Dermaharmony 5% Sulfur 2% Salicylic Acid Shampoo Bar for Dandruff (4 oz)

It's now April of 2026 & it JUST NOW broke up into pieces. It will easily last me another month so I legit only spent $13 on shampoo for an entire year! I developed psoriasis on my scalp within the last couple years but it was carefully managed with multiple other products. However when I got pregnant, it got SO much worse, I'm assuming due to hormones. My scalp was itchy, red & raw, I often scratched myself until I bled. Then I saw this & thought "hey, if it doesn't work, it's only $13." When I first got it, I expected it to burn since I had open scratches on my scalp, but nope! Immediately got better, & i absolutely love that clean, almost medical fragrance free smell (not sulphuric at all, in my opinion). I only wash my hair once a week, & after several weeks of using it I accidentally used a different shampoo (Shea moisture) & the itchy flakiness IMMEDIATELY returned. I have not made that mistake since. Like I said I only wash my hair once per week because that's how my hair tolerates shampoo, but it is extremely clarifying so if you wash your hair everyday I would still only use this once a week (maybe every 2 weeks if you dont have any scalp issues). Will repurchase for as long as they're in business!!!!

I've been using this bar for a few weeks and it has really helped finally clear up my seborrheic dermatitis. I've been using a perscription 2% ketaconazole shampoo, T Sal salicylic acid shampoo from Neutrogena, and glycolic acid toner from The Ordinary but I still had little pimples/breakouts/flares. This bar cleared everything right up after using every other day alternating with the ketaconazole shampoo. It smells like peppermint (only slightly like sulfur when it is wet) and lathers really well. I like that it includes salicylic acid, because now I have one less product to use! It is drying, so pair it with conditioner. I also bought the bottle version for travel but that doesn't lather, smells like sulfur, and leaves a powder in your hair and the bottom of your shower/tub. Definitely go with this bar! It's a better cost per use too.

No more itching, no more flaking, no more scalp dryness. It's super affordable, takes up no space in my shower, is environmentally friendly and non-toxic. Seriously this is miracle-level good for some very persistent scalp issues! Tried all the other commercial products including Ketoconazole shampoo, this little bar is what finally worked.

Love this shampoo bar. I have dry scalp/eczema issues, and worried that a shampoo bar would not work as well as liquid T-Sal did. But the bar does control and soothe my scalp issues just as well as the liquid. It lathers better, in fact, really rich and satisfying. Smells good too, not overpowering but pleasant with the peppermint toning down any sulfury-ness. Love having soft, clean hair with no flakiness or guilt about putting more plastic into the ocean.

I was using 10% sulfur and 5% silicic acid play switched to some Dead Sea so with conditioners and try this after my scalp condition got better to reduce the drying effect

Excellent therapeutic shower soap. Long-lasting bar. No strong odor. Will purchase again.

I get nasty and painful bumps on my scalp that seem kind of like cysts. They can break open and ooze out liquid. I hate the bumps. I have tried special shampoos but this shampoo bar is my go to. I use it and leave it in for a few minutes before washing off. It seems to help with the bumps on my scalp, as if I use another shampoo for a few days, the bumps multiply and get worse. When I use this, there are fewer bumps and they are less severe. It has a little bit of a sulfur smell, but not as bad as some other sulfur shampoos I have used. I think it smells nice considering it has sulfur in it. I will keep using this.

I've fought dandruff since my preteen years. That was forty years ago. Lot of flakes since then. I've tried every product made. Whatever I used - after a few days it would stop working. The only thing that worked was rotating different active ingredients. Or shaving... This one... so far has been a game changer. Daily cleaning with this, combined with a conditioner, has fixed both my scalp and beard. Hope this review doesn't jinx it. Two things: first, for this (or any other) dandruff shampoo to work you need to use it right. Get your hair wet, rub this puck over (and add a little water as needed), and build a substantial lather. Now scrub, hard, thoroughly, with fingernails. Then let it sit for *at least* two minutes before rinsing. Second: this *will* strip everything from your hair. It will be dry, prone to tangles, breaking, and your skin will be dry - which means it will flake. A good moisturizing conditioner is a must. Here's hoping this continues to work.

It helps significantly in getting rid of dandruff from the very first day. ✨
