This is a solid pick when frizz and breakage are linked (hello, stressed ends). This shampoo for longer hair is infused with biotin, which helps prevent breakage by strengthening individual strands, minimizing surface frizz, and repairing hair internally. “When I notice my hair looking extra dry, I reach for this shampoo—it helps with damage, and the appearance of split ends,” says Gaskin. With consistent use, the result is smoother, stronger-feeling hair.
Best for Damaged Hair: Luseta Rosemary Mint Strengthening Shampoo
- What we love: Great value for the size, and stimulating ingredients
- What could improve: A little goes a long way with thin hair
Hair goes through a lot. Between heat styling, color treatments, over-washing, and even the drying winter air, your strands need strength to withstand it all. This biotin shampoo is a strong contender to hit “reset” on damaged hair, making repair the first step in your routine. Infused with biotin, rosemary leaf, and peppermint oil—plus nourishing argan oil—the Luseta Rosemary Mint Strengthening Shampoo does more than just cleanse. Biotin helps support keratin production for stronger strands, while rosemary and peppermint invigorate the scalp and boost circulation. Argan oil smooths, hydrates, and protects hair that’s been left brittle or dull.
Best Keratin Formula: Keranique Scalp Stimulating Shampoo
- What we love: Strengthens hair with keratin; sulfate-free and safe for color-treated hair; gentle enough for daily use; adds volume without weighing hair down
- What could improve: Requires regular use for visible improvement
Keratin is the structural protein that gives hair its strength, elasticity, and shine—but it can become depleted through heat styling, coloring, and environmental stress. Keranique’s Scalp Stimulating Shampoo stands out by delivering a proprietary Keratin Amino Complex designed to rebuild and reinforce damaged strands from root to tip. Combined with biotin and panthenol to nourish the scalp and promote follicle health, it helps restore resilience and fullness to fine or thinning hair. The sulfate-free formula cleanses without stripping, making it a smart daily choice for anyone seeking to repair keratin loss while building stronger, more vibrant hair.
Best Rosemary Shampoo: Mielle Organics Rosemary Mint Strengthening Shampoo
- What we love: Sulfate-free and safe for color-treated hair; subtle and invigorating scent; leaves hair noticeably stronger and shinier
- What could improve: Can feel drying if overused
Rosemary and mint bring that clean-scalp feeling, while coconut and babassu oils help keep strands from feeling stripped, though 4A to 4C hair types might need more moisture for detailing without heavy texture. This hair type can lean on the thin or fine side and will appreciate the gentle cleanse with soft results, and that’s even before you use conditioner. Coconut and babassu oils add moisture that’s noticeable but never greasy, making this a solid pick for natural hair that needs strength and softness in equal measure.

- What we love: Protein-packed formula that benefits all hair types; luxe scent that R+Co is known for

This shampoo gives that instant “more volume” payoff, which is especially satisfying when you’re noticing extra fallout. R+Co’s Thickening Shampoo gives strands that instant “oomph” factor. Infused with biotin, this shampoo helps nourish and strengthen from scalp to ends, helping to minimize the appearance of shedding over time. The formula’s light, gentle lather cleanses without stripping moisture, so your hair stays soft and touchable. Think of it as a reset button for tired, thinning hair in need of a little extra TLC. “This has become my go-to during cold, dry months when every gust of wind leaves my hair feeling brittle, leading to breakage,” says Glamour contributor Gaskin.
