More lively after 1 use
Ok so I have to do this review bc it works! I've been battling hair thinning and ive tried a lot of products both topically and orally ...this is it...after one wash i saw my hair more lively and vibrant and shiny just after one use...not sure how it will hold up as far as making my hair thicker but I can already tell its making my hair stronger as well lively, so very impressed had to share So I had to come back and add pics bc it works and the pic says it all!! As u can see on the left is before I started using it and the second one is after only two times of using the shampoo and conditioner and I have used the mousse once which is in second pic! I washed my hair the same day these were taken and the left was from valentines day and the right one is from a day ago. As u can see the volume is undeniable!!! And let me also add that i tease my hair for volume purposes which I did one the left but I didnt even have to with this stuff, this is carzy! I have spent so much money on different products and to think I haven't tried this sooner, well im kicking myself in the butt!!

IT DELIVERS!
I’ve been using this shampoo for about six weeks, and the results are incredible. I’ve tried countless hair “systems” over the years (yes, even Mane and Tail), and this is the only one that has truly worked for me. I’ve added at least a full inch of length, and my hair is noticeably fuller. The bottles may look small, but a little goes a long way—use less than you think you need. For the results it delivers, it’s absolutely worth the price. I won’t be stopping this system anytime soon.

Conditioner does not last long
Issue: localized hair thinning due to hormonal changes post menopausal and tension provoked (tight pony tail on a daily basis). Length of hair to shoulders. In relation to the efficacy of these items for hair fall and regrowth…..my hair has slowed down and falls noticebly LESS but not regrowth is noted whatsoever. I am also doing Rogaine at the same time. I am on week 9th. The shampoo does live my hair a bit dry. I like the smell of fresh mint scent but I was disappointed about the size of the product. The shampoo bottle and the conditioner are the same size but it takes more conditioner than shampoo for my hair. I do not wash my hair daily but only 2x a week and since purchasing the products I have used the conditioner only 6 times and that is about all I got from it. The scalp serum is all right and more like a scalp tonic. All together I would give the shampoo and conditioner a 4 stars but I think the serum is not necessary. The product is very overpriced as a set together. After 2 uses of conditioner I only apply a quarter size to the scalp and use a keratin conditioner for the rest of my hair. The conditioner bottle will last you about 6 to 8 washes. I guess they figured that people have not much hair?? Yet the marketing ad for the product has a young woman with luscious, curly hair.

1 month in review
1 month trial, just bought my second bottle. (Review from a 21yr old mom, with post partum hair thinning/loss.) So I’m gonna be really honest with y'all when I say I saw one comment on tictok about this specific product from a middle aged mom and instantly got it. I’m 21, I have a one year old and I’ve noticed that my hair has basically stopped growing after I had him, along with the usual thinning and hair falling out you might expect after having a baby.. I wanted to stop bleaching anyways so I decided to use this along side it and let my natural hair grow out. (Have tried without this soap before for 6 months with maybe a 1/4th in of growth 😭 so I’m not trying to be bias hah) So far, I’ve noticed that my hair has went from frizzy and dry to really nice and soft just with the base soaps, I don’t have to use much personally because my hair is naturally pretty fine as is. I like the nice neutral smell of mint that the whole set has, and I love the feeling of coolness on my scalp after it’s nice lol. As far as hair froth my hair is actually growing again I’m shocked! I don’t have much of a reference on how unbelievably slow it was before but this is not even a month difference and it’s a huge difference for me. Another little thing is that I now have baby hairs all across my hair line that are growing pretty rapidly. Only small con for me is that it does make my forehead all red sometimes, or my scalp but the foaming stuff does say it’s happens and it’s not painful or anything so that’s the only thing! Over all this product has personally done me very well for post partum hair loss and over all hair health I love it. :)

Not sure it accomplishes everything
This does give a bit of thickness to thinning hair. It's a good shampoo and conditioner. I also use a leave in conditioner of another brand. I'm not sure that this actually makes your hair grow back, or makes your scalp fill in with new hair or anything. But it does make the strands thicker and your hair appear to be fuller, which is a plus in my book. Very pricey though. This is my attempt to avoid using Minoxidil, which makes me dizzy when I put it on my scalp. I'll know more in a few months I guess, which is what it takes no matter what you are using. I also use LED red lights, and Rosemary oil, but haven't seen any hair grow back yet. Will let you know way later.

It's working. I'm Very pleased.
I started using this product about 4 months ago. I've tried so many different shampoos for thinning hair that didn't work. This one is working, my hair was shedding so bad as I'm getting older. So much hair when I'd brush my hair. Hair was everywhere. Now there are only a few strands when I brush my hair. I also take a vitamin for hair thinning.

Saw Improvements
I like this hair combo product. The only complaint and the reason for 4 stars instead of 5 is that the foam, which is the main hair growth part, is not enough and doesn't last as long as the shampoo and conditioner do. I recommend doing a test before using it on your scalp. As it is mentioned in the product description and direction, the ingredients in the foam can cause a burning sensation and you skin can become red. For me it lasted about a few minutes the first time I used it and as I used it more the less the side effects got. The overall quality of my hair also increased. I just wished they had a bigger size foam.

Se nota un cabello mas grueso. La presentacion es pequeña, pero no necesitas mucho para limpiar bien el cabello. No hace que te salga mas cabello, pero ayuda a fortalecer el que tienes y darle mas cuerpo.
