Medicated Shampoos, Conditioners, Co-washes and Treatments For Itchy Scalp, Dry Scalp, Seborrheic Dermatitis (List)

Below is a list of medicated shampoos and conditioners for troubled scalps, sorted by product type and active ingredients. If you have dry scalp - see the end of this post for ideas (scroll to the end).

Many of these shampoos have herbal ingredients which can either soothe, irritate (or do absolutely nothing). Proteins may soothe a dry scalp, but can also be irritating for some people.

Essential oils like tea tree, rosemary, thyme, sage, (neem oil is going in small letters because it's so stinky) can be antifungal if used in adequate concentrations. But they can also cause sensitivity reactions or allergic reactions.

Sometimes detergents in dandruff shampoos can irritate already-irritated skin, however, there are some detergent-free options in this post and there are medicated conditioners at the bottom of the page for people whose skin or hair does not tolerate detergents. You can wash your hair and scalp with medicated conditioners.

Not everybody with itching will have flakes, not everybody with flakes will have itching. Some people get painful or itchy bumps instead - but the treatments are usually the same.
If you're not getting relief from any of these treatments, you may be reacting badly to fragrances, preservatives or some other ingredient in hair products. Or you may be dehydrating your scalp too much - see the final paragraph after the list.
And if you're trying lots of medicated shampoos and conditioners and topical treatments with no relief, please see a doctor or dermatologist if that is an option available to you. They can prescribe medications that may be more effective.

Lets talk about rotating treatments! If you are a frequent customer in the itchy or flaky or bumpy, scaling, patchy scalp department, there is a good chance you need to have 2 or 3 different medications that work on standby. Why? Because the fungus (Malasezzia) that is strongly implicated in scaling and flaking and itchy, unhappy scalps has many different variations, if not true sub-species, then like sub-species. For example, you might use a zinc pyrithione shampoo and it works now, but it may not work as well later on. It's possible that some fungi on your scalp that were causing the itch and inflammation were not affected by that medication - or they developed some resistance to it. Each medication has a slightly different method of "attacking" fungi and some methods work better on some fungi than others. So if that happens, you need a different medication to control these fungi the next time around. Some fungi will be controlled with zinc pyrithione, others will be controlled with ketoconazole or selenium sulfide. Sometimes sulfur will get the job done and sometimes salicylic acid (with or without sulfur) works best.

Some people need to rotate between different outbreaks or flare-ups. Some people need to rotate every time they wash their hair. It's not fun, but it helps.

If you need to use medicated shampoo often and your scalp is not oily, or all the shampooing dries skin and hair - consider using a medicated conditioner as a "shampoo" - it won't lather but it might provide some relief. If you have dry or curly hair - you might love it.

The Active Ingredients: Look for the listed concentration. If concentration is not listed on the bottle - be wary, but it might still work.

• Zinc pyrithione: Antifungal, may reduce scaling, may relieve inflammation. Effective at 1%, also effective at 0.5%, response may be slower than 1% (or not).
• Tar: Slows proliferation of skin cells. Skin cells proliferate too quickly with dandruff - so you end up with scaling and flaking. Effective as 0.5% active tar.
• Salicylic acid: Anti-scaling (remove scales and reduce flaking), can be anti-inflammatory and anti-septic. Effective at 1% to 1.5% and greater, sensitive skin may need 0.5% to avoid irritation. This exfoliates, so it may help with bumpy cysts if your scalp tolerates it.
• Selenium sulfide: Antifungal, effective at 1%
• Sulfur: Mild antifungal and antiseptic, anti-inflammatory, mild exfoliant. Effective at 2%
• Ketoconazole: Antifungal. Effective at 1%, 2% is the most-effective, prescription dose (non-prescription outside the USA).
• Tea tree oil: Anti-fungal, anti-septic when the concentration is adequate.
• Rosemary oil, thyme oil, cedar oils: Anti-fungal, anti-septic, may promote healing.
• Hydrocortisone: Inflammation is a critical part of the itchy-flaky scalp issue. Hydrocortisone reduces inflammation and relieves itching. Effective at 1%.
• Piroctone Olamine: Antifungal, Effective at 1% (unless I find otherwise)

Note: This is organized by active ingredients. Also indicated are: Sulfate-free, silicones. Sulfates ("sulfate detergents," a class of anionic detergents) and silicone emollients/detanglers are not necessarily bad for itchy or scaly scalps, but some people avoid them so I'm just trying to help you narrow the field. "Sulfate-free" shampoos are not necessarily milder or non-drying.

DRY SCALP? Got an especially dry or itchy scalp? Scalp needs soothing? 

• Wash only as often as you need to to keep ahead of itching. Just wetting and drying our skin creates irritation, so don't wash your hair/scalp unless it's dirty or looks bad or is getting more itchy when you don't wash it.
• Look for balanced shampoos and conditioners. "Balanced" in a shampoo means:

1. Look for more than 1 detergent (that makes it milder). For example, sodium lauryl sulfate + cocamidopropyl betaine or C14-16 Olefin sulfonate + cocamidopropyl betaine; any of these + decyl glucoside, or combined with Sodium Cocoyl Isethionate
2. You probably want some conditioning ingredients like cetrimonium chloride, polyquaternium ingredients, some emollients like plant oils or glycol distearate, sucrose cocoate, PEG-cocoate or silicones to soften skin make detergent less irritating.
3. You also want humectant ingredients which can act as anti-irritants that will help your scalp retain moisture and reduce irritation like polyquaternium-7, panthenol, sodium PCA, glycerin, hydroxypropyltrimonium honey, aloe, propanediol, glycine betaine, urea or allantoin.  These can be great for your hair too. 
4. In conditioners (if you put those on your scalp), look for the same things - aside from conditioning ingredients, look for those irritation-reducing humectants to round out protection for your scalp.
5. Try applying some oil (avocado, olive, jojoba...) to your scalp or a little fragrance-free skin lotion 10 minutes before you wash your hair. This softens the skin and protects it from the drying effects of washing. CAUTION: If you have a fungal component to your scalp troubles, oil can make it worse. Dry scalp can actually be a by-product of an "ecosystem imbalance."

If you live in a dry or windy area, protect your scalp from the wind because that can be so drying to skin - even a light scarf provides a good barrier.
