DHS zinc shampoo is another favorite on Amazon, and it includes one of the key ingredients that Dr. Mudgil recommends: zinc — specifically 2% pyrithione zinc — to heal, calm, and balance the scalp.

According to one reviewer: "I have been using this Zinc shampoo for only 2 months and even after the very first use, my dandruff was gone! I have not had to ‘check’ my shoulders once since I started using this product. It's amazing and I highly recommend this to anyone battling this annoying condition.”

More than 8,000 reviewers have given this Maple Holistics shampoo a perfect five-star rating, and it’s another great sulfate-free, therapeutic tea tree shampoo that helps ease flaking and irritation. It leaves hair feeling clean and moisturized simultaneously, and reviewers report that it helps with a range of other scalp issues like acne, seborrheic dermatitis, and rashes as well.

According to one reviewer: "I have suffered with allergies and skin sensitivities for most of my life. Most of the products I've tried are either good for you hair, or your scalp, but not both. I have long thick hair, which is oily at the scalp but can be dry at the ends. I Tried this product from Maple Holistics, and was blown away. Not only did it heal my skin irritation, but it made my hair really soft and shiny.”

It works best when I follow the instructions of leaving it on my scalp for a few minutes. I will be purchasing again in the future.”

This option combines antifungal tea tree and exfoliating salicylic acid for a powerful natural dandruff shampoo. It is paraben-free and non-comedogenic (though there are sulfates). However, a customer noted that it’s a good idea to shake the bottle before each use.

According to one reviewer: “My scalp feels so clean and I have absolutely no little specs and flakes anymore. After one use, this has completely eradicated all of the build up and junk on my scalp. My hair is also the softest it has been in my adult life, and looks fantastic. I even cried a little because I have been dealing with the ‘dandruff’ for years with no relief.”

This gentle shampoo option uses virgin hemp seed oil to seal in moisture and reduce flakes. And the manufacturer promises that it also strengthens strands and balances oil production. It's a great option for scalps that are sensitive to other dandruff remedies, like tea tree oil, SLS, and peppermint. It’s sulfate- and paraben-free, but does have a little fragrance included.

According to one reviewer: "THIS STUFF IS WORTH YOUR MONEY! I have spent thousands of dollars on scalp laser treatments, prescription topicals, and so much more, in efforts to get rid of my psoriasis when I have a flare up. I have been using this product for two years and it is the only thing that keeps my flare ups under control.”
