THORN & BERRY Hair Growth Serum for Thinning Hair — Rosemary & Saw Palmetto, Biotin Peptides for Thicker Fuller Hair

THORN & BERRY Hair Growth Serum is a lightweight, peptide- and botanical-powered scalp treatment designed to help thinning hair appear thicker and fuller when used daily.

If you’re noticing reduced density, increased shedding, or finer strands, this topical serum blends multi-peptides, biotin, topical caffeine, and natural DHT-supporting botanicals like saw palmetto and rosemary to create a scalp environment optimized for stronger-looking hair. The formula pairs repairing proteins such as hydrolyzed keratin with moisturizing humectants and antioxidant extracts to nourish roots and improve strand resilience without leaving a greasy finish.

How does this serum support visible hair density?

The serum combines targeted ingredients that help improve the appearance of fullness and reduce the look of thinning. Peptides (including copper tripeptide-1 and acetyl tetrapeptide-3) and niacinamide work to revitalize scalp tissues, while biotin and hydrolyzed keratin strengthen fragile strands to reduce breakage.

• Multi-peptide complex to support scalp and follicle vitality
• Biotin and keratin rebuild hair structure and reduce breakage
• Topical caffeine and zinc to invigorate the scalp
• Lightweight, non-greasy texture for daily layering

Which active botanicals are included and what do they do?

This formulation blends clinically familiar botanicals with supportive extracts to help maintain a balanced scalp. Saw palmetto, rosemary, pumpkin seed, and nettle are included for their traditional roles in scalp health, while tea tree and peppermint provide a refreshing, clarifying sensation.

• Saw palmetto and pumpkin seed for natural DHT-supporting action
• Rosemary oil and green tea for antioxidant and soothing benefits
• Peppermint and tea tree offer a cooling, clean scalp feel
• Licorice root and sea buckthorn provide anti-stress antioxidants

How should I use it in my routine and what results can I expect?

Apply daily to a clean, dry or damp scalp, massaging a few drops directly into areas of thinning or across the entire crown. Because it absorbs quickly and is free of sulfates and parabens, it layers well with styling products and should not cause buildup when used as directed.

• Use once or twice daily on targeted areas for best consistency
• Suitable for all hair types — fine, color-treated, or chemically processed
• Results are gradual; expect improved appearance of fullness with regular use over weeks
• Daily moisture and scalp comfort from panthenol, glycerin, and bisabolol

• Free from sulfates, parabens, and harsh chemicals
