Overview
Weak, thinning hair needs more than surface-level care. ROYAL LINES Hair Serum is a lightweight leave-in treatment from the Hair Loss and Thinning Hair Care Line, enriched with biotin and keratin complex. It strengthens hair from the roots, reduces breakage, and supports healthier growth — while adding natural shine and smoothness with zero greasiness.

Part hair into four sections. Apply 1 ml (5-7 drops) directly to scalp using the applicator bottle, starting at the crown. Massage gently with fingertips for 1-2 minutes to boost absorption and circulation.
Use twice daily for best results — morning and night. The serum dries quickly and won't leave residue.
Continue for 8-12 weeks to see visible results. Hair growth is a gradual process, so consistency is key. If your scalp is sensitive, reduce application to once daily or every other day until your scalp adjusts.
For optimal results with Royallines Hair Serum Biotin Keratin Complex, pair regular application with a healthy diet rich in proteins and biotin. Keep the scalp clean and avoid applying other heavy products immediately after use.
