In this comprehensive guide, we've have compiled the 10 best hair growth serums of 2025 that work for everyone, regardless of hair type, texture, or gender.

10. Briogeo Destined for Density Peptide Density Serum
Briogeo's clean formula combines vegan peptides with energizing biotin and caffeine to wake up dormant follicles and promote visibly thicker hair across all hair types and textures.
Briogeo has built its reputation on creating inclusive hair care products that truly work for everyone, regardless of hair type, texture, or ethnicity. The Destined for Density serum lives up to that promise with a thoughtfully formulated blend that addresses the diverse needs of straight, wavy, curly, and coily hair alike.
The star ingredient is copper peptides, which have been extensively studied for their ability to stimulate hair follicles and prolong the growth phase of the hair cycle. Copper peptides also act as antioxidants, protecting hair follicles from environmental damage and oxidative stress that can accelerate hair loss. Combined with biotin for strengthening and caffeine for stimulation, the formula creates a powerful trifecta that tackles hair thinning from multiple angles.
Zinc is included to regulate oil production and reduce inflammation, making this particularly effective for those dealing with scalp issues like dandruff or seborrheic dermatitis that can interfere with healthy hair growth. The serum has a gel-like texture that spreads easily across the scalp without running or dripping, and it absorbs quickly without leaving any sticky residue or affecting your hair's natural texture.
Users with textured hair especially appreciate that Briogeo understands their unique needs. The formula doesn't dry out the scalp or strip natural oils, which is crucial for maintaining healthy coily or curly hair. It also doesn't interfere with common styling products used in textured hair routines. After 3-4 months of consistent use, most users report seeing more baby hairs along their hairline, increased overall density, and noticeably less shedding when detangling or styling. The brand is also committed to clean beauty standards, with formulas free from sulfates, silicones, parabens, phthalates, and artificial dyes.
- Key Ingredients: Copper peptides, biotin, caffeine, zinc
- Pros: Clean and vegan, works on all hair types, strengthens existing hair, pleasant texture
- Cons: Mid-range price, requires consistent use
- Price Range: $54-58 (Approx)
9. Pura D'Or Hair Thinning Therapy Serum
Pura D'Or offers a gentler, more natural approach to hair growth with a blend of 15+ DHT blockers including saw palmetto, pumpkin seed oil, and black cumin seed oil.
For those who prefer a completely natural, plant-based approach to hair growth, Pura D'Or delivers without compromise. This serum is formulated without any synthetic ingredients, sulfates, parabens, or harsh chemicals, making it an excellent choice for anyone with chemical sensitivities or those following a clean beauty lifestyle.
The formula's strength lies in its comprehensive blend of natural DHT blockers. DHT (dihydrotestosterone) is a hormone that shrinks hair follicles and is the primary culprit behind androgenetic alopecia, or pattern baldness. Pura D'Or attacks this problem from multiple angles with saw palmetto, which has been shown in studies to block DHT as effectively as some prescription medications, along with pumpkin seed oil, nettle extract, and black cumin seed oil.
The serum also includes biotin for strengthening, niacin for circulation, and argan oil for moisturizing and protecting the scalp. While the results may take longer to appear compared to products with minoxidil or advanced peptide complexes, users appreciate the gentle, non-irritating formula that they can feel good about using long-term.
One thing to note is that the serum has a distinctive herbal, earthy scent from all the botanical oils. Some users love the natural fragrance while others find it too strong, especially immediately after application. The texture is also slightly oily, which works well for those with dry scalps but might feel heavy for those with naturally oily hair. Despite these minor considerations, Pura D'Or has built a loyal following of users who have seen genuine improvements in hair density and reduced shedding after 4-6 months of consistent use. It's also one of the most affordable options in the natural hair growth category.
- Key Ingredients: Biotin, niacin, argan oil, saw palmetto, pumpkin seed oil
- Pros: Natural and organic ingredients, no harsh chemicals, good value, suitable for sensitive scalps
- Cons: Results take longer, herbal scent, oily texture
- Price Range: $30-40 (Approx)
8. Virtue Flourish Density Booster
Virtue's patented Alpha Keratin 60ku technology helps repair and strengthen fine, thinning hair while creating the appearance of increased density immediately upon application.
Virtue has cracked the code on fine hair with their groundbreaking Alpha Keratin 60ku protein, which is identical to the keratin naturally found in human hair. This isn't your typical hydrolyzed keratin that sits on the surface. Alpha Keratin 60ku actually penetrates the hair shaft and binds to damaged areas, essentially filling in gaps and reinforcing weak spots from the inside out.
The Density Booster works on two fronts: immediate cosmetic improvement and long-term hair health. Upon application, fine hair appears visibly thicker and fuller because the keratin adds actual substance to each strand. Over weeks and months of consistent use, hair becomes genuinely stronger, less prone to breakage, and better able to hold styles. The formula also includes biotin for keratin production, niacinamide for scalp circulation, and amino acids that serve as building blocks for healthy hair growth.
What sets this apart for fine-haired individuals is that it provides volume and body without any heaviness or residue. Many volumizing products can leave fine hair feeling sticky, crunchy, or weighed down, but Virtue's serum remains lightweight while delivering noticeable thickness. Users with baby-fine hair report being able to see their scalp less and feeling like their ponytails have more substance.
Clinical studies showed a 62% reduction in breakage and visible improvements in hair thickness after eight weeks of use. The serum has a pleasant, subtle scent and a silky texture that distributes easily through the hair. It can be applied to both the scalp and lengths, making it more versatile than scalp-only treatments.
- Key Ingredients: Alpha Keratin 60ku, biotin, niacinamide, amino acids
- Pros: Immediate volumizing effect, strengthens hair, lightweight formula, suitable for daily use
- Cons: Expensive, keratin source may concern some consumers
- Price Range: $98-108 (Approx)
7. Act+Acre Cold Processed Scalp Renew
Act+Acre takes a farm-to-follicle approach with cold-pressed, sustainable ingredients. Their Scalp Renew serum balances the scalp's pH while delivering nutrients that support healthy hair growth.
Act+Acre is pioneering a new standard in hair care by treating scalp health with the same seriousness as skincare. Their philosophy is simple: healthy hair grows from a healthy scalp. The Scalp Renew serum uses cold-processed ingredients to preserve the maximum nutritional value of each botanical component, similar to how cold-pressed juices retain more vitamins than heat-processed alternatives.
The formula features the Baicapil peptide complex, which has shown in studies to reduce hair loss by 58% and increase hair density by 42% after just three months. It's combined with pumpkin seed extract, a natural DHT blocker, and castor oil, which has been used for centuries to promote hair growth and thickness. What makes this serum unique is its focus on creating an optimal pH environment on the scalp, which is crucial for healthy microbial balance.
Users with sensitive, irritated, or flaky scalps see particularly impressive results. The serum calms inflammation, reduces itching, and helps normalize oil production without stripping the scalp. Many report that their scalp simply feels healthier and more comfortable within the first few weeks, with hair growth improvements becoming visible around month three.
Act+Acre is committed to sustainability with recyclable packaging and carbon-neutral shipping. The brand is certified by multiple clean beauty organizations and is completely free from silicones, sulfates, parabens, and synthetic fragrances. If you're someone who values both effectiveness and environmental responsibility, this serum aligns with those principles while delivering real results.
- Key Ingredients: Baicapil peptide complex, pumpkin seed extract, castor oil
- Pros: Clean beauty certified, sustainable sourcing, improves scalp texture, reduces flaking
- Cons: Takes time to see results, higher price point
- Price Range: $68-72 (Approx)
6. Aveda Invati Advanced Scalp Revitalizer
Aveda's Invati line is specifically designed to invigorate the scalp and thicken hair from the root. The Scalp Revitalizer uses a blend of Ayurvedic herbs and cutting-edge technology to reduce hair loss.
Invati means "invigorate" in Sanskrit, and that's exactly what this serum does. Aveda combines ancient Ayurvedic wisdom with modern hair science to create a formula that addresses thinning hair at multiple levels. The serum contains turmeric and ginseng, both revered in traditional medicine for their circulation-boosting and anti-inflammatory properties, along with salicylic acid to exfoliate the scalp and clear follicle openings.
The brand's proprietary Invati Advanced complex works to thicken hair from the roots while reducing breakage. Clinical testing by Aveda showed a 53% reduction in hair loss due to breakage after 12 weeks of use. Users consistently report that their hair feels thicker, stronger, and more resilient with continued use.
One standout feature is the energizing scalp massage you get with each application. The serum comes with a unique applicator that allows you to massage the product directly into the scalp, which not only feels amazing but also stimulates blood flow to wake up sluggish follicles. Many users describe this as a spa-like ritual that makes them actually look forward to their daily treatment.
The serum has a distinctive herbal scent profile featuring notes of bergamot and vanilla alongside the natural plant extracts. While most users find it pleasant and refreshing, those sensitive to fragrances might find it strong at first. The scent does dissipate within 10-15 minutes of application. This is an excellent choice for anyone noticing progressive thinning who wants a luxurious, sensorial experience alongside effective results.
- Key Ingredients: Turmeric, ginseng, tangerine peel, salicylic acid
- Pros: Natural ingredients, pleasant scent, reduces breakage, improves scalp condition
- Cons: Strong herbal scent may not suit everyone, mid-to-high price point
- Price Range: $85-95 (Approx)
5. Nutrafol Growth Activator Hair Serum
Nutrafol's Growth Activator goes beyond just hair growth by addressing the scalp microbiome. This serum combines ashwagandha, microalgae extract, and other botanicals to create optimal conditions for healthy hair growth.
Nutrafol takes a holistic, wellness-focused approach to hair growth that considers the scalp as an ecosystem. The brand is known for its popular hair growth supplements, and this topical serum was developed to complement that internal approach with external care. The formula targets multiple root causes of hair thinning including stress, inflammation, hormonal imbalances, and environmental damage.
Ashwagandha, an adaptogenic herb, helps manage the cortisol response that contributes to stress-related hair loss. The microalgae extract provides essential amino acids and minerals that nourish follicles, while specialized peptides signal dormant follicles to reactivate. The serum also includes vegan collagen and biomimetic peptides that strengthen the hair shaft and improve density.
What users love most is how this serum improves overall scalp health. Within weeks, many notice reduced scalp irritation, less flaking, and a more balanced oil production. The scalp feels healthier, which creates the perfect environment for robust hair growth. Clinical studies conducted by Nutrafol showed that users experienced 30% more visible hair thickness and a 25% increase in hair count after 3-6 months of consistent use.
The serum has a cooling, soothing sensation upon application that feels therapeutic, especially for those with inflamed or irritated scalps. While it works well on its own, Nutrafol recommends using it alongside their supplements for maximum results, which does make it a more expensive overall investment.
- Key Ingredients: Ashwagandha, microalgae extract, peptides
- Pros: Holistic approach, reduces inflammation, improves scalp health, clean ingredients
- Cons: Expensive, works best when paired with Nutrafol supplements
- Price Range: $88-98 (Approx)
4. Olaplex No. 7 Bonding Oil + Intensive Bond Building Hair Treatment
While primarily known for bond repair, Olaplex No. 7 creates the ideal foundation for hair growth by strengthening strands from within and improving overall hair health and elasticity.
Olaplex revolutionized hair care with its patented bond-building technology, and while it's not marketed specifically as a growth serum, it addresses a crucial aspect of hair health that many growth products overlook. You can't grow long, healthy hair if it's constantly breaking off. Olaplex No. 7 repairs disulfide bonds that are broken during chemical treatments, heat styling, and environmental damage, resulting in dramatically stronger hair that can actually reach its full length potential.
The lightweight oil provides immediate results you can see and feel. Hair becomes noticeably shinier, smoother, and more manageable after just one use. Over time, consistent use reduces breakage by up to 68%, which means the hair you're growing can actually survive long enough to add visible length and density to your overall appearance.
This product is particularly beneficial for anyone who colors their hair, uses heat tools regularly, or has naturally fragile hair that tends to snap easily. The formula works on all hair types and textures, from pin-straight to tightly coiled. It also provides heat protection up to 450°F, making it a multitasking product that simplifies your routine.
Apply a small amount to damp hair, focusing on mid-lengths to ends, before styling. While it can be used on the scalp, it's designed more for the hair shaft than follicular stimulation. Pair it with a dedicated growth serum applied directly to the scalp for a comprehensive approach to achieving longer, thicker hair.
- Key Ingredients: Bis-Aminopropyl Diglycol Dimaleate, various plant oils
- Pros: Repairs and protects, heat protectant, adds shine, improves hair texture
- Cons: Not specifically formulated for growth, pricey for the size
- Price Range: $30-32 (Approx)
3. Rogaine 5% Minoxidil Foam
When it comes to clinically-proven hair regrowth, Rogaine remains the gold standard. The FDA-approved 5% minoxidil formula has decades of research backing its effectiveness for both men and women.
Rogaine is the heavyweight champion of hair regrowth with over 40 years of clinical research and millions of success stories. Minoxidil, its active ingredient, is the only topical treatment approved by the FDA specifically for hair regrowth. It works by widening blood vessels in the scalp, which improves blood flow to hair follicles, delivers more oxygen and nutrients, and extends the growth phase of the hair cycle.
The foam formulation is a significant improvement over the original liquid version, offering easier application and faster drying time with less scalp irritation. Most users report seeing less shedding within 6-8 weeks, with new hair growth becoming visible around month 4. Clinical studies show that 81% of women using 5% minoxidil foam experienced hair regrowth after 6 months of twice-daily use.
It's important to note that minoxidil requires commitment. You'll need to apply it twice daily indefinitely because stopping use will result in losing the gains you've made within a few months. Some users experience an initial "shedding phase" in weeks 2-8, which is actually a positive sign that the treatment is working to replace weak hairs with stronger ones. The foam can cause dryness or flaking for some users, but this can usually be managed with a gentle moisturizing scalp treatment. If you want results backed by serious science and are willing to commit to the routine, Rogaine delivers on its promises more consistently than almost any other option on the market.
- Key Ingredients: 5% Minoxidil
- Pros: FDA-approved, extensively researched, visible results in 3-6 months, widely available
- Cons: Requires indefinite use, may cause initial shedding, can dry out scalp
- Price Range: $35-50 (Approx)
2. The Ordinary Multi-Peptide Serum for Hair Density
The Ordinary proves that effective hair care doesn't have to break the bank. This peptide-rich serum supports hair health and creates an optimal scalp environment for growth at an unbeatable price.
Don't let the low price fool you. This serum is packed with some of the most researched and effective hair growth ingredients available. The REDENSYL complex, which costs significantly more than minoxidil to produce, works by targeting stem cells and encouraging them to produce new hair. Clinical studies on REDENSYL show a 214% increase in hair growth after just three months of use.
The formula also includes Procapil, a blend that improves blood flow to hair follicles and prevents follicle aging, plus caffeine to stimulate the scalp and biotin to strengthen each strand. The serum has a thin, water-like consistency that spreads easily across the scalp without feeling heavy or greasy. While it doesn't have the luxurious feel of more expensive options, it absorbs completely within minutes.
Users appreciate that The Ordinary keeps things simple with no added fragrances, unnecessary fillers, or fancy packaging that drives up costs. The result is a no-nonsense product that delivers real results for a fraction of what you'd spend on luxury brands. It's perfect for anyone new to hair growth serums who wants to test the waters without a major investment, or for those on a budget who still want scientifically-backed ingredients.
- Key Ingredients: REDENSYL complex, Procapil, biotin, caffeine
- Pros: Affordable, science-backed ingredients, lightweight formula, works for all hair types
- Cons: May take longer to see results, subtle scent some find medicinal
- Price Range: $17-20 (Approx)
1. Vegamour GRO Hair Serum
Vegamour's GRO Hair Serum continues to dominate in 2025 with its powerful plant-based formula. This vegan serum uses a proprietary blend of mung bean, red clover, and curcumin to promote thicker, fuller-looking hair in as little as 90 days.
What sets Vegamour apart is its commitment to clean beauty without compromising results. The star ingredient, mung bean extract, is packed with peptides that have been shown in clinical studies to improve hair density by up to 52% and reduce shedding by 76% after three months of use. Red clover works alongside it to block DHT naturally, addressing one of the primary causes of hair thinning at the hormonal level.
The lightweight, non-greasy formula absorbs quickly into the scalp without leaving any residue, making it perfect for all hair types including fine or oily hair. Users report noticing less shedding within the first month, with visible new growth and increased thickness becoming apparent around the 90-day mark. The serum has a subtle, pleasant scent that doesn't interfere with other hair products or fragrances.
What makes this our top pick is its universal appeal. Whether you're dealing with postpartum hair loss, stress-induced shedding, aging-related thinning, or simply want to maximize your hair's potential, Vegamour delivers consistent results. The brand's transparency with clinical trials and real user testimonials adds credibility that many competitors lack.
- Key Ingredients: Mung bean extract, red clover, curcumin, nicotinamide
- Pros: Vegan and cruelty-free, no harsh chemicals, suitable for sensitive scalps, clinical studies show visible results
- Cons: Higher price point, requires consistent use for 3+ months
