Dr. Eric Berg points out that zinc is a key trace element for maintaining healthy hair , but too much zinc can also lead to hair loss because it causes copper deficiency. The following is a complete summary of the relationship between zinc and hair:

🧠 Basic functions of zinc

Participating in more than 300 enzyme reactions
Supports immune system, testosterone, taste, vision, reproductive health, and skin health.
Especially important for hair growth

🧬 The effects of zinc deficiency on hair

Hair follicle atrophy → hair cannot grow normally
Insufficient collagen and keratin → hair becomes thinner, more brittle, and loses elasticity
ALP enzyme failure → imbalance in three growth stages, leading to hair loss
Hair follicles cannot obtain enough energy → growth stops

⚠️ The dark side of excessive zinc: causing copper deficiency

Zinc and copper are like a seesaw – more zinc means less copper.
Copper deficiency can lead to:

Hair becomes thin, brittle, and falls out
Hair loses pigment → premature graying
Unstable hair follicle structure → loose scalp
Enzyme inactivation → decreased hair retention

📏 Recommended intake and proportion

situation	Zinc intake	Copper intake	Proportion Recommendation
General adults	40mg /day	Approximately 1 mg /day	10:1
Inflammation/autoimmune disease	The dosage can be increased to 200–250 mg /day in a short period of time.	Simultaneous increase in copper intake	Maintain a 10:1 ratio

🤢 Symptoms of zinc poisoning (side effects of overdose)

Nausea and vomiting
decreased appetite
Abdominal pain, diarrhea
Headache

🚫 Factors that hinder zinc absorption

Intestinal inflammation → decreased small intestinal absorption
High-carbohydrate diet, stress
Phytic acid in grains
High estrogen levels (birth control pills, hormone therapy)
Insufficient stomach acid → decreased zinc absorption

🥗 Recommended high-zinc foods

Oysters and shellfish
Red meat, seaweed
Animal-based foods such as cheese
The absorption rate is approximately 20–40% , with better absorption in individuals with healthy gut systems.

🧾 Conclusion: Stop supplementing with zinc haphazardly; true hair care comes from achieving a balanced diet.

Hong Kong people value appearance, hair health, and immunity, but more zinc isn't always better; excessive zinc can disrupt the copper balance and lead to hair loss . Starting today, a high-zinc food, a copper supplement, and a balanced ratio will lay a solid foundation for your hair!

Don't be misled by the myth that "zinc supplementation equals hair growth." Understanding balance, absorption, and proper combinations is key to true health! 💪🧠💇♂️
