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

THORN & BERRY Hair Growth Serum is a lightweight, peptide-rich scalp treatment designed to strengthen strands and improve the appearance of hair thickness and density.

This fast-absorbing serum blends multi peptides, biotin, botanical DHT-supporting extracts and topical caffeine in a non-greasy base to refresh the scalp and support the look of fuller hair. Formulated for daily use and all hair types, it targets weakened, thinning hair with ingredients that help fortify follicles, hydrate the scalp, and reduce visible shedding without heavy build-up or harsh sulfates.

How does this serum help hair look fuller?

The formula uses peptides, biotin and keratin-building amino acids to strengthen fragile strands and improve hair elasticity. By supporting strand resilience and scalp condition, it enhances the visual density of hair over time when used consistently.

• Multi Peptide Complex including Copper Tripeptide-1 and Acetyl Tetrapeptide-3
• Hydrolyzed keratin plus amino acids to rebuild damaged fibers
• Biotin and niacinamide to support hair shaft integrity and shine

What makes the scalp feel healthier after use?

Active botanicals, soothing agents and lightweight humectants work together to balance oil, calm irritation and deliver lasting moisture. The non-oily texture absorbs quickly so the scalp feels refreshed rather than weighed down.

• Glycerin, panthenol (vitamin B5) and bisabolol for hydration and calming
• Tea tree, peppermint and rosemary oils to invigorate without residue
• Quick-absorbing base that reduces buildup on hair and scalp

Which natural ingredients help reduce visible shedding and support a balanced scalp?

A blend of botanical extracts and oils helps create scalp conditions that can minimize the look of shedding and support stronger strands. These ingredients are chosen for their traditional use in scalp and hair care rather than medical claims.

• Saw palmetto, pumpkin seed and nettle extracts as natural DHT-supporting botanicals
• Green tea, horsetail and licorice root for antioxidant and fortifying properties
• Topical caffeine and zinc for invigorating the scalp and supporting resilience

How do I use this serum and when will I see results?

Apply the serum directly to the scalp once daily or as directed, focusing on thinning areas and gently massaging for even distribution. Visible improvements in texture, shine and the overall appearance of fullness typically appear with consistent use over several weeks, though timing varies by individual.

• Use daily on clean, dry or damp scalp; massage 1–2 drops per target area
• Lightweight formula layers easily with styling products and treatments
• Packaged in the USA and free from sulfates, parabens and harsh chemicals
