Another cause stems from sun exposure. When hair and scalp are frequently exposed to UV radiation during summer, hair shedding intensifies come autumn. Additionally, dry air strips the scalp of moisture, reduces sebum production, and allows dead skin cells to accumulate, clogging pores and weakening hair follicles, leading to increased hair loss.
The significant temperature fluctuations between day and night in autumn also weaken hair’s resistance, making strands dry and prone to breakage. However, this condition is temporary. Hair naturally follows a three-phase cycle: growth, resting, and shedding, after which new hair grows as usual.

Autumn is when women experience more hair breakage and shedding compared to other times of the year.
Many have panicked upon seeing clumps of hair fall during showers, wondering if it’s a sign of illness. Instead of relying solely on anti-hair loss shampoos, some have turned to natural remedies—washing hair with perilla leaves, a humble yet effective solution for reducing hair loss.
Why do perilla leaves combat hair loss?
Perilla leaves have long been valued in traditional medicine, serving as both a culinary herb and a beauty aid. According to Assoc. Prof. Dr. Trần Công Khánh (Center for Research and Development of Traditional Medicine), perilla leaves offer surprising benefits for skin and hair care. Perilla water can be used for bathing to moisturize, prevent dryness, slow aging, and fade dark spots. When used for hair washing, it leaves hair smooth, dandruff-free, and significantly reduces hair loss.
Perilla leaves are not only a common kitchen herb but also a “green secret” for maintaining strong, shiny, and naturally less shedding hair.
This effectiveness comes from the rich nutrients and natural compounds in perilla leaves.
Abundant vitamins and minerals: Perilla leaves are packed with vitamins A, C, and minerals like calcium, iron, and zinc. These nutrients nourish hair follicles, promoting faster and stronger hair growth.
Powerful antioxidants: Flavonoids and polyphenols in perilla leaves protect hair from free radical damage, slow aging, and prevent hair loss due to stress or aging.
Anti-inflammatory and antibacterial properties: Perilla leaves cleanse the scalp, eliminate bacteria, reduce itchiness, treat dandruff, and improve scalp health.
Enhanced blood circulation: When perilla water is used for washing or massaging, its active compounds penetrate deeply, improving blood flow. This nourishes hair roots, reducing breakage and shedding.
Perilla water and the 3 best times to drink it
3 Perilla-Based Recipes for Luscious Hair Growth
Using perilla leaves correctly significantly reduces hair loss while promoting faster, thicker hair growth. Here are three simple home recipes:
1. Perilla Hair Wash
– Wash 20–30 fresh leaves, boil in 1 liter of water for 10 minutes.
– Strain the liquid, let cool, and use to wash hair 2–3 times/week.
– Massage the scalp for 5 minutes during washing for deep absorption.
After 2 weeks of using perilla water, dandruff decreases significantly, hair becomes smoother, and shedding noticeably improves.
2. Perilla Leaf Pulp Scalp Scrub
After boiling, retain the leaf pulp. Let cool, then gently scrub the scalp. This deeply cleanses, stimulates hair follicles, and promotes healthy hair growth from the roots.
3. Perilla Hair Mask
– Blend 15 perilla leaves with 2 tablespoons honey and 1 tablespoon coconut oil.
– Apply evenly to scalp and hair, leave for 20–25 minutes.
– Rinse with warm water, use twice/week.
After 4–6 applications, hair becomes thicker, and new growth becomes visible.
4. Perilla Oil
– Soak 50g dried perilla leaves in 200ml olive oil for 2 weeks in a dark place, shaking daily.
– Strain the oil, apply to the scalp 1 hour before washing, use twice/week.
This method is especially effective for dry hair, making it stronger and shinier.
Tips for Using Perilla Leaves for Hair Care
Prefer fresh leaves: Fresh perilla leaves yield the best results. If unavailable, dried leaves can be used.
Patch test: For sensitive scalps, test on a small area first to avoid irritation.
Avoid overuse: Use 2–3 times/week. Excessive use can dry the scalp, causing irritation and counterproductive effects.
