Don't be afraid! - this wavy CGM die hard is a convert
By Cypress on Reviewed in the United States on February 8, 2025
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 itTL/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/ConditionThe 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.StylingNow 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.

Thickness dries out my hair
By Amazon Customer on Reviewed in the United States on February 25, 2025
I have color treated hair, so ordered the #4 trio. I really like both the shampoo and conditioner, because it leaves my hair shiney & manageable. I don't care for the leave in hair thickener though! Once I apply that particular product, my hair becomes dry and difficult to style. I'll have to give that item away to someone with shorter, oiler hair. Not sure if I'll reorder these products again, based on the price, but will decide once I've used for a month!
