### Best for Color-Treated Hair: ColorWow Anti-Hair Loss Shampoo
Price: $24 at Sephora
Why we love it:
I can’t count how many times I’ve gotten out of the shower only to realize my shampoo didn’t rinse out completely. Thankfully, this one is designed to wash away cleanly, leaving no residue that could weigh hair down or clog follicles—both of which can slow hair growth. Just a dime-sized amount is enough to give you frizz-free, shiny hair that people will notice.
Dermatologist Dr. Pooja Rambhia points out that the formula includes caffeine and niacinamide, which some studies suggest may boost scalp circulation. “It also has biotin and keratin proteins to strengthen existing hair,” she says. However, she notes that since shampoo has limited contact time with the scalp, its effectiveness for regrowth isn’t as strong as leave-in treatments.
Key Ingredients: Sodium methyl cocoyl taurate, sodium cocoyl glycinate
Size: 250 mL
Safe for color-treated hair: Yes
Scent: Unscented
Best for: All hair types
Cruelty-free: Yes

### Do Hair Growth Shampoos Work?
According to Dr. Hardik Doshi, hair restoration surgeon at Ample, results vary since hair loss has many causes. While some ingredients show promise, scientific evidence for major regrowth is limited.
—
Let me know if you’d like any further refinements!Hair loss can stem from various causes, and consulting a dermatologist or hair transplant surgeon can help identify the root issue and determine the best treatment for your specific needs. Treatment options may include specialized shampoos, medications, or surgical procedures.
Trichologist William Gaunitz notes, “Hair growth shampoos can be effective in certain cases, but they’re usually not the most powerful solution for regrowing hair.” These shampoos are often used alongside serums or medications that target the underlying cause of hair loss.
The reason? Shampoos alone don’t deeply affect the scalp unless there’s an issue like inflammation, excess oil, bacterial or fungal overgrowth, or parasites. Gaunitz adds, “If a shampoo contains active ingredients that address these problems, it can help improve hair growth.”
### How Does Hair Growth Shampoo Work?
According to Gaunitz, these shampoos promote a healthy scalp by reducing oil, bacteria, fungus, and inflammation. Many contain natural ingredients like saw palmetto, tea tree oil, and arnica, which have anti-inflammatory and antiseptic benefits.
For the shampoo to work, its active ingredients must penetrate the scalp and reach the hair follicles. Dr. Doshi explains, “That’s why many treatments recommend leaving the product on for a few minutes before rinsing—it allows better absorption.”
### What to Look for in a Hair Growth Shampoo
Experts suggest choosing shampoos that support scalp health, reduce hair fall, and strengthen strands. Gaunitz recommends formulas with natural ingredients that fight inflammation and microbial overgrowth. Key ingredients to look for include:
– Rosemary Oil: A 2015 study found it as effective as minoxidil in boosting hair growth. It improves circulation to follicles and reduces scalp inflammation.
– Tea Tree Oil: Its antimicrobial properties help maintain scalp health and reduce inflammation, making it ideal for buildup or flakiness.
– Green Tea Extract: Rich in antioxidants, it may block DHT, a hormone linked to hair loss, helping preserve follicles.
– Saw Palmetto: This botanical may inhibit the enzyme that converts testosterone to DHT, potentially slowing hair loss in both men and women.
– Biotin: Supports keratin production, strengthening hair and reducing breakage.
Gaunitz also advises checking the first five ingredients—they make up most of the formula. Avoid harsh surfactants and parabens, and opt for nourishing, natural actives for healthier, fuller hair.Biotin and Hair Health
“Biotin is a B vitamin that helps produce keratin, a key protein for healthy hair,” says Dr. Rambhia. While biotin deficiency is uncommon, supplements only benefit those who lack this vitamin.
Keratin: This protein strengthens hair and adds elasticity. “It doesn’t stimulate new growth but can temporarily thicken existing strands,” explains Dr. Rambhia. Many strengthening shampoos contain keratin to improve hair texture.
Collagen: It provides amino acids needed for hair protein production. However, Dr. Rambhia notes that “shampoos with collagen likely have minimal impact on growth,” since it doesn’t deeply penetrate the scalp.
Aloe: Known for soothing dry, irritated scalps, aloe has anti-inflammatory benefits. “A calm scalp supports better hair follicle function,” says Dr. Rambhia.
### What is Biotin?
“Biotin, or vitamin B7, is a water-soluble vitamin vital for metabolism, energy production, and cell function,” explains Dr. Doshi. “It also aids in keratin formation, which builds hair, skin, and nails.” While biotin is found in foods like eggs, nuts, and vegetables, absorption varies. Supplements may help, but their effectiveness for hair growth is still being studied.
### What Causes Hair Loss?
Hair loss can stem from genetics, medical conditions, stress, diet, or hormones. Gaunitz categorizes the main causes:
1. Genetics: Sensitivity to DHT leads to pattern hair loss (androgenetic alopecia).
2. Nutritional Deficiencies: Low levels of vitamin D3, zinc, iron, or B vitamins can trigger hair loss.
3. Inflammation: Conditions like alopecia areata or scalp irritation contribute to hair thinning.
### Other Hair Loss Treatments
“Beyond minoxidil and finasteride, options include laser therapy, platelet-rich plasma (PRP) injections, hair transplants, or medications like spironolactone for hormonal issues,” says Dr. Doshi. Results vary, so consulting a specialist for a tailored plan is best.
