a bun. My hair is baby fine, easily tangles, and won't hold a curl. early this year, I had some systems, like every month going to the Dr, & gaining a lb or 2, and I couldn't understand why. Blood test showed that my right thyroid just decided it didn't want to work anymore. So, I got put on medication. Well, slowly, my systems started to get better, BUT...my hair was falling out. my hair brush, while washing my hair, WAY more than usual. Googled side effects on my medicine. One listing; hair loss. No, no, no! Had my husband take a picture of my hair, & when I saw several inches of the bottom, there wasn't much there. Moerie kept popping up on my phone, and I read several reviews. It went both ways, but I had to do something. So, I bit the bullet, and bought the shampoo, conditioner and the root spray. I broke down, and had my husband cut off all the thin hair at the bottom. Then I got out my sewing measuring tape, held the top of it on the crown of my hair, 26" long. Today is the first time I have used it. I don't use a hair dryer, unless I am in a hurry. First use, all I can say at this point is, my hair feels INCREDIBLY soft! I always let it dry some before I brush it, and it brushed out so easily. I NEVER thought that I would EVER spend that much $ for shampoo, but I am desperate. So.....I am going to use what I have, faithfully, and am very hopeful that it makes a difference for my hair. Just a word of warning to you all.....IF you also take thyroid medication, DO NOT take the hair growth pills. I looked it up, and they will interfere with your medicine. I will write another review when my bottles are empty. Hopefully, it will be a great review!
