Moerie Hair Growth Serum Spray is a leave-in scalp treatment formulated with biotin, rosemary, fulvic acid and a botanical complex to strengthen hair and support fuller-looking strands.

This lightweight spray is designed for daily use on washed hair to nourish follicles, boost keratin-related support and improve the look of volume without heavy residue. The formula combines concentrates such as biotin and caffeine with a blend of 125 plant-derived nutrients, 77 minerals, 18 proteins and 5 vitamins to help maintain a healthier scalp environment and thicker-appearing hair. It’s non-GMO, suitable for color-treated hair, and comes in a convenient 150ml bottle for at-home application.

How do I use this serum to fit into my routine?

Application is simple and fast: spray directly onto a clean, damp scalp, gently massage to distribute, and leave it in—no rinsing required. Use daily for best consistency and pair with a nourishing shampoo and conditioner to maximize scalp clarity and strand support.

• Apply after washing and towel-drying hair.
• Target thinning areas with 2–4 pumps per section.
• Massage for 30–60 seconds to improve scalp contact.
• No rinse; style as usual.

What key ingredients are in the formula and what do they do?

The serum blends botanical extracts and targeted actives to support a healthier-looking scalp and stronger strands. Ingredients like biotin and fulvic acid work alongside caffeine and rosemary to nourish follicles and encourage keratin-related support without harsh chemicals.

• Biotin: supports keratin production for stronger hair feel.
• Fulvic acid: helps deliver nutrients to the follicle base.
• Caffeine: included to counteract typical scalp stressors.
• Rosemary and botanical complex: provide antioxidant-rich nourishment.

When can I expect to notice changes and how should I measure progress?

Individual response times vary; many users track small improvements in texture and manageability within a month, with more noticeable density and volume changes over several months when used consistently. Photographing the scalp and measuring daily hair shedding and styling ease are practical ways to monitor results.

• Initial texture improvements: often within 2–4 weeks.
• Visible volume and fullness: commonly seen over 2–3 months.
• Use consistent application for comparable results.
• Keep a photo log and note styling differences.

Is this safe for my hair type, scalp sensitivity, or colored hair?

Moerie’s serum is formulated for broad compatibility, including color-treated and chemically processed hair. It is non-GMO and free from heavy residues, but if you have an unusually reactive scalp, patch testing before full use is a good precaution.

• Suitable for all hair textures and color-treated hair.
• Lightweight, non-greasy finish for daily wear.
• Patch test recommended for sensitive scalps.
• Free from heavy oils that weigh hair down.

Who is this for: Moerie Hair Growth Serum Spray is for men and women seeking a simple, science-informed topical to support scalp health and thicker-looking hair. It fits people with early signs of thinning, anyone wanting extra daily volume without heavy products, and those who prefer botanical-forward formulations.
