Hair needs a lot of attention if you want to maintain its health — so much that I find myself running out of hair products quickly, sometimes in just a few uses. Let’s just say, constantly buying new formulas isn’t exactly budget-friendly or great for the environment. That’s why I’m turning to shampoo bars to nourish my strands, minimize waste, and last longer. Luckily, Amazon is teeming with a ton of affordable options that are easy and convenient to use, so I picked out nine shampoo bars from $6 that promote hair growth, mend damage, and soften strands. 

Tackle thinning hair with the now-$11 Kitsch Rice Water Shampoo Bar that promotes softness and growth. The cleanser’s key ingredient, rice water, increases volume, while repairing breakage to encourage a denser appearance over time. One shopper who says that their strands see a “minimum of one inch [of growth] per month” wrote that their hair “grows so fast, it’s insane.”. Similarly, other reviewers shared that they notice “lots of new growth,” along with a “thicker, bouncier, and overall healthier” look.  

More than 12,000 shoppers swear by the Ethique Frizz Wrangler Shampoo Bar, calling it a “game changer for dry, itchy scalps,” as it provides instant relief. It nourishes brittle strands, controls frizz, and smooths flyaways thanks to hair-restoring cocoa butter and coconut. Plus, for just $15, this cleansing bar can last up to 80 washes.

As for an affordable option, stock up on Garnier’s Restoring Shampoo Bar for just $6. It removes dirt and buildup, while improving overall strand strength to reduce breakage and dryness. Not to mention, Drew Barrymore, who’s a brand ambassador, is a fan of its shampoo bars, keeping them “stacked” in her bathroom. Shoppers agree that it revived hair, with one reviewer saying that their strands are so “much softer,” feeling “like satin.” 

The Briogeo Be Gentle, Be Kind Cleansing Bar isn’t just nourishing for your hair, but for your face and body as well. This multitasker is made with colloidal oatmeal to deeply moisturize, along with soothing aloe vera and green tea extract to calm inflammation. This gentle formula is ideal for sensitive skin and scalps, with a reviewer vouching that it “doesn’t break [them] out, dry out [their] skin, or make [them] itch.” As for strands, shoppers rave that it improves hair texture for a “hydrated, soft, and voluminous” look."   

The Viori Hidden Waterfall Shampoo Bar is another cleanser formulated with rice water, but with the addition of shea butter and aloe vera, it increases hair’s thickness, softness, and shine. It’s also beneficial for damaged hair, as it builds strength and elasticity to prevent further breakage. Shoppers with thinning hair can’t get enough of this growth formula, raving that their tresses are “growing like wild” and are “so silky and full of body.”
