脫髮有甚麼成因？

1. 荷爾蒙失衡：掉髮的隱形元兇

DHT 與雄性禿（Androgenetic Alopecia）

二氫睾酮（DHT）是睾固酮的衍生物，當 DHT 與頭皮毛囊受體結合時，會導致毛囊萎縮，進而引發男性或女性型禿髮。即使是女性，也會因雌激素代謝產生 DHT，因此維持荷爾蒙平衡對預防脫髮至關重要。

懷孕與產後掉髮

懷孕期間，雌激素水平升高可延長頭髮的生長期，但產後雌激素驟降，可能導致大量脫髮。此外，月經週期與更年期的荷爾蒙變化也可能加速脫髮。

甲狀腺功能不平衡

甲狀腺功能過低（甲狀腺低能）會影響新陳代謝，導致毛囊功能受損，使頭髮變得乾燥、脆弱；而甲狀腺功能過高致新陳代謝過快，則可能引發過度脫髮。

長期壓力與皮質醇（Cortisol）

壓力會提高皮質醇水平，這種分解代謝型荷爾蒙會破壞身體組織，包括毛囊，進而干擾生長週期，導致髮量減少。

2. 營養缺乏：頭髮健康的關鍵

鐵質缺乏與頭髮生長

經期過多或鐵質吸收不良可能導致貧血，鐵質是形成血紅蛋白的主要成份，血紅蛋白把氧氣及營養輸送至身體不同細胞包括頭髮細胞，缺乏鐵質影響毛囊氧氣及營養供應，導致脫髮。

維生素 B 群與腸道健康

生物素（Biotin）與維生素 B 群的不足，常與腸道問題（如脹氣、消化不良）有關。腸道菌群的健康如同「土壤」，能促進毛囊這些「根部」的生長。保護腸道微生物菌健康很重要，因為腸道微生物會產生氨基酸，令頭髮生長。腸道 微生物群被破壞可導致頭皮微生物破壞，進而導致頭皮屑、 脫髮及皮膚病等問題。

如何治療脫髮？個人化方案打造健康髮質

第一步：全方位健康檢測

透過荷爾蒙檢測（DHT、皮質醇、甲狀腺素）與營養評估（鐵質、維生素 B 群），找出脫髮的根本原因。此外，頭皮分析可幫助評估毛囊健康，進一步制定專屬療程。

第二步：個人化的脫髮治療方案

荷爾蒙療法

• 針對 DHT 過高者： 可使用 DHT 阻斷劑（如非那雄胺 Finasteride），但需監測副作用（如性慾降低）。年長男性可搭配睾固酮補充，以維持活力。

• 針對雌激素或甲狀腺失衡者： 可透過荷爾蒙替代療法（HRT）或甲狀腺藥物來調整平衡。

營養補充與飲食調整

針對營養缺乏者： 可使用高品質的醫學級補充品，並透過飲食計畫來改善營養狀況。若腸道吸收不佳，可考慮營養靜脈注射或益生菌療程來提升吸收效率。

生活方式調整

壓力管理：冥想、運動等方式可降低皮質醇的影響，減少壓力引起的掉髮。 頭皮保養：頭皮按摩可促進血液循環，有助於毛囊健康。

第三步：先進的再生醫學療法

外泌體療法（Exosome Therapy）

外泌體是由幹細胞釋放的微小囊泡，其中含有生長因子與胜肽，可直接傳遞至頭皮，修復毛囊、刺激生長並延長頭髮生長週期。與傳統幹細胞療法不同，外泌體是細胞間的「訊號」，可精準調控細胞修復機制，提供長效且針對性的脫髮治療效果。 這種微創技術已成為頭髮再生領域的突破性療法。

為甚麼選擇整體健康策略治療脫髮？

脫髮 不僅僅是美觀問題，它更反映身體的內在健康。透過個人化治療，結合荷爾蒙調節、營養補充與再生醫學技術（如外泌體療法），能有效解決脫髮問題。建議尋求專業醫療機構，透過整合醫學與再生療法，為您制定專屬的生髮計畫。

Rates of melanoma, the deadliest form of skin cancer, has been rising for at least the last three decades, and this increase has been largely blamed on the exposure to (UV) light from the sun.

However a recent study published in the British Journal of Dermatology revealed that an epidemic of the disease has broken out among indoor workers. These workers get three to nine times LESS solar UV exposure than outdoor workers get, yet only the indoor workers have increasing rates of melanoma — and the rates have been increasing since before 1940.

There are two major factors that help explain this, and the first has to do with the type of UV exposure.

There are two primary types of UV rays from sunlight, the vitamin-D-producing UVB rays and the skin-damaging UVA light. Both UVA and UVB can cause tanning and burning, although UVB does so far more rapidly. UVA, however, penetrates your skin more deeply than UVB, and may be a much more important factor in photo-aging, wrinkles and skin cancers.

A study in Medical Hypotheses suggested that indoor workers may have increased rates of melanoma because they’re exposed to sunlight through windows, and only UVA light, unlike UVB, can pass through window glass. At the same time, these indoor workers are missing out on exposure to the beneficial UVB rays, and have lower levels of vitamin D.

Researchers wrote:
“We hypothesize that one factor involves indoor exposures to UVA (321–400nm) passing through windows, which can cause mutations and can break down vitamin D3 formed after outdoor UVB (290–320nm) exposure, and the other factor involves low levels of cutaneous vitamin D3. After vitamin D3 forms, melanoma cells can convert it to the hormone, 1,25-dihydroxyvitamin D3, or calcitriol, which causes growth inhibition and apoptotic cell death in vitro and in vivo. … We agree that intense, intermittent outdoor UV overexposures and sunburns initiate CMM [cutaneous malignant melanoma]; we now propose that increased UVA exposures and inadequately maintained cutaneous levels of vitamin D3 promotes CMM.”

To put it simply, UVB appears to be protective against melanoma — or rather, the vitamin D your body produces in response to UVB radiation is protective.
As written in The Lancet (vol 363, issue 9410, pp 728-730):

“Paradoxically, outdoor workers have a decreased risk of melanoma compared with indoor workers, suggesting that chronic sunlight exposure can have a protective effect.”

Your organs can convert the vitamin D in your bloodstream into calcitriol, which is the hormonal or activated version of vitamin D. Your organs then use it to repair damage, including damage from cancer cells and tumors. Vitamin D’s protective effect against cancer works in multiple ways, including:

• Increasing the self-destruction of mutated cells (which, if allowed to replicate, could lead to cancer)
• Reducing the spread and reproduction of cancer cells
• Causing cells to become differentiated (cancer cells often lack differentiation)
• Reducing the growth of new blood vessels from pre-existing ones, which is a step in the transition of dormant tumors turning cancerous

This applies not only to skin cancer but other types of cancer as well. Theories linking vitamin D to certain cancers have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory studies, according to epidemiologist Cedric Garland, DrPH, professor of family and preventive medicine at the UC San Diego School of Medicine.

LifeClinic Says:

LifeClinic recommends using the sun therapeutically, this means getting the proper exposure to optimize your vitamin D levels. This typically means exposing enough of your unclothed skin surface to get a slight pink color on your skin. Your exact time will vary radically depending on many variables, such as you skin color, time of day, season, clouds, altitude and age.

The key principle is to never get burned, while still spending as much time as you can in the sun during the peak hours, as it is virtually impossible to overdose as long as you don’t get burned.

The best time to be in the sun for vitamin D production is actually as near to solar noon as possible which is 1 PM in the summer for most (due to Daylight Saving Time). The more damaging UVA rays are quite constant during ALL hours of daylight, throughout the entire year — unlike UVB, which are low in morning and evening and high at midday.

Most people with fair skin will max out their vitamin D production in just 10-20 minutes, or, again, when your skin starts turning the lightest shade of pink. Some will need less, others more. The darker your skin, the longer exposure you will need to optimize your vitamin D production.

If you work in an office, or get limited opportunities to go into the sun at peak hours, we recommend you have your Vitamin D levels checked, which can be done on a simple blood test. If they are low, they can be easily supplemented with a daily vitamin D3 capsule.

Optimizing your levels of Vitamin D3 may not only just protect against malignant melanoma, but has also been shown to reduce the risk of getting cancer of the colon, prostate, breast and lymphoma.
