What products should I take to support my hair growth?

The best hair-growth products depend on why your hair is thinning (genetics, shedding after stress/illness, nutrient deficiency, breakage, hormones, scalp issues). There isn’t one product that works for everyone, but these are the options with the strongest evidence or practical benefit.

1. Clinically proven regrowth: Minoxidil (most evidence)

If you have pattern thinning (widening part, thinning crown, receding hairline), start here.

• Rogaine 5% minoxidil foam or solution — commonly used once daily for many women and twice daily for many men (follow the product directions). It can help slow hair loss and stimulate regrowth, but results usually take several months and require continued use.
• Lower-cost generic minoxidil options can work because the active ingredient is the same.

Good choice if: you notice gradual thinning rather than sudden shedding.

2. Hair-growth supplements (help some people, not magic)

Supplements are most useful when they address a deficiency or contain ingredients with some clinical support. Many popular “hair vitamins” (especially high-dose biotin alone) do not help unless you’re deficient.

Options with some evidence:

• Nutrafol — a multi-ingredient supplement with studies suggesting possible improvements in hair density for some people, though results vary.
• Viviscal — another supplement with some clinical research supporting reduced shedding/improved appearance in certain groups.

Before taking supplements, consider checking:

• Ferritin/iron
• Vitamin D
• Thyroid levels
• Zinc (if risk factors exist)

3. Scalp serums (supportive, not replacements for minoxidil)

These may help with scalp condition, breakage, or the appearance of fullness:

• The Ordinary Multi-Peptide Serum for Hair Density — a popular peptide-based option.
• Neutrogena Hair Restore Scalp Serum — designed to support scalp health and hair appearance.
• Nutrafol Lightweight Scalp Serum — aimed at reducing shedding related to breakage.

4. Shampoo: choose for scalp health, not “regrowth”

Most shampoos cannot regrow hair because they don’t stay on the scalp long enough to act like medications. They can help with breakage, oil, irritation, and making hair look fuller.

Examples:

• Nioxin thinning-hair systems — focus on scalp cleansing and thicker-looking hair.
• Viviscal Thickening Shampoo — helps with the appearance of fullness and reducing breakage.

A simple starter routine

If you’re noticing thinning:

1. Morning or evening: 5% minoxidil (if appropriate for you)
2. Gentle shampoo 2–4×/week based on your scalp type
3. Adequate protein intake + address any deficiencies
4. Take progress photos monthly (hair changes slowly)

A few questions would help me narrow this down:

1. Are you male or female, and what age range?
2. Is your issue shedding all over, a widening part, receding hairline, or bald spots?
3. How long has it been happening?
4. Do you want supplements, topical products, or the most effective overall plan regardless of category?

When looking to support hair growth through products and supplements, it helps to focus on ingredients backed by clinical research and recommended by dermatologists. Keep in mind that supplements work best if you have a nutritional gap or deficiency.

Clinically Backed Hair Growth Supplements

• Nutrafol is a leading multi-targeted, physician-recommended brand that uses a blend of stress adaptogens (like ashwagandha), marine collagen, and saw palmetto to address root causes of thinning like stress and hormones.
• Viviscal is a drug-free, clinically studied supplement featuring AminoMar (a proprietary marine collagen complex) alongside biotin and zinc to support shedding and nourish existing follicles.
• Targeted Micronutrients like Vitamin D, Iron (ferritin), Zinc, and B-complex vitamins (including Biotin) are frequently recommended if blood work reveals a deficiency affecting your hair cycle.

Topical and Scalp Treatments

• Minoxidil (Rogaine) is an over-the-counter topical treatment with the strongest FDA-approved and dermatologist-backed clinical evidence for actively stimulating hair follicles and prolonging the growth phase.
• Peptide & Growth Factor Serums (such as specialized scalp serums from brands like The Ordinary or medical-grade lines) help support scalp health and improve the immediate environment around the hair root.

If you'd like to narrow down your options, tell me:

• Are you noticing excessive shedding, slow growth, or overall thinning?
• Have you had any recent blood work checking your iron or vitamin levels?
• Are you looking for topical treatments, ingestible supplements, or both?

If your goal is actual hair growth rather than just making the hair look healthier, I’d prioritize evidence-backed treatments over “hair vitamins.” The right products depend heavily on why your hair is thinning.

What I’d consider

• Women's Rogaine 5% Minoxidil Foam - $29.97 (Walmart.com)

1. Minoxidil 5% — the strongest OTC option

• This is the product I’d put at the top of the list for pattern hair thinning.
• It can reduce shedding and stimulate regrowth, but it generally takes months, not weeks, to see meaningful results.
• You have to continue using it to maintain the benefit.
• The exact formulation/dosing depends on whether you're male or female, so I'd follow the package directions or your dermatologist's instructions.

2. Ketoconazole shampoo — if you have dandruff/itchy or inflamed scalp

• Nizoral Anti-Dandruff Shampoo 1% Ketoconazole - $16.88 (Walmart)
• Nizoral Anti-Dandruff Shampoo 1% Ketoconazole - $16.49 (CVS)

This isn't a primary hair-growth treatment, but controlling dandruff and scalp inflammation can make your scalp healthier. I'd consider it particularly if you have flaking, itching, redness, or oily buildup.

3. Gentle shampoo + moisturizing conditioner A gentle shampoo and conditioner won't make follicles grow new hair, but they can reduce breakage, which is important when hair is thinning or fragile. The American Academy of Dermatology specifically recommends gentle cleansing and moisturizing conditioning for people experiencing hair loss.

What I would not automatically buy

Biotin/hair-growth gummies, high-dose vitamins, or collagen supplements. If you're deficient in something such as iron, zinc, protein, or certain vitamins, correcting that deficiency can help hair regrow. But taking extra nutrients when you aren't deficient isn't necessarily beneficial—and excessive amounts of some nutrients can actually contribute to hair loss.

Biotin deficiency is relatively uncommon, and high-dose biotin can interfere with some blood tests.

A simple approach

If you're experiencing gradual thinning, I'd start with:

1. Minoxidil 5% if appropriate for you.
2. Gentle shampoo + conditioner to minimize breakage.
3. Ketoconazole 1% shampoo if you have dandruff/itching.
4. Rather than blindly taking supplements, ask your clinician whether you should check things such as iron/ferritin, thyroid function, vitamin D, B12, zinc, or other nutrients based on your situation. Hair loss has many possible causes, so identifying the cause matters.

If you tell me your age, whether you're male or female, where you're thinning (hairline, crown, part, all over, patches), how long it's been happening, and whether you're shedding a lot, I can narrow this down to a specific routine and products I'd choose for you.

Supporting hair growth effectively depends on addressing the underlying cause of shedding or thinning—whether it is nutritional, hormonal, or structural . Dermatologists generally categorize evidence-backed hair growth support into targeted topicals, clinically studied nutraceuticals, and specific foundational vitamins.

Topically Proven Treatments

• Minoxidil (Rogaine / Regaine): Widely recognized as the gold standard topical treatment. It is FDA-approved and clinically proven to prolong the anagen (growth) phase of hair follicles and reactivate shrunken follicles. Available in 2% or 5% strengths (solutions or foams).

Evidence-Based Supplements & Nutraceuticals

• Nutrafol: A heavily dermatologist-recommended nutraceutical that targets multi-factorial root causes of thinning (like stress, aging, and minor hormonal shifts) using standardized botanical ingredients like ashwagandha, saw palmetto, and marine collagen.
• Viviscal: A clinically researched dietary supplement built around a proprietary marine complex (AminoMar ) combined with biotin, zinc, and vitamin C to nourish existing follicles and reduce shedding.

Key Targeted Vitamins & Minerals (If Deficient)

• Vitamin D: Essential for supporting the creation of new hair follicles; deficiency is frequently linked to increased hair shedding.
• Iron (Ferritin): Low iron stores are a major, hidden culprit behind chronic diffuse hair thinning, particularly in premenopausal women.
• Biotin & B-Complex: Helpful if an actual deficiency exists, though dermatologists note it mostly improves overall structural integrity and brittle nails rather than accelerating growth unless you are depleted.
• Zinc: Supports tissue growth and repair of the hair follicle structure, keeping surrounding oil glands functioning smoothly.

To help me narrow down what will actually work best for you, could you tell me:

• Are you experiencing sudden shedding, gradual thinning , or looking for general length retention?
• Do you have any known deficiencies or underlying health conditions?

If your goal is actual hair growth rather than just making hair look thicker, I’d prioritize treatments with evidence over “hair vitamins.”

• Rogaine 5% Minoxidil Foam - $59.99 (CVS)
• CVS Health 5% Minoxidil Solution - $28.99 (CVS)
• Nizoral 1% Ketoconazole Shampoo - $20.99 (CVS)
• Bondi Boost HG Shampoo for Thinning Hair - $16.00 (Ulta Beauty)

What I’d consider

• 5% minoxidil: This is the strongest over-the-counter option for common pattern hair loss. It can stimulate regrowth and slow further loss. Results generally take several months and need continued use to maintain them.
• Ketoconazole 1% shampoo: Worth considering if you also have dandruff, itching, inflammation, or an oily/flaky scalp. It primarily treats the scalp condition rather than directly regrowing hair.
• Gentle shampoo + conditioner: This won't create new follicles, but minimizing breakage can make your hair appear fuller. The AAD recommends gentle shampooing and conditioning for thinning/falling hair.
• Hair-growth supplements: I would not automatically buy biotin, collagen, or a “hair/skin/nails” vitamin. Evidence is inconsistent, and supplements are most useful when you actually have a nutritional deficiency. Excess amounts of some nutrients can even worsen hair loss.
• Biotin specifically: High-dose biotin isn't something I'd take routinely unless you're deficient. It can interfere with certain blood tests and produce inaccurate results.

The important part

The best product depends on why your hair is thinning. Iron/protein/zinc deficiency, thyroid problems, stress-related shedding, hereditary hair loss, traction, and scalp disorders can all look different and require different treatment.

If you tell me your age, sex, whether you're noticing shedding vs. thinning/bald spots, where it's happening (hairline/crown/all over), and whether your scalp is itchy or flaky, I can narrow this down to a specific routine and products I'd choose for you.

The only FDA-approved over-the-counter active ingredient clinically proven to regrow hair is minoxidil (found in brands like Rogaine or Hers/Hims) , while targeted supplements and scalp treatments help support overall follicle health.

Selecting the right product depends on whether you prefer a medical topical treatment, a multi-nutrient supplement, or a scalp-strengthening formula.

Proven Regrowth Treatments

• Minoxidil 5% Topical Foam or Solution — A daily topical medication that prolongs the hair growth cycle and reactivates shrinking follicles.
• Finasteride — A prescription oral or topical DHT-blocker typically used by men (and prescribed selectively for post-menopausal women) to stop hormonal hair thinning.

Hair Growth Supplements

• Nutrafol Hair Growth Nutraceutical — A multi-ingredient physician-formulated supplement targeting stress, lifestyle, and nutritional factors affecting shedding.
• Viviscal Hair Growth Supplement — A marine protein-based supplement clinically studied to nourish thinning hair and promote existing growth.
• Targeted Micronutrients — Dermatologists recommend checking for specific deficiencies in Vitamin D, Iron , or Zinc before supplementing, as excess amounts (especially high-dose biotin) can alter important lab test results without increasing growth.

Topical Serums and Oils

• The Ordinary Peptide Hair Density Serum — A concentrated, lightweight leave-in scalp treatment utilizing peptide complexes to support a denser-looking head of hair.
• Rosemary Essential Oil — Diluted natural oils massaged into the scalp can improve local blood circulation and cellular health around the root.

If you can share your primary symptoms (such as overall thinning, receding edges, or postpartum shedding) and your current routine , I can help you choose the most appropriate product type.

If your goal is actual hair regrowth, I’d prioritize proven treatments over “hair vitamins.” The right products depend on whether you’re dealing with gradual thinning, shedding, breakage, dandruff, or a receding hairline.

My top picks

Women's Rogaine 5% Minoxidil Foam

$29.97

1. 5% minoxidil foam — best-supported OTC option
Minoxidil can stimulate growth and slow further hair loss. Dermatologists generally recommend it for pattern hair loss, but it takes months to judge the result and you need to continue using it to maintain the benefit.

There are versions marketed for both men and women; the appropriate strength/use can differ. Avoid minoxidil during pregnancy or breastfeeding.

Women's Rogaine 5% Minoxidil Foam

$29.97

Men's Rogaine 5% Minoxidil Foam

$58.67

Equate 5% Minoxidil Foam

$32.94

2. Ketoconazole shampoo — if you have dandruff/itchy or inflamed scalp
A 1% ketoconazole shampoo such as Nizoral can help control dandruff and scalp inflammation. It isn't a primary hair-regrowth treatment, but keeping the scalp healthy can be useful if dandruff is contributing to irritation.

Nizoral Anti-Dandruff Shampoo 1% Ketoconazole

$16.88

3. Don't automatically buy biotin or “hair growth gummies.”
Biotin deficiency is uncommon, and there is little evidence that high-dose biotin makes hair grow faster in people who aren't deficient. High-dose biotin can also interfere with certain blood tests.

Likewise, iron or zinc should generally be supplemented only when testing shows you're deficient; taking too much can be harmful.

If I were putting together a simple routine

• Morning/evening: minoxidil as directed on the scalp.
• Regular shampoo: gentle shampoo/conditioner that minimizes breakage.
• If you have dandruff: add ketoconazole shampoo according to its label.
• Nutrition: prioritize adequate protein and a balanced diet rather than megadose hair supplements.

If you're experiencing sudden or substantial shedding, bald patches, scalp pain/itching, or rapid thinning, I'd see a dermatologist rather than trying a bunch of products—hair loss has many possible causes and treatment is much more effective when the cause is identified.

If you tell me your age, sex, where you're losing/thinning hair (hairline, crown, all over, etc.), and whether it's shedding or gradual thinning, I can narrow this down to the 2–3 products I'd actually recommend for you.

Supporting hair growth effectively depends heavily on the underlying cause of your thinning or slow growth (e.g., stress, hormonal shifts, nutritional gaps, or genetics). Over-the-counter options range from targeted dietary supplements to topical treatments.

Clinically Backed Topical Treatments

• Minoxidil (Rogaine / Hers / Hims) — The gold standard over-the-counter active ingredient. It is FDA-approved, widely recommended by dermatologists, and works by increasing blood flow and revitalizing dormant hair follicles. Available in 2% or 5% topical solutions and foams.
• Scalp Serums and Peptides (The Ordinary Multi-Peptide Serum , Vegamour GRO) — Leave-in topical treatments featuring caffeine, red clover extract, or multi-peptides designed to improve scalp circulation and anchor hair strands at the root.

Targeted Hair Growth Supplements

• Nutrafol (Women / Men / Balance) — A physician-formulated nutraceutical that targets multiple root causes of thinning hair like stress, lifestyle, and minor nutritional shifts using ingredients like ashwagandha, marine collagen, and tocotrienols.
• Viviscal — A long-standing, heavily researched marine-protein supplement (featuring their AminoMar complex) blended with biotin and zinc to support thinning hair due to stress or age.
• Key Foundational Nutrients (Iron, Zinc, Vitamin D) — Single or combination supplements are most effective if you have an active deficiency. (Note: Dermatologists often advise against mega-dose biotin unless you are deficient, as high amounts can interfere with routine lab bloodwork).

Real Experiences with Hair Growth Regimens

Community members frequently share that finding the right match takes patience and consistency:

To help me narrow down what might work best for you, could you share:

• Your primary symptoms (e.g., overall thinning, postpartum shedding, a receding hairline, or slow growth)
• Whether you prefer an internal supplement or a topical treatment

If your goal is actual hair growth rather than just making the hair look thicker, I’d keep the routine fairly simple. The best products depend a lot on whether you're dealing with shedding, thinning, breakage, or a receding hairline.

My top picks

Rogaine Women's 5% Minoxidil Foam

$37.49

Rogaine Men's 5% Minoxidil Foam

$59.99

Bondi Boost HG Shampoo for Thinning Hair

$16.00

Mielle Rosemary Mint Strengthening Shampoo

$16.99

1. 5% minoxidil foam — the most evidence-based OTC option
For hereditary/pattern hair loss, topical minoxidil can stimulate growth and reduce further loss. Results generally take 6–12 months, and you need to keep using it to maintain the benefit.

2. Gentle shampoo — mainly for scalp/hair health
A shampoo can help with cleansing and reducing breakage, but don't expect a shampoo alone to regrow significantly lost hair. The Bondi Boost or Mielle options above are reasonable cosmetic choices.

3. Don't automatically buy biotin or "hair vitamins."
Biotin deficiency is rare, and NIH says there's little evidence that high-dose biotin improves hair growth in people who aren't deficient. High doses can also interfere with certain blood tests.

4. Iron, zinc, vitamin D, etc. — only if you're deficient.
Low iron, protein, zinc, or other nutrients can contribute to hair loss, but taking extra when your levels are normal isn't necessarily helpful and can sometimes be harmful. A dermatologist can determine whether blood testing is appropriate.

If I were putting together a basic routine

• Morning: gentle shampoo/conditioner as needed + normal hair care
• Daily: 5% minoxidil if appropriate for your type of hair loss
• Diet: adequate protein and overall calories
• Avoid: high-dose "hair growth" supplements unless a deficiency has been identified

If you tell me your age, whether you're male or female, where you're thinning (hairline/crown/part/all over), and whether you're shedding or breaking, I can narrow this down to the 3–5 products I'd actually buy for your situation.
