Category: Botanical hair-supporting active
Used in: Haircare, scalp serums, hair growth treatments

INCI

Cucurbita Pepo (Pumpkin) Seed Extract

Typical Usage Levels

• 0.5% – 3% in leave-on scalp serums and hair-support formulations
  

Used at optimized levels to support follicular environment and androgen-related pathways without hormonal alteration.

What This Ingredient Does

Pumpkin seed extract is a plant-derived bioactive rich in phytosterols (including beta-sitosterol), essential fatty acids, and antioxidant compounds. These components are studied for their role in supporting hair follicle health, particularly in cases of androgen-sensitive hair thinning.

In hair biology, pumpkin seed extract is associated with modulating the local effects of dihydrotestosterone (DHT) at the follicular level. It does not alter systemic hormone levels. Instead, it helps support a healthier follicular environment by influencing enzyme activity linked to androgen metabolism and reducing oxidative stress around the hair root.

Clinical and nutritional studies suggest that pumpkin seed extract may help reduce progressive hair thinning, improve hair thickness, and support overall hair density when used consistently. In topical formulations, it functions as a supportive anti–hair fall botanical, especially valuable in early to moderate thinning.

Benefits

• Helps reduce hair fall linked to androgen sensitivity
  
• Supports healthier follicle function and scalp environment
  
• Helps improve hair thickness and density over time
  
• Provides antioxidant support to follicles
  
• Non-hormonal support suitable for long-term routines
  

Who It’s Suitable For

• Androgen-sensitive hair thinning in men and women
  
• Progressive hair fall or reduced hair density
  
• Individuals seeking botanical, non-drug hair support
  
• Long-term scalp care and hair retention routines
  

It is frequently combined with saw palmetto, biotin, zinc, amino acids, and antioxidants to address multiple internal hair health pathways.

Note by Dr. Su (M.D. Dermatologist)

Pumpkin seed extract is a useful botanical for supporting androgen-sensitive hair fall. When used consistently in scalp formulations, it helps maintain follicle health and supports hair density without interfering with hormonal balance.
