Oh my gosh...FINALLY! I'm a very health-conscious person, and there is no way I'm putting hormone-disrupting, cancer-causing aluminum chlorohydrate and chemicals (propylene glycol is basically anti-freeze) under my arms to Be absorbed into my lymph glands every day. Yuck! So, that means a natural deodorant. A high quality natural organic deodorant is safe, no type of anti-perspiring is. Thus began the loooong search for one that actually stops stinky pits! I've tried Tom's, Arm & Hammer, La Vanilla, Kiss My Face, Scmidt's, Primal Pit Paste, and all varieties that Chagrin Valley makes. Fail, fail, fail. The second best was Chagrin Valley. I like the Citrus Baking soda based one the best, because it actually kept me 90%+ stink-free. Unfortunately, nothing I tried could stop the horribly itchy, stingy, burning rash I continued to get over and over. And I never was happy with the slightly oily stains these cream and oil based deodorants left on my shirts. And they don't come out! Not good. I even tried two that Food Babe recommended-another brand of crystal spray and a cream/stick sage lime one (can't remember the brands). Fail again. I came to MUA looking to see if here was anything new to try in natural deodorants, and came across the stellar reviews for this one. Hmmmm. I was surprised, because I've seen it a million times, but wrote it off because I didn't have a good experience with the other crystal spray (it's in a small rectangular bottle with blue and green labeling). I HAVE tried the solid crystal stone and stick that Thai makes, and liked the results, but don't like the application because I was forever dropping or chipping the solid stick, and when it wears down it gets too small to stay in the container and you have to use it sideways so you don't poke yourself with the point. So about a week or two ago I bought a bottle of the Thai Crystal SPRAY after reading lots of the reviews here (gosh, I really do love and use MUA ALL THE TIME). Well. I'm gob-smacked. This stuff is all the raves say it is. I like the spray coverage as it seems to cover a wider area and I worry less about missing a spot. A quick blast of my blow dryer on high air and low heat dries it quickly so I can get dressed. No oily stains. No visible anything under my arms. No rash. No itching. No burning irritation. I still do sweat a bit, that's natural, good for your body, and needs to be expected when using anything natural deodorant-wise so that isn't a problem for me. The thing that just blows me away though is how totally stink-free I stay for much longer than ANY other anti-perspiring or deodorant I've EVER tried-natural or not! Wow. I'm impressed. In the space of the two weeks I've been using it, the weather has gone from the 50's and chilly to 98 and humid and it's worked great in all situations-sleeveless shirts, sweaters, sleeveless shirts under a light sweater, while sleeping, while working out...I'm just so jkoressed and I wish I had tried this so much sooner. I spray it on in the morning right after I dry off from my shower. Make SURE you have washed thoroughly under your arms because any trace of leftover stinky bacteria will affect your results. I like using a soap with teeny scrubby grains or body wash with a Salux. Super clean pits will give you the best results. The only time I smell a little stinky is when I work out the following morning after having applied the morning before, and hey, I think that's totally allowable and is not a problem for me. This stuff is my absolute HG deodorant now and I am DONE spending and wasting $ to try to find something that hits all the marks on what I want and what I need. This stuff is perfect. Two thumbs WAY up. So thankful for all the wonderful ladies who took the time to write a review on this fabulous product! Works so much better than I ever hoped it would! YAY!
