Hesul Scalp Ampoule 40ml — Korean hair growth serum with biotin & natural caffeine, lightweight

Formulated for people experiencing thinning or fragile hair, this ampoule combines biotin, amino acids, natural caffeine and botanical extracts in a non-greasy, slightly acidic base to protect the scalp barrier and improve surface hydration. The 40ml bottle delivers a concentrated daily treatment developed with clean-beauty principles—no silicones or harsh sulfates—so it layers easily under styling products or sits comfortably on sensitive skin.

How does this ampoule support scalp comfort and hydration?

The formulation focuses on restoring scalp moisture and elasticity while reducing visible flakiness and irritation. A slightly acidic pH helps maintain the skin barrier, and soothing botanical oils calm reactive scalps without heaviness.

• pH balanced at 5.0–6.5 to protect the scalp barrier
• Ingredients that boost surface hydration and elasticity
• Soothing kukui nut oil to reduce sensitivity and redness
• Clinical testing showing improvements within a four-week period

What active nutrients are in the serum and how do they work?

Key actives include biotin and amino acids to support hair fiber health, naturally derived caffeine to energize follicles at the root level, and beer yeast concentrate for protein-rich nourishment. Together they create a nutrient-focused environment intended to make hair look stronger and fuller with consistent application.

• Biotin and amino acids for hair structure support
• Natural caffeine to stimulate scalp circulation
• Protein-rich beer yeast to supply nutrients to the root area
• Antioxidant botanicals to protect and soothe the scalp

Will it feel heavy or irritate sensitive skin?

The ampoule is formulated to be lightweight and non-greasy, absorbing quickly so it won’t weigh hair down or leave a sticky residue. Free from silicones and common sulfates, it minimizes pore-clogging and potential irritants, making it suitable for those prone to sensitivity.

• Fast-absorbing, non-greasy texture for daily layering
• No silicones or SLS/SLES/ALS/ALES included
• Designed for sensitive scalps with calming ingredients
• Can be used under styling products without buildup

How do I use the Hesul Scalp Ampoule in my routine?

Apply directly to a dry or towel-dried scalp once or twice daily, massaging gently to distribute the serum along the hairline and crown. Regular use is recommended to see gradual improvements in scalp condition and hair appearance.

• Dispense a few drops to targeted thinning areas or across the whole scalp
• Massage gently until absorbed; do not rinse out
• Use daily for best results; fits into morning or evening routines
• Works alongside shampoos, conditioners, and styling treatments

Who is this for: Hesul Scalp Ampoule suits people noticing hair thinning, reduced volume, or a dry, reactive scalp who want a clean, clinically minded daily treatment. It’s a practical option for anyone seeking a lightweight, science-informed ampoule to add targeted nutrition to the scalp without silicones or harsh surfactants.
