Having fine hair can mean applying a lot of product. From root-boosting powders to volumizing salt sprays, there are a plethora of hair products out there that promise to thicken your hair to its highest degree. While some of these products do their job and do it right, it’s important to lay the groundwork. In this case, going back to step one and finding the right shampoo to get your hair into perfect shape. When shopping for drugstore shampoo, some keywords to look out for are 'volume,' 'thick,' and 'boost.' These types of shampoos typically feature ingredients that won’t weigh hair down—an essential benefit for anyone with fine, flat hair.
From soothing aloe to refreshing mint to nourishing vitamin E, we’ve rounded up the best drugstore shampoos that do everything from plump your stands to repair damage.
Best Overall: Real Raw Shampoothie Biotin Boost Thick & Full Shampoo
With a base made up of 100% aloe juice and coconut water, this formula already knocks it out of the park. It definitely lives up to its name—within its powerful blend is nutrient-rich cold-pressed oils to nourish, biotin to strengthen, and plant proteins to thicken. Reviewers found that it not only smoothed down any frizz but didn’t cause hair to fall flat.
Best Budget: OGX Biotin & Collagen Extra Strength Shampoo
My favorite part about this shampoo is its lightweight consistency—second only to the results. After use, my hair always looks bouncier and feels cleaner. It’s all thanks to repairing vitamin B7 biotin and collagen, and body-adding wheat proteins. One reviewer raves that it helped reduce the number of her split ends.
Best for Frizzy Hair: L'Oreal Elvive Volume Filler Thickening Shampoo
This thickening shampoo creates fuller-feeling hair by targeting and penetrating your hair’s fiber from within. It essentially texturizes each strand, from root to tip, to enhance the look of volume. What’s even better? Your volume will last up to 24 hours.
Best for Straight Hair: TRESemme 24 Hour Body Healthy Volume Shampoo
Give your straight hair the body it deserves with a formula that will maintain its volume and shape throughout the day. A combo of Volume Control Complex and silk proteins promotes the appearance of thicker, fuller hair while it conditions and hydrates.
Best Detoxifying: Garnier Fructis Grow Strong Cooling Deep Clean Shampoo
Sometimes, we just want to feel our shampoo working. Mint and menthol—I can feel the aaahhhh already—work together to cool your scalp and cleanse it at the same time. It also features the Active Fruit Protein, a unique combo of vitamins, fruit extracts, and plant-derived extracts.
Best for Dandruff: Head & Shoulders Extra Volume Dandruff Shampoo
Eliminate every flake with this derm-approved and tried-and-true shampoo. This formula, however, has a twist—it features volume-boosting ingredients to take your hair from limp to lifted. Users also report that their scalps felt less itchy after continued use.
Best for Color-Treated Hair: Not Your Mother's Plump for Joy Thickening Shampoo
If you’re (not) a natural blond, like me, you know the right shampoo for you is one without hair-harming sulfates, parabens, and dyes. We already do a number with our color, we don’t need our shampoo exacerbating that. It’s pH-balanced, so while it gently cleanses your hair, it doesn’t strip it.
Best Volumizing: Odele Volumizing Shampoo
This salon-grade shampoo features mighty amino acids and nourishing amaranth to cleanse, moisturize, and volumize your hair. Users particularly love the plant-based and vegan formula. Plus, if you have a sensitive nose, you’ll be happy to find that the formula has no added synthetic fragrance.
Best Natural: ApotheCARE Essentials The Booster Volumizing Shampoo
With ingredients like burdock for detoxing, white willow for soothing, and seabuckthorn for revitalizing, this carefully-crafted volumizing shampoo utilizes natural properties to encourage thicker-looking hair. It helps to remove impurities, which in turn, creates a weightless, clean feel.
Best for Sensitive Scalps: Hairitage Outta My Hair Gentle Daily Shampoo
Reviewers love this moisture-rich shampoo for its gentle cleansing abilities. It’s mild enough to use every day, without removing your hair’s natural oils. One user notes that she has sensitive, eczema-prone skin, and this formula didn’t cause any flare-ups or irritation.
