If your hair is getting thinner, the right shampoo can help your scalp stay healthy and make the hair you have look fuller. It’s worth being honest up front, though: no shampoo regrows hair the way minoxidil can.
So we picked shampoos that do something useful, from ketoconazole and caffeine formulas with some research behind them to cheap volumizers that make fine hair look thicker on day one. Most cost less than $20.
Best overall: Nizoral Anti-Dandruff Shampoo, because a healthy, flake-free scalp is the best starting point.
Best for instant volume: OGX Thick & Full + Biotin & Collagen, one of the cheapest picks here.

Shampoos with active ingredients
1. Nizoral Anti-Dandruff Shampoo (1% Ketoconazole)
Keep in mind: It can leave long hair feeling dry, so condition the lengths afterwards, and it isn’t meant for daily use.

Best for: People who want a caffeine shampoo · Price range: Mid-range (250 ml) Alpecin is the best-known caffeine shampoo. The idea is that caffeine reaches the hair roots during the 2 minutes you leave it on, and lab studies on hair follicles look promising. The evidence in real people is still limited, so think of it as a pleasant, energizing daily shampoo with a possible bonus rather than a treatment.Keep in mind: It costs more per ounce than most drugstore shampoos, and you have to leave it on for 2 minutes every time for it to make sense.
Check price on Amazon3. Nioxin System 2 Cleanser Shampoo
Keep in mind: It’s designed as step one of a three-step system, and buying the conditioner and scalp treatment too adds up quickly.

4. Mielle Rosemary Mint Strengthening Shampoo
Keep in mind: The mint scent is strong, and the research on rosemary is about the oil, not a shampoo you rinse straight off.
Check price on Amazon5. OGX Thick & Full + Biotin & Collagen Shampoo
Keep in mind: The fragrance is strong, and it can feel drying on very dry, curly or color-treated hair.

Best for: Thin, color-treated hair · Price range: Budget (8.5 oz) A sulfate-free shampoo that cleans gently, so it’s kind to colored hair. It contains rosemary and is made to make thin, fragile hair feel thicker and stronger. If you dye your hair and it’s starting to look see-through at the ends, this is a sensible, cheap swap.Keep in mind: Sulfate-free shampoos lather less, so it may not fully remove heavy product buildup without a second wash.

Best for: Hair loss from breakage · Price range: Budget (16 oz) A newer Dove shampoo aimed at hair that’s thinning because it breaks. It contains glycerin and zinc to care for the scalp and make hair stronger. It’s large, affordable and mild, so it’s an easy everyday choice for the whole household.Keep in mind: It’s new, with far fewer reviews than the others, and ‘hair loss’ on the label means breakage, not genetic thinning.
Check price on AmazonWhat a shampoo can and can’t do
- It can keep your scalp clean and calm, reduce breakage, and make hair look fuller for a day or two.
- It can’t reverse genetic hair loss on its own. For that, minoxidil is the best-proven option you can buy without a prescription.
- Leave it on. Active shampoos like Nizoral and Alpecin need a few minutes on the scalp to do anything.
- See a doctor if hair loss is sudden, patchy, or comes with pain or redness.
FAQ
Can shampoo cause hair loss?
Normal shampoo doesn’t. You’ll see hairs in the drain because you’re washing out hairs that had already shed. Harsh scrubbing and tight hairstyles can cause breakage, though.Is biotin shampoo worth it?
Biotin in a shampoo is rinsed off quickly, so it does little. Buy biotin shampoos for how they make your hair look and feel, not for growth.How often should I use Nizoral for thinning hair?
Two or three times a week is typical. Use a gentle shampoo on the other days.Which shampoo is best for female hair thinning?
Any of these work for women. If your hair is colored, start with the L’Oréal EverPure, and pair it with Nizoral if your scalp is itchy.Price ranges are a rough guide.
