SpoiledChild A22 Biotin Boost Hair & Scalp Serum — 50 ml Refill Capsule, Vegan & Lightweight

SpoiledChild A22 Biotin Boost Hair + Scalp Serum is a lightweight, vegan formula that combines biotin, niacinamide and rosemary oil to support stronger-looking hair and a healthier scalp.

This serum is formulated to nourish hair from root to tip while improving scalp condition and manageability. Free from parabens, sulfates and silicones, the 50 ml refill capsule offers a compact, eco-conscious option for everyday use. The fast-absorbing texture is designed to leave no greasy residue, making it easy to integrate into mornings or nightly routines. Dermatologically tested and suitable for a wide range of skin types, the product focuses on cosmetic improvement of hair thickness, texture and scalp comfort rather than therapeutic treatment.

How does this serum support hair thickness and appearance?

The formula pairs biotin with niacinamide to help hair look fuller and feel stronger. Biotin is included to fortify hair strands while niacinamide improves surface appearance and manageability. Consistent topical application aims to enhance the look of density and reduce fragility from daily styling.

• Contains biotin to fortify hair fibers and reduce breakage risk;
• Niacinamide smooths and improves hair texture for better light reflection;
• Lightweight delivery avoids weighing hair down;
• Daily use supports cumulative cosmetic improvement.

What does it do for scalp health and comfort?

Rosemary oil and supporting botanicals provide targeted nourishment to the scalp, helping it feel refreshed and balanced. The non-greasy serum is intended to restore a comfortable surface environment that can improve the look and feel of hair growth areas. It’s formulated to be gentle and suitable for sensitive skin types.

• Rosemary oil nourishes and helps calm the scalp surface;
• Vegan, clean formulation reduces exposure to harsh additives;
• Fast absorption minimizes residue under styling products;
• Dermatologically tested to support compatibility with varied skin types.

How do you use the A22 Biotin Boost Serum in a hair routine?

Apply a few drops directly to the scalp on clean, dry or slightly damp hair and massage gently until absorbed. Use daily for best cosmetic results; the refill capsule lets you replenish the 50 ml vessel sustainably. It layers well with conditioners and styling products because of its non-greasy finish.

• Dispense drops along the scalp parting and massage for even coverage;
• Use daily, morning or night, before styling products;
• Ideal for use after cleansing or on towel-dried hair;
• Refill capsule reduces single-use waste and fits the original bottle.

Is the serum safe for colored or chemically treated hair?

The formula is free from sulfates, parabens and silicones, which helps it remain compatible with many color and treatment routines. Because it’s non-stripping and quick-absorbing, it can be included in maintenance steps for processed hair. As with any new product, patch testing is recommended if you have known sensitivities or recent chemical treatments.

• Free from sulfates and parabens to protect treated hair;
• Non-greasy formula avoids buildup on color-treated strands;
• Dermatologically tested for general scalp compatibility;
• Patch-test advice if you recently had chemical processes.
