Don't be afraid! - this wavy CGM die hard is a convert
I have thinning hair due to perimenopause. Then, I went through stress hair loss. Handfuls of hair were coming out, especially when I showered. I have fine 2b-2c wavy hair. I have used CGM for over a decade, which is how I discovered my curls. Before that it was straight. So, I was VERY hesitant to routinely use a shampoo with sulfate. But I figured WTH, I can wear my hair straight, at minimum throw it up in a loose bun or gater clip if I don't feel like styling it. Glad I went for it TL/DR: hair fall is now at normal levels and I still have my waves! I was shocked on multiple levels. First, after 2 uses, I have had a dramatic decrease in hair fall. At first I could feel the mint tingle on my scalp with the shampoo, conditioner and treatment. I didn't mind, felt like I knew it was working. 😂 I actually enjoyed the minty scalp. I felt refreshed after my shower and since I'm in perimenopause, the cooling sensation in the shower was greatly appreciated. After a month of use, the conditioner is still minty/menthol but only for the last minute or so before I rinse it out. The shampoo and treatment, not at all. Cleanse/Condition The shampoo definitely left my hair clean, it squeaked. I was worried since I could tell the cuticle was open. The shampoos I typically use have plenty of slip, this does not. Cue conditioner. My hair soaked it up. The cuticle closed back up to pre-shampoo standard when it was time to rinse it out. Did not expect that from the conditioner, especially as it's not as rich/thick as the ones my hair typically requires. Guess I shouldn't have based a book by it's cover, my hair had way more moisture than I anticipated. I will say that I used a ton of it, my hair just soaks it up. This is pretty standard for my hair. For every small bottle of shampoo, I typically need 3 standard size bottlesof conditioner. I did buy a second conditioner separately, after I noticed it was working. I still had a the same amount of hair fall on first use. Second use, still had hair fall but was dramatically less. After 1 week hair fall was back to normal! Added bonus, after I got out of the shower my hair was every bit as curly as it is when I follow CGM. Styling Now for styling. I plopped my hair, sometimes I use a dab of CK leave in to the ends or bottom 1/3 of my hair, but generally not. When it was midway down my back so, the ends tended to get dryer. Now that it's jaw length, haven't had to do that. Then I use the treatment spray. This definitely mentholated my scalp, for the first few days until it reduced to nothing. My scalp was pink for the first few hours the first time I used it, then never again. treatment does have some hold to it, which surprised me. I air dry my hair and the spray itself has some hold to it. I had to scrunch out my hair. Did the hold last all day, definitely not. I had to use a ton to get it through all of my hair. I don't like the way it made my hair feel after it dried. Somewhere between waxy and sticky and stiff. Now I focus it on my scalp. My hair has enough volume that I don't need the artificial thickening throughout, but it works well on my scalp. Plus I can then use my gel with zero issue.

Great Product!!
I am super happy with the product! My hair feels clean but not stripped of moisture. The conditioner works great and does not weigh my hair down or make it go flat. I’ve noticed after I blow dry my hair, it does feel fuller just from the product. I can’t wait to see how my hair feels after using the product for a longer period of time. Liked it so well I bought my sister in law some for Xmas.

Good product / CGM Convert
For reference, I have fine 3a hair. I was doing the curly girl method for several years and towards the end my scalp was feeling very unhealthy and I was losing a lot of hair (probably due to several factors) I tried lots of products and vitamins and would have to use multiple shampoos in one wash to get my scalp feeling clean. I’ve been using this set for about 3 months now. My hair looks and feels much healthier now. Most importantly my scalp feels clean and refreshed. I have not seen regrowth, but I have noticed I’m shedding less hair. Hopefully regrowth is coming. I have been using this conditioner plus my normal curly conditioner because I felt this one wasn’t super moisturizing. My curls still look good despite abandoning cgm. I would recommend this product and will keep using until I feel like my scalp/hair have fully regained health. If you’re on the fence make the switch!

Not a fix for my specific hair loss, but doesn't hurt anything!
I have been using Nioxin shampoo and conditioner for a few years. I hadn't been using it very consistently and noticed I was having a lot of hair fall recently, and decided to commit to it. I also decided it was time to see a dermatologist about my hair fall/loss. Turns out there is something else going on with me and this shampoo won't fix it - BUT it certainly won't hurt and my dermatologist didn't have anything against me continuing using it. But I will be addressing the actual medical reason for my hair loss. In the meantime, I'm continuing to use the shampoo and conditioner. I really love the smell and the way the product feels on my scalp. I have also been using the thickening foam that came with in the package. The foam is really interesting... I put it on while my hair is still damp and when it dries, it seems to sort of "glue" my hair strands together - makes it a little tough to comb through my hair at first. I can't decide if I like it or not. I'd say that it's more of a "volumizing" product - which is similar to other volumizing products I've used that raise the hair after blow drying. Overall -- I'll continue to buy this shampoo/conditioner because it's a great product and while it won't fix my hair loss, it will keep my scalp healthy. For anyone dealing with hair loss - I highly recommend contacting your Primary Care physician and your dermatologist and have them work together to evaluate and help diagnose you. I'm finally starting to see my hair stop falling out now that I know what the real problem is.

SO FAR SO GOOD - SHEDDING, THINNING SLOWED DOWN
I'm a senior and I guess because of age having some hair thinning. Neither Dermatologist nor Endocrinologist can really determine actual cause of hair thinning. I've tried several different hair loss shampoos etc. and nothing has stopped shedding etc. even Nutrafol did nothing to slow down shedding. Saw ad on internet about Nixion working well to stop shedding etc. so decided to try it. I just started to use the kit and don't know if I will ever have my hair back or close to what it used to be, but I did notice that shedding and thinning has slowed down a lot. After 3 months, hair should see some regrowth, we'll see, hope so. FYI: FORMULA 1 KIT.

Absolutely wonderful product
Absolutely love this shampoo and conditioner thickening kit. It smells amazing and after only using it for 30 days I'm starting to see slight changes in my hair, less shedding and more baby hairs coming in

I have tried many things to improve my thinning hair and Nixon is the only product I’ve had visible improvement with. Been using it for a year now and my hair is getting thicker and scalp is healthier with some new hair growth.
