Sai Zen Ingredient Series Vol.2 | Boost Scalp Circulation Naturally with Loquat Leaf & Banaba

“Your hair feels flat lately?”
“Worried about thinning or increased shedding?”
“Does your scalp feel tight or lacking circulation?”
If so, you’re not alone.
One of the key reasons hair can lose its fullness and strength is poor blood circulation.
When blood flow to the scalp slows down, the follicles may not receive enough nutrients, leading to a tired scalp and fragile hair over time.
Sai Zen’s Natural Volume Shampoo was created out of love for my mother, whose sensitive skin couldn’t handle chemical-based shampoos.
I wanted to craft something so gentle that even a baby could use it — a shampoo that nurtures both scalp and spirit.
With over 28 years of experience as a hairstylist, I carefully selected herbs known for their ability to support scalp circulation and vitality.
Among these botanical ingredients, Loquat Leaf Extract and Banaba are two of the most remarkable.

Loquat Leaf Extract — Purifying and Nourishing from Within
For centuries, loquat leaves have been valued in traditional wellness practices as “leaves that maintain health.”
The star component, amygdalin (vitamin B17), is known for its cleansing and balancing qualities.
- Helps purify and rebalance the blood environment *
- Promotes smoother circulation so nutrients reach the scalp *
- Supports a healthy foundation for strong, beautiful hair *
In our modern, high-stress lifestyle, where circulation easily becomes sluggish, loquat leaf offers gentle, natural support for scalp wellness.

Banaba — A Perfect Partner for Loquat Leaf
Banaba leaves contain corosolic acid, traditionally known for helping balance blood sugar levels.
When combined with loquat leaf extract, banaba works synergistically to promote scalp vitality.
- Encourages smooth blood flow *
- Enhances the effects of loquat leaf extract *
- Helps maintain a calm, balanced scalp environment *
By pairing these two botanicals, Sai Zen’s formula strengthens the scalp’s natural rhythm — supporting healthier-looking, more resilient hair.
As a final thought
Behind many concerns about thinning hair lies a simple cause: insufficient scalp circulation.
Sai Zen’s Natural Volume Shampoo blends loquat leaf extract, banaba, and other plant-based ingredients to help nourish and balance the scalp naturally — supporting volume, resilience, and vitality for your hair.
