Pros
- Does not strip curls
Cons
- Very low lather, so might not be best for buildup
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Methiopeptide, Rosemary leaf extract
Curly heads should gravitate toward hydrating shampoos and conditioners since the textured strands are more prone to dryness and breakage. Living Proof’s curl range keeps the ringlets extra juicy, with plenty of conditioning agents to help provide slip and softness, as well as peptides to strengthen the strands. Not to mention, the formula includes rosemary leaf extract—a natural ingredient renowned for its hair growing abilities.
Pros
- Mirrors a highly concentrated hair growth serum
Cons
- Pricey for a small bottle
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Karmatin, Red clover, Mung bean, Curcumin
This formula is brimming with hi-tech ingredients for healthy hair growth: There’s karmatin, a vegan keratin made from fermented silk protein to create a mirror image of the amino acids that naturally occur in hair; marula, baobab, and ximenia seed oils to provide moisture and nourish the strands; and red clover, mung bean, and curcumin to fortify the hair follicles and protect against inflammation.
Pros
- Great for gray hair or hair with highlights
Cons
- Very pigmented, so can stain
Considerations: Cruelty-free, Sulfate-free
Active ingredients: Hibiscus flower extract, Silk amino acids, Hydrolyzed silk protein
Silver strands can easily appear dull or brassy thanks to pollution, topicals, heat damage, and other stressors. “Gray hair grabs what’s in the atmosphere, so it can turn yellow very quickly,” says color and hair expert Christin Brown. That’s why many opt for a purple or blue shampoo to correct these subtle changes. dpHUE’s blond- and gray-enhancing shampoo not only contains purple pigments to neutralize brassy tones, but it also comes loaded with vegan silk proteins, amino acids, and hibiscus flower extract to repair and protect strands from environmental aggressors. Your hair will appear brighter, fuller, and most importantly, feel stronger over time.
Cons
- Contains essential oils, if you’re sensitive to those
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Ginseng root extract, Biotin, Maltodextrin
Your hair is made up of protein, but those amino acid chains can weaken over time, which can lead to breakage. That’s where bond-building ingredients like biotin come in: “We can’t recreate the exact protein that is in our hair [with topicals], but synthetic and naturally sourced proteins can repair and stand in place like a Band-Aid,” explains hairstylist Matt Newman about protein treatments for hair. That’s precisely why Briogeo includes biotin in their volumizing shampoo, as well as ginseng root extract to combat free radicals and maltodextrin—a starch-like substance that creates a film-like coating on the hair, which thickens the strands and gives the appearance of a fuller mane.
Pros
- Great for fine, color-treated hair that’s prone to dryness
Cons
- Not the best for thicker hair
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Green tea, Sage, Jojoba oil
Finding a wash that provides a deep clean without stripping the pigment off your strands can be difficult if you have color-treated hair. A color-safe shampoo is key, like this Pureology number: The lightweight jojoba-oil-infused lather won’t disrupt your gorgeous color, and it includes antioxidant-rich green tea extract to protect your strands and scalp, as well as sage to stimulate those hair follicles.
Pros
- Makes hair shiny and frizz-free without silicones
- Luxurious fragrance
Cons
- Contains essential oils
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Ceramides, Squalane, Hemi-squalane
No product can truly “repair” split ends, but JVN’s strengthening range comes pretty close: Ceramides mask the appearance of dry, brittle ends; aloe juice drenches the strands in hydration; and jojoba oil simultaneously conditions with every wash. The formula also swaps squalane and hemi-squalane for silicones—they provide a similar amount of slip and softness to the strands, but unlike silicones (which don’t really benefit the hair aside from aesthetics), they simultaneously deliver moisture and improve hair health over time.
Pros
- Addresses unique hair goals
Cons
- Questionnaire requires some basic knowledge about hair type & porosity
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Depends on custom formula
At the end of the day, hair thinning is personal: Shedding can happen for a number of reasons, which is why Prose offers a questionnaire to understand your specific hair type, texture, and length goals. From there, you’ll receive a curated selection of high-quality hair care products, including a sulfate-free fortifying shampoo. While ingredients may vary depending on your results, some common players include biotin to strengthen, silk proteins for repair, apple cider vinegar for shine, green tea water to protect, and peppermint extract to stimulate the scalp.

Pros
- Removes buildup without stripping the scalp
Cons
- Contains essential oils, if you’re sensitive to those
Considerations: Vegan, Cruelty-free, Sulfate-free
Active ingredients: Apple cider vinegar, Peppermint extract
Flakes and buildup can suffocate the hair follicles and eventually lead to shedding. If you’re dealing with dandruff, you might want to opt for a clarifying shampoo with apple cider vinegar. The antimicrobial, anti-yeast, and antifungal ingredient is a popular addition to many natural dandruff shampoos. When dandruff-causing bacteria don’t like the acidic environment, they tend to stop multiplying. “When used for short contact, such as in a shampoo, it is generally safe and well tolerated,” board-certified dermatologist Rachel Nazarian, M.D., previously shared with mbg. To keep it moisturizing, the formula also loops in Jamaican Black castor oil and shea butter, so your scalp won’t feel too tight or squeaky.
Best for buildup: Olaplex No. 4C Bond Maintenance Clarifying Shampoo

If you’re in need of a deep clean, you can’t go wrong with this Olaplex number.

Pros

Considerations: Vegan, Cruelty-free, Sulfate-free
