For supplements, Nutrafol and Viviscal are the leading choices to reduce shedding and improve density; choose
Nutrafol or Viviscal based on ingredient preference. For proven topical regrowth use Minoxidil, noting it must be used continuously to maintain results. Shampoos and serums (e.g.,
Vegamour, , Briogeo) can help density but are adjuncts to supplements or topical treatment.

Nutrafol is best if you want a clinically tested oral supplement that targets root causes like stress or hormones to strengthen follicles and improve density; expect gradual results over months.

Viviscal is a top choice for those preferring marine collagen and botanical supplements to reduce shedding and boost thickness; it’s recommended alongside Nutrafol, so pick by ingredients and tolerance.

The best hair-growth products depend on why your hair is thinning (genetics, stress/shedding, nutrient deficiency, scalp issues, breakage, hormones, etc.). A good starting routine is usually a mix of a proven growth treatment plus scalp/hair support.
Topical minoxidil (most evidence-backed over-the-counter option)
Look for 5% minoxidil foam or solution (commonly sold as Rogaine or store brands).
It can help slow shedding and stimulate regrowth in many people when used consistently. Results often take 3–6+ months.
Examples: Rogaine 5% Minoxidil Foam
Hair-growth supplements (optional, not magic)
Some supplements have shown modest benefits in studies, especially multi-ingredient formulas, but results vary and they work best when there is a nutritional or shedding-related component.
Options with some clinical research include:
Nutrafol
Viviscal
Avoid taking high-dose biotin just because it is marketed for hair growth; it usually does not help unless you are deficient and can interfere with some lab tests.
Gentle scalp-support shampoos
These can improve scalp condition and reduce breakage, but most shampoos alone do not regrow hair.
Examples:
Viviscal Thickening Shampoo
DS Laboratories Revita Hair Density Shampoo
Morning
Night
Weekly

Supporting hair growth effectively depends heavily on the underlying cause of your thinning or shedding—whether it's genetic, stress-related, hormonal, or nutritional.[](https://www.dinastrachanmd.com/blog/a/general-dermatology/hair-and-scalp/5-dermatologist-recommended-hair-growth-products/)…

If your goal is actual hair growth rather than just making hair look thicker, I’d focus on a few evidence-based products and avoid spending much on “hair vitamins.”
Minoxidil 5% — This is the strongest over-the-counter option for common pattern hair loss. It can stimulate growth and slow further loss, but you generally need consistent use for months and must continue using it to maintain the benefit.
Men's Rogaine 5% Minoxidil Foam Hair Loss Treatment - $29.97 (Walmart.com)
If you're a woman, there are formulations specifically marketed for women:
Women's Rogaine 5% Minoxidil Foam - $58.65 (Target)
Gentle shampoo + conditioner — Shampoo won't generally regrow hair, but a gentle routine can reduce breakage and help thinning hair look healthier. The AAD recommends gentle shampoo and moisturizing conditioner for people experiencing hair loss.
Ketoconazole shampoo if you have dandruff/itching/flaking — For example, 1% ketoconazole shampoo can help control dandruff and scalp inflammation. I wouldn't use it specifically as your primary hair-growth treatment, though.
Nizoral Anti-Dandruff Shampoo 1% Ketoconazole - $16.88 (Walmart)
I'd skip high-dose biotin unless you actually have a deficiency. Biotin deficiency is uncommon, and high doses can interfere with blood-test results. Similarly, iron and zinc should generally be supplemented when testing shows you're deficient; too much can actually be harmful.
If you're experiencing significant shedding, it can be much more useful to determine why you're losing hair—nutritional deficiency, thyroid problems, hormonal changes, pattern hair loss, stress/illness, scalp conditions, etc.—than to buy a collection of supplements.
If you tell me your age, sex, whether the issue is thinning vs. shedding, and where you're losing hair (hairline, crown, part, or all over), I can give you a specific product routine and tell you which products are actually worth buying.

The absolute best product for you depends on whether you are experiencing severe hair thinning or simply want to maximize your overall hair health. To give you the most accurate answer, topical minoxidil is the only over-the-counter medical ingredient clinically proven by the FDA to grow new hair . While popular dietary supplements like biotin do not grow new hair in healthy individuals, certain targeted multi-ingredient formulas can successfully improve existing density and reduce shedding.
The top hair growth options are detailed below, categorized by what they excel at:
🔬 Proven Clinical Hair Regrowth
These products directly reactivate dormant hair follicles and prolong the hair's active growing phase.
🌿 Nutrient & Density Optimization
These multi-ingredient nutraceuticals address internal factors like stress and nutritional gaps to minimize shedding and maximize thickness.
🧼 Scalp Health & Support
A healthy scalp environment is necessary to prevent hair breakage and support new follicle growth.
To help narrow down the best solution, could you share if your hair thinning is concentrated in specific areas (like the hairline or crown) or if it is a general, all-over shedding ? Sharing your biological sex would also help pinpoint the safest and most effective formula options.

Hair growth products depend a lot on why your hair is thinning (genetics, stress shedding, hormones, nutrient deficiencies, scalp issues, breakage, etc.). The products with the strongest evidence are not always the ones marketed as “hair vitamins.”
Here are the options I’d consider:
Examples:
Good for: widening part, thinning crown, gradual genetic thinning. Expect: possible shedding at first; results usually require several months of consistent use.
Supplements can help if they address a deficiency or may modestly help some people, but they are not a guaranteed fix. Biotin, for example, usually does not improve hair growth unless you are deficient.
Commonly used options:
Before taking supplements, it can be useful to check whether you have low:
These may help improve the scalp environment or reduce breakage, but they generally have less evidence than minoxidil.
Examples:

These won’t usually regrow lost hair, but they can reduce breakage and improve fullness:

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.
If you have pattern thinning (widening part, thinning crown, receding hairline), start here.
Good choice if: you notice gradual thinning rather than sudden shedding.
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:
Before taking supplements, consider checking:
These may help with scalp condition, breakage, or the appearance of fullness:
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.
