Key Ingredients

Every ingredient in the HXC-4 is unique to Hårklinikken alone. Each constituent was isolated and developed by our founder, Lars Skjøth, through years of scientific research, precise sourcing, testing, and development. The result is a set of proprietary ingredients that work in a unique synergy, cultivated and refined to standards distinct to our formula.

APPLE EXTRACT

Contains constituents that act on cellular pathways, including PKC signaling, which supports hair follicle activity and the shift into the active growth phase.

BURDOCK ROOT

Cleanses the scalp while providing anti-inflammatory, antibacterial, and antifungal properties around the hair follicle and encouraging optimal scalp conditions for hair growth.

CALENDULA OFFICINALIS (MARIGOLD)

Contains soothing compounds and antioxidant flavonoids that help calm and condition an irritated scalp with antimicrobial properties.

MILK-DERIVED CONSTITUENTS

Derived uniquely from a specific breed of Scandinavian cows and perfected for more than two decades of scientific research and development, formulated to help balance the scalp microenvironment and support delivery of other ingredients.

How to Use

Part your hair cleanly down the middle. Starting at the hairline, place small dots of serum along the part, moving gradually toward the crown. Aim for two dots per section, spaced approximately two inches apart.

Work across the scalp in rows about half an inch apart, ensuring even coverage of the top, sides, and crown.

After completing each row, use your fingertips to gently rub the serum into the scalp to ensure proper absorption.

Once all serum is applied, slide your fingers beneath the hair and place them firmly on the scalp. Using a gentle squeezing motion, massage the entire scalp for at least one minute (up to five), repositioning your fingers every 10 – 15 seconds.

Leave the serum on for a minimum of six to eight hours before washing for optimal effect.
