Certain Dri Anti-Perspirant, Roll-On, Pack of 1, 1.2 oz

I bought Certain Dri Roll-On for my husband, and it worked so well that my brother decided to get it too based on our recommendation. Both of them have dealt with excessive underarm sweating, and this product made a noticeable difference. When used at night as directed, it keeps sweat under control for up to 48 hours. Pros: - Very effective for heavy sweaters. - Fragrance-free, so it doesn't interfere with cologne. - A little goes a long way. Cons: - Can cause irritation if applied after shaving. - Needs to be used at night and allowed to dry fully. Highly recommend for anyone dealing with hyperhidrosis or just wants reliable sweat protection!

So this stuff is amazing! I've suffered with sweaty armpits and embarrassment for 25+ years, so basically as soon as I hit puberty. I'd sweat even when I wasn't hot. Summer time was my nemesis and a night dancing was tricky finding the right top that wouldn't show sweat patches. I'd constantly be checking if I was damp or smelly. Often needing to change my top during the day. The doctor recommended an antiperspirant containing aluminium chloride and I went for this one. Well... it changed my life within days! Like the other reviews state the first few times causes discomfort, like a prickly stinging sensation and as this needs to be applied at night it can cause sleeping problems but I overcame this by putting it on just as I was falling asleep. I used it for 3 nights in a row, then every other night for 6 nights, then down to twice a week and now once a week! Thus stuff really works and if you can get past the unpleasant sensations you won't be disappointed. I'm now odour free and completely dry and confident!

This is my second time repurchasing this product. I apply it to my hands every night before sleep, and it’s made a huge difference in reducing sweat for pole fitness. Sweaty hands used to hold me back, but this has been a total game changer.

The only thing that works. I have tried a LOT of sweat blocks over the years since I sweat like crazy from my underarms. As a woman, this is especially difficult. I had to change my style completely and wasn't able to wear any tops other than tank tops to avoid embarrassment and I live in a country that usually doesn't have temperature above 10 degrees. This is a holy grail. It works. The side effects are worth it. Full disclosure, I got an an underarm burn from this a few times but nothing horrific. It also usually itches quite a bit. The first time I got a burn was when I applied it after shaving and then ignored the intense itching, didn't wash it off and woke up with red underams. Now I get burns every so often from this despite not repeating my mistake of shaving before use - honestly, I have no idea why it sometimes leaves me with chemical burns but as crazy as it sounds, the slight pain and redness are totally worth being able to wear whatever the heck I want and not having to worry about looking like I have run a marathon just from sitting at my desk. I have also noticed that it dries my underarms quite a bit, so I would advise on using a soothing lotion on days when you don't leave the house.

I used to use driclor but they made the bottle smaller and bumped the price up at the same time. Tried this as it has the same stuff in it. Sadly it does not work. Aluminium chloride hexahydrate on the label but sadly I don't think it has 15% inside. Maybe 1% if anything. Just pay the extra money and get the Driclor instead.

I am almost 40 and from about the age of 10, i can remember having quite extreme hyperhidrosis. I suffer with my under arms, hands and feet. Over the years I have learnt all the tricks to try and cover it up. Dark, or patterned loose clothes etc. I've hidden it from family, friends and partners. I've always been extremely embarrassed about it. I've tried many products over the years. I thought I'd give this a go, because if you're a true sufferer, you would try anything at any cost! I have been using this for approximately 2 weeks. I purchased the prescription strength because I know anything less simply wouldn't make any difference to me. The first night I used as directed. One or two strokes under each arm. Went to work the following day, sweating like mad as usual. No stinging. No burning. So I think I didn't perhaps use enough. So, second night, 2 or 3 strokes under each arm this time. Next day I felt slightly drier but still a little damp by midday. I was starting to think that it probably wouldn't work. By the third night I was feeling a little itchy under my arms, but I was actually quite relieved because it felt as if something was starting to happen. So same again, 2/3 strokes under each arm... I have been doing 3 nights on, then one off and although I have experienced the slight discomfort, slight burny/itchy feeling that others have described, I am definitely noticing an improvement. Not yet brave enough to go out in a grey top, but I'm going to try it next week. That will be the ultimate test for me. My arm pits have gone a little red from me itching, but it's a small price to pay if this continues to work. I'd say it's reduced my sweat by a very large percentage, not 100% as of yet but I will continue with how I'm using it and keep my fingers crossed! It's absolutely worth a go and I'd pay this every week if it worked! Just be sure to moisturise on the days you don't use it as it does help with the itching. Also I have noticed it has massively helped with the sweat smell, even when it's been very warm my arms haven't smelt sweaty at all. So I'm really pleased so far. Just to update, I've now been using this for nearly a month and I've been completely dry every single day. I'm still putting it on for 3 nights then off for one. That seems to be working for me. The stinging has subsided but it's still itching. However, I've worn a grey top, a pink top and a blue top to work and not a single sweat patch or hint of odour!! Another update. Now been using this 5 months and I'm down to using it once a week. Armpits are bone dry 95% of the time - tiny bit of sweating if I'm very anxious. No more itching at all and no stinging what so ever. I haven't applied for 5 days now and still bone dry. So I think once a week is probably enough now. I gradually reduced it over the months. Also I'm wearing anu colour but black every single day. Today I'm wearing a pale denim shirt 😃 try it !

I am not normally one for writing reviews, but in this case I really felt compelled to do so - for a while now I've been chopping and changing between all the generally available antiperspirants on the high street, researching the most effective ones, with almost nothing working to prevent the rivers of sweat I would often suffer under my armpits at work. Mitchum's did work for a little while, but that stuff was leaving horrible yellow stains on my shirts & after a few months of use I seemed to develop some kind of immunity & the sweat began to creep back in. It really sucks having to deal with horrible wet patches every day! Having resorted to things like under-shirts, jumpers or jackets as a cover up even on a hot day, I finally discovered Certain Dri via Amazon and I could not be happier with it so far. This stuff has really worked for me - not a drop of sweat under the arms after use, and a genuine 48 hour effectiveness. You have to follow the instructions properly per a lot of the other comments - apply just a couple of strokes under each armpit just before bed the night before, and make sure your pits are dry first. It's normal to have a mild itch (which is honestly all I would describe the sensation as; nowhere near as irritating as some of the descriptions I've seen here, but perhaps I'm just lucky in that regard.) I've been using this product about twice a week on average, still showering in the morning, applying a normal deodorant in the days & exercising etc as normal. It feels ridiculous to call a product like this lifechanging, but the impact on me has been awesome.

This seemed to work well the first week. But a few weeks later... I don't feel like I'm sweating but every night before bed, the evening after putting the other morning roll on in the morning and the night after putting this on before bed... I can smell slight BO on me and it's really annoying.
