Hair health reflects internal well-being as much as external care. In 2025, the conversation around hair loss and thinning has shifted from stigma to strategy. With modern nutraceutical science at the forefront, individuals are increasingly turning to the best hair growth supplements to address deficiencies, hormonal imbalances, and environmental stressors that compromise scalp vitality.

While topical serums and salon treatments offer temporary improvements, true restoration begins within. Targeted supplementation has shown measurable results in improving hair density, stimulating follicles, and reducing breakage. The formulations gaining momentum this year combine time-tested botanicals, amino acids, and advanced delivery systems to optimize absorption and effectiveness.

Here are the top-performing best hair growth supplements in 2025—each backed by science, trusted by professionals, and endorsed by those who’ve witnessed transformation firsthand.

1. Nutrafol Women & Nutrafol Men

Nutrafol remains a pioneering name in the field of nutraceuticals. Its gender-specific formulas are meticulously designed to counteract stress, hormonal imbalances, and poor nutrition—three major causes of hair thinning.

The formulation includes saw palmetto to inhibit DHT (a hormone linked to follicle shrinkage), marine collagen to enhance structural integrity, and ashwagandha to reduce cortisol. The result is visibly thicker, fuller hair within three to six months. Its continued dominance in rankings of the best hair growth supplements is attributed to both clinical trials and consistently positive user feedback.

2. Viviscal Pro

Trusted by trichologists and dermatologists globally, Viviscal Pro features a proprietary AminoMar™ marine complex, originally developed based on a Scandinavian diet rich in fish proteins.

In combination with biotin, apple extract, and vitamin C, Viviscal Pro strengthens existing strands and stimulates new growth, especially in individuals experiencing shedding due to stress or postpartum hormonal shifts. Among professionals, it is regarded as one of the best hair growth supplements for its clinical pedigree and long-standing efficacy.

3. NutriRise Hair Growth Complex

Emerging as a standout in 2025, NutriRise Hair Growth Complex addresses hair loss through an adaptogenic approach. The formula contains reishi mushroom, fo-ti root, and organic bamboo silica, aiming to improve circulation, reduce inflammation, and nourish the scalp from within.

The inclusion of methylated B vitamins ensures optimal bioavailability for individuals with genetic methylation issues. With visible improvements in hair luster and volume, it is rapidly earning its place among the best hair growth supplements available today.

4. Ouai Thick & Full Supplements

Known for its stylish haircare products, Ouai’s internal supplement line continues to impress. The Thick & Full formula combines pea sprout extract, biotin, and amino acids to boost keratin production and fortify hair from root to tip.

Unlike conventional tablets, Ouai utilizes microencapsulation for slow release, ensuring sustained nutrient delivery throughout the day. For those seeking both aesthetic elegance and clinical-grade results, Ouai’s entry among the best hair growth supplements in 2025 is well deserved.

5. Moon Juice SuperHair

Moon Juice’s SuperHair capsule is a holistic powerhouse. Infused with adaptogens like rhodiola and ashwagandha, alongside plant-based iron and biotin, this supplement targets the stress-hair loss connection with precision.

It also includes saw palmetto and tocotrienols (a potent form of vitamin E) to reduce oxidative damage and hormonal imbalances. As part of a broader wellness protocol, SuperHair stands out among the best hair growth supplements for its emphasis on adrenal support and systemic harmony.

6. Hims & Hers Biotin Gummies

For those preferring chewable formats, Hims & Hers biotin gummies offer a palatable and effective solution. Containing 5000 mcg of biotin per serving, these supplements enhance keratin infrastructure, promoting thicker hair and stronger nails.

Although simple in formulation, the high concentration of biotin and customer-reported improvements position them among the best hair growth supplements for individuals beginning their journey or addressing mild thinning.

7. Thorne BioComplex Hair Support

Thorne, a leader in clinical-grade supplementation, offers BioComplex Hair Support with a formulation rooted in mitochondrial health and cellular regeneration. Its blend includes nicotinamide riboside (a precursor to NAD+), taurine, zinc bisglycinate, and polyphenol-rich botanicals.

The emphasis on cellular energy production makes this supplement particularly beneficial for age-related thinning. As concerns about biological aging increase, BioComplex is establishing itself as one of the most sophisticated best hair growth supplements on the market.

Why These Supplements Work

The effectiveness of the best hair growth supplements hinges on their ability to support hair at every stage of the growth cycle. This includes:

• Anagen (Growth Phase): Nutrients like biotin, zinc, and amino acids provide the building blocks for keratin synthesis.
• Catagen (Transitional Phase): Adaptogens help reduce the impact of cortisol, which can prematurely shift follicles into rest mode.
• Telogen (Resting Phase): Antioxidants and circulatory enhancers minimize inflammation and prepare the scalp for renewed activity.

Moreover, many of these supplements are designed to be bioavailable—meaning they are readily absorbed and utilized by the body. This is crucial for individuals with compromised gut health or absorption issues.

Considerations Before Choosing a Supplement

While the market is saturated, not all products deliver measurable results. To select from the best hair growth supplements, consider the following:

• Ingredient Transparency: Avoid proprietary blends that obscure dosages.
• Clinical Backing: Look for peer-reviewed studies or dermatologist endorsements.
• Lifestyle Compatibility: Some supplements are vegan, allergen-free, or specifically tailored for hormonal causes.
• Duration of Use: Most require at least 3–6 months of consistent use for visible effects.

Hair growth is a gradual process, and patience—combined with the right formulation—is key to success.

In 2025, the pursuit of healthy, voluminous hair has evolved from a cosmetic concern into a comprehensive wellness goal. As the list of clinically tested and user-trusted best hair growth supplements expands, individuals now have access to personalized solutions that go beyond surface-level fixes.

By investing in internal nourishment, the path to resilient, radiant hair becomes not only attainable but sustainable. Whether addressing stress-related shedding or age-induced thinning, these supplements offer a modern, science-backed approach to restoring confidence—strand by strand.
