L-Arginine for Hair Health: How It Works?

L Arginine for Hair Health


Arginine is one of the most important amino acids in keratin, the hair building structure. Thinning hair is the result of reduced growth. Before discussing the potential of arginine to support hair growth, we will first look at why hair loss and damage happen. Hair loss may occur because of many different hereditary or environmental factors. Some common causes of hair loss affecting men and women include:

  • Aging.
  • Avoiding nutrient rich diet.
  • Hereditary.
  • Hormonal imbalance
  • Medical condition or medications.

The most common reasons for hair loss in men are

  • Male-pattern baldness, also called androgenic alopecia, is the top cause of hair loss in aging men and caused due to DHT hormone imbalance.
  • Dihydrotestosterone (DHT) is a sex hormone derived from testosterone that can cause male hair loss, specifically in aging men.

The most common reasons for hair loss in women are

  • Female pattern baldness – With female pattern baldness, thinning occurs on the top and crown of the head. This thinning in women often starts as a widening of the centre hair part that leaves the front hairline unaffected.
  • Telogen effluvium – With telogen effluvium, you won’t lose all the hair on your head. But it can become very thin. It is usually seen 2-3 months after a triggering event like viral fever.

Benefits of Arginine on hair health:

  • Improving blood circulation- Arginine boosts nitric oxide levels, aiding in artery relaxation and reducing blood pressure. This enhances cardiovascular health and facilitates increased blood flow to the scalp, promoting hair growth by nourishing hair follicles. Arginine enhances blood circulation to hair follicles, ensuring optimal oxygen and nutrient supply for hair growth.
  • Hair strengthening – Arginine not only stimulates hair growth but also strengthens existing strands. Clinical studies have shown a 21% increase in hair strength after one application of an arginine-based solution, with continued improvement over time on individuals with bleached hair.
  • Hair damage – With antioxidant properties, arginine combats free radicals, reducing hair breakage and damage. It forms a protective coating over hair, locking in moisture and safeguarding against product and heat-induced damage, particularly beneficial for bleached or colored hair.
  • Hair fall control- By improving scalp nourishment and stimulating hair follicles, arginine minimizes hair loss.
  • Hair elasticity – It enhances hair elasticity by promoting collagen production, crucial for maintaining hair structure and resilience.
