Ingredient Spotlight: Nettle Leaf Extract

in Scalp & Follicle Environment

A healthy scalp environment is essential for strong, balanced hair and Nettle Leaf Extract is one of the most versatile botanicals for supporting that foundation. Rich in naturally occurring vitamins, minerals and antioxidants, nettle has been used for centuries to support skin, circulation and overall vitality. In this spotlight, we explore what nettle is, how it supports the scalp, and why it plays a meaningful role in our formula.

What Is Nettle Leaf Extract?

Nettle (Urtica dioica) is a nutrient‑dense botanical traditionally used across Europe and North America. Despite its reputation for stinging when fresh, once processed it becomes a gentle, mineral‑rich extract containing naturally occurring vitamins A, C, E, K, B‑complex, iron, magnesium, calcium, potassium, silica, and polyphenols.

These nutrients, combined with its antioxidant profile, make nettle a popular ingredient in wellness formulas designed to support skin, scalp and hair vitality.

How Nettle Supports Hair & Scalp Health

Nettle contributes to a balanced scalp environment through several pathways:

Its antioxidant content helps protect the scalp from oxidative stress, a factor that can influence follicle comfort and overall scalp condition.
It is widely discussed for its potential influence on circulation, supporting the delivery of oxygen and nutrients to the scalp surface.
Its naturally occurring minerals and silica help support the structural environment around the follicle.
Traditional use and early research suggest nettle may help maintain scalp comfort, particularly in relation to dryness or flakiness.

Together, these properties make nettle a supportive botanical for maintaining a calm, nourished scalp - the foundation for healthy‑looking hair.

The Science in Simple Terms

Research into nettle focuses on three main areas:

1.) Antioxidant activity - Nettle contains polyphenols and flavonoids (flavonoids are the most common type of polyphenol) that help neutralise free radicals around the scalp (1.).

2.) Mineral density - Its naturally occurring iron, magnesium, silica and potassium contribute to overall nutrient availability.

3.) Hormone‑related pathways - Some studies explore nettle’s potential interaction with 5‑alpha reductase, the enzyme involved in converting testosterone to DHT (2.). While findings are early and not conclusive, this research contributes to nettle’s reputation in hair‑focused formulas.

How Nettle Complements This Category
