When it comes to hair concerns, thinning continues to reign supreme as the most frustrating. Whether you’ve dealt with fine, limp hair your whole life or it crept up on you like a slow burn, tackling the obstacle is a tricky one. Some might think the secret to adding volume to thin hair is a professional blow dryer or expertly-trimmed haircut, but we’d disagree: It’s shampoo (and the occasional scalp massage).


But what works for one hair type might not work for another. So, we’ve hunted down the best thickening shampoos for different hair types and preferences. Some questions to keep in mind: Do you prefer Champagne prices or do you stick to a beer budget? Is your hair naturally curly or straight? Is your hair brittle by nature or breaking from color? Think about it and then, ahead, find the right formula for you.

Best Drugstore Thickening Shampoo

L'Oréal Paris Everstrong Sulfate-Free Thickening Shampoo

Fragile and thin hair doesn’t often play well with others — it’s too easily weighed down by some popular hair-care ingredients — but this sulfate-free shampoo might be its perfect match. Powered by rosemary leaf, the ingredient that’s long been touted as the secret to hair growth, this shampoo promises longer, healthier and fuller hair. It’s just an added bonus that it’s under $8.

Best Splurge Thickening Shampoo

Kérastase Bain Densité Shampoo

Keeping a style for more than a day is an uphill battle for you. It falls flat, and even after shelling out $40 for a professional blowout, your hair looks fine and lackluster after a few hours. This thickening shampoo levels the field — using hyaluronic acid, ceramides and gluco-peptide to strengthen hair and leave you with the kind of density you only thought hair-ad models owned. It’s these ingredients that surely make the slightly higher price tag worthwhile.

Best Thickening Shampoo for Brittle Hair

Biolage Full Density Shampoo for Thin Hair

Fine, thinning hair doesn’t exist in a vacuum; it’s often caused by a cocktail of concerns. This thickening shampoo starts with the scalp, tackling any follicle-clogging impurities (think: dirt, oil or dead skin cells) that might interrupt healthy hair growth. Then, it blasts your hair with biotin to strengthen hair and prevent breakage.

Best Thickening Shampoo for Volume

Kiehl’s Rice and Wheat Volumizing Shampoo

Thinning, lifeless hair needs proteins — and this volumizing shampoo has loads to offer. In addition to its lightweight proteins, this formula uses rice bran oil to cleanse the scalp of buildup that might be weighing it down, while giving hair that naturally full, thicker look.

Best Thickening Shampoo For Straight Hair

Shu Uemura Muroto Volume Shampoo

Naturally straight hair can struggle with maintaining that bouncy fullness, but achieving it doesn’t start at your blow-dry routine; it starts in the shower, with a volumizing shampoo. This paraben-free and silicone-free shampoo offers reprieve for your scalp, removing build-up that’s most likely leaving your hair limp and lifeless.

Best Sustainably-Minded Thickening Shampoo

Garnier Full and Plush Shampoo

This shampoo formula has one job: flood hair with strengthening proteins, so hair is healthier, stronger and more likely to look naturally full. But it doesn’t just prioritize making hair look thicker, it also uses sustainably-minded materials, like bottles that are made of 94% recycled plastic, and renewable energy to produce the formula that, like the name suggests, makes hair look plush.

Best Thickening Shampoo for Color-Treated Hair

JVN Embody Daily Volumizing Shampoo

Thinning hair, unfortunately, can be a side effect of long-term dye jobs, but you don’t have to sacrifice that pricey color for thick hair. This color-safe shampoo can help give you both. With a blend of caffeine (to support hair growth) and squalane (to help strengthen), you can expect both immediate and long-term benefits, including body and bounce.

Best Thickening Shampoo for Curly Hair

Melanin Haircare African Black Soap Reviving Shampoo

People with luscious thick hair have one secret: African black soap. According to the brand, this clarifying shampoo targets the scalp by promoting elasticity and creating a healthy environment for thicker, full hair to grow. Bett still, it makes your hair feel squeaky clean without stripping it.
