Hair thinning and shedding are concerns that affect millions of people worldwide. Many people seek solutions to restore thickness and promote new growth, whether due to stress, genetics, aging, or hormonal imbalances. With many products claiming miracle results, knowing what works is hard.

Science-backed hair growth treatments exist, and when used together as a system, they deliver results that individual products alone can’t match. In this guide, we have curated the best products for hair growth and thickness for women, each chosen for its effectiveness, clinical support, and ability to target various causes of hair loss.


Why a Multi-Product Approach for Hair Growth Works Best 

A single factor rarely causes hair thinning, so a one-size-fits-all treatment often falls short of expectations. The most effective path to achieving thicker, fuller hair involves addressing multiple root causes, including poor scalp health, DHT buildup, weakened follicles, and nutritional deficiencies. That’s where a multi-product strategy excels.


You create an environment where hair can thrive by combining different treatment types, such as Low-Level Laser Therapy (LLLT), topical serums, scalp-stimulating tools, and nutritional support. This approach accelerates regrowth, improves hair quality, and reduces future shedding. Think of it as a full-spectrum system: targeting the scalp, follicles, and body from the inside out.

The best part? It’s easier than you think. We’ve curated the 7 most effective products at BiohackWorld to help you build your hair growth routine. The products are trusted by dermatologists, backed by science, and are women’s and men's best hair growth and thickness products.

Top 7 Best Products for Hair Growth  

Below are seven highly effective products for thinning hair at BiohackWorld that work synergistically to promote hair regrowth, improve thickness, and support long-term scalp health. Whether you're addressing early thinning or advanced shedding, these products can be tailored into a personalized routine for both men and women.

1. Capillus Synergy Kit


The Capillus Synergy Kit is your complete hair health system in one convenient package. Designed for daily use, it includes four science-backed products: a DHT-blocking shampoo, a restorative conditioner, a topical serum with biomimetic peptides, and a comprehensive hair growth supplement fortified with biotin and collagen.


Each step is critical, like cleansing the scalp to remove buildup and DHT, strengthening hair strands from the outside, stimulating follicles with concentrated serum, and replenishing the body with nutrients essential for hair production. The synergy of internal and external care helps users see faster and more sustainable results, making this kit ideal for anyone starting or refining their hair growth journey.

2. Capillus SPECTRUM Laser Cap


Harnessing the power of Low-Level Laser Therapy (LLLT), the Capillus SPECTRUM Laser Cap delivers clinical-grade scalp stimulation in just 6 minutes a day. With 202 medical-grade laser diodes, the cap offers full-head coverage, energizing dormant follicles and extending the hair growth phase.


It’s FDA-cleared for safety and efficacy, and its flexible-fit design makes it comfortable to wear during everyday activities. Ideal for users experiencing mild to moderate hair loss, especially in the crown and parting areas, the Capillus SPECTRUM works well as a stand-alone treatment or in conjunction with topical solutions and supplements for enhanced regrowth and reduced shedding.

3. Capillus Derma Roller


Microneedling for hair regrowth has gained immense popularity, and for good reason. The Capillus Derma Roller features 540 ultra-fine titanium needles at a safe 0.25mm length, making it ideal for home use without causing scalp damage. Creating tiny micro-channels in the scalp stimulates blood circulation and triggers the body’s natural healing response, including increased collagen production.


More importantly, it allows topical treatments, such as serums, to absorb more effectively, thereby boosting their potency. Use it 2–3 times a week on a clean scalp to improve follicular health, boost serum performance, and create an optimal environment for new hair growth.

4. Capillus Hair Supplement


Nutrition plays a massive role in hair health, and the Capillus Hair Supplement is specifically designed to address common deficiencies that lead to thinning. It combines essential ingredients like biotin, zinc, silica, vitamin D, and B-complex vitamins, nutrients often lacking in modern diets.


In addition, it includes hydrolyzed collagen to help support the hair’s keratin structure and improve elasticity and strength. Unlike general multivitamins, this supplement targets hair regrowth and is safe for both men and women. Daily, it helps fortify existing strands while supporting stronger, thicker hair growth over time.

5. Capillus Hair Serum


The Capillus Hair Serum is a lightweight, non-greasy topical formula designed to revitalize thinning hair and strengthen follicles. Powered by biomimetic peptides, botanical extracts, and antioxidants, it helps reduce inflammation and oxidative stress, two major contributors to hair follicle miniaturization.

Apply it directly to areas of concern once or twice daily after microneedling or on its own. Over time, it helps reactivate weakened follicles, thicken strands, and improve scalp conditions that impair growth. The hair growth serum and minoxidil also pair exceptionally well with microneedling and laser cap therapy, amplifying their effectiveness.

6. Capillus Shampoo


A healthy scalp is the foundation of hair growth, and the Capillus Shampoo is designed to maintain that balance. Free from sulfates and harsh chemicals, it gently removes dirt, oil, and buildup without stripping the scalp’s natural oils.


 Its inclusion of natural DHT blockers, such as saw palmetto and nettle extract, sets it apart, helping to reduce hormonal interference with hair follicles. The formula also contains nourishing botanical ingredients that soothe irritation and improve scalp circulation. Whether you wash daily or a few times a week, it’s essential to a holistic hair care routine.

7. Capillus DHT Blocker


DHT (dihydrotestosterone) is one of the leading causes of pattern hair loss, particularly in men. The Capillus DHT Blocker supplement addresses this internally with a powerful blend of natural ingredients like saw palmetto, pygeum, pumpkin seed oil, and green tea extract.

These work together to reduce the body’s DHT levels, helping to preserve hair follicle function and slow the progression of androgenetic alopecia (AGA). It’s ideal for those experiencing genetic or hormonal thinning and is formulated to be safe and effective for both men and women. For best results, use it alongside topical DHT blockers and laser therapy.


Final Words

You can achieve fuller, healthier hair using a targeted, multi-product approach. The Capillus system, featuring science-backed laser therapy, topical treatments, and nutritional support, offers one of the most effective paths to hair regrowth and thickness for both men and women.

FAQs About the Best Products for Hair Growth

Q1: Do I need to use multiple hair growth products at once?

Yes, and here’s why: Hair loss is rarely caused by one factor. It often results from hormone imbalances, poor scalp health, weakened follicles, and nutritional deficiencies. A multi-step routine, such as pairing a laser cap with a DHT-blocking shampoo, nourishing supplements, and a serum, allows you to simultaneously target all these root causes.

Q2: Are hair growth products safe for women?

All the products featured here are formulated to be gender-neutral and safe for both men and women. They’re free from harsh chemicals, and many contain plant-based ingredients like saw palmetto, green tea, and collagen, making them men's best products for hair growth and thickness. Whether you're dealing with postpartum shedding, hormonal imbalances, or age-related thinning, these solutions can be tailored to your needs.


Q3: What results can men expect?

Most men notice reduced shedding within 60 to 90 days of consistent use, with visible regrowth and improved thickness appearing within 3 to 6 months. Results may vary depending on the severity of hair loss, age, and consistency of the routine. Men with early-stage hair loss tend to respond more quickly, especially when combining laser therapy with DHT blockers and nutritional support.


Q4: When will I start seeing visible improvements in hair growth?

Hair regrowth takes time, but most users begin to see improvements in hair texture, reduced breakage, and less shedding within the first 8–12 weeks. More noticeable changes, such as increased density and new growth, typically occur between 3 and 6 months with consistent daily use. Patience and consistency are key to long-term success.


Q5: Do I need to use these products forever?

Long-term maintenance is crucial if your hair thinning is caused by genetic or chronic factors, such as androgenetic alopecia (AGA). Like skincare or physical fitness, stopping treatment can cause progress to stall or reverse. Fortunately, many users find it easy to integrate these products into their lifestyles, especially with low-effort tools like the 6-minute Capillus Laser Cap or daily supplements.
