The viral hair growth serum that's taking over your FYP. Science-backed, dermatologist-approved, and it actually works. No cap.
GrowthLab's Hair Growth Serum is a concentrated scalp treatment formulated with three clinically-studied actives that work together to reawaken dormant follicles, nourish the scalp, and accelerate visible growth.
Targets hair follicle stem cells directly at the root using Redensyl™ — the most advanced follicle-activation compound in modern trichology.
Capixyl™ peptide complex mimics the scalp's natural growth signaling to keep hairs in anagen (growth) phase significantly longer.
Our biotin-caffeine-zinc triad feeds follicles the exact micronutrients depleted by stress, heat styling, and modern diet deficiencies.
Three powerhouse ingredients. One unstoppable formula.
Patented compound that directly activates DHQG molecules in hair follicle stem cells — triggering the anagen phase of growth on a cellular level. Developed over 8 years of trichology research.
A biomimetic peptide that inhibits the production of DHT — the hormone most responsible for follicle miniaturization. Clinically proven to reduce hair loss by extending the anagen cycle.
Caffeine penetrates to the follicle root and reverses the inhibitory effects of testosterone on hair growth. Paired with B7 biotin to supercharge keratin production for thicker, stronger strands.
*Based on third-party clinical studies of individual ingredients. Results may vary.
No filters. No Photoshop. Just genuine transformations from our community.

✓ Verified PurchaseI have tried literally every single hair growth product on the market for the past 5 years. This is the only one that made me actually grab a ruler. I measured 2.2 inches of new growth at 30 days. I told my mom, my sister, my coworker. Everyone is on it now lol.

✓ Verified PurchaseMy hairline was receding for two years after postpartum hair loss. I saw this on TikTok, was skeptical but figured 60-day guarantee meant no risk. At week 3 my husband noticed baby hairs along my hairline. At week 5 my stylist literally said "what are you doing, your hair is growing like crazy." I cried honestly.

✓ Verified PurchaseThe texture of this serum is so lightweight — absorbs in like 60 seconds. I use it before bed and don't feel it at all. But the results speak for themselves. My hair is growing faster, thicker, and way less breakage than before. Currently on my 3rd bottle and not stopping.

✓ Verified PurchaseI did a full 30-day video diary on this. Measured my hair every day. The growth started slowing around day 10 then accelerated again — week 3 and 4 were insane. Ended up at 2.3 inches of verified new growth. Genuinely the most effective thing I've ever put on my scalp.
This is the offer that went viral. Stock runs out fast — people are buying in bulk. Don't sleep on this. Secure yours now while the deal is live.
The 3-step routine that 200K+ people swear by.
Start with a clean, slightly damp scalp. Gently towel-dry your hair after washing — the serum absorbs best when your scalp is warm and pores are open.
Part your hair into sections and apply 8–10 drops directly onto the scalp along each part. Focus on areas with the least density or where you want the most growth.
Use fingertips to gently massage in circular motions for 2–3 minutes. This increases blood flow to follicles and ensures the actives penetrate deep into the root zone. Don't rinse.
💡 Pro Tip: Apply before bed for best results. Nighttime is when your scalp regenerates — let the serum work while you sleep. Use consistently for 30 days minimum for optimal results.
We're so confident in GrowthLab that we offer a full 60-day no-questions-asked refund. If you don't see real, measurable hair growth within 60 days of consistent use — email us and we'll refund every cent. No drama, no hoops, no waiting.
